Prevent slipping by treating every screw as a fit-and-control problem: use the exact recess profile, choose the largest bit that fills it snugly, keep the shaft straight, press steadily, and limit torque and speed. Add a correctly sized pilot hole when the material resists the screw. If the bit starts climbing out, stop immediately, reseat it or change the bit, and do not continue with a damaged tip or recess.
Why screwdriver bits slip and screw heads strip
A screw head strips when the driving bit loses reliable contact with the recess and rides up its edges. The torque that should turn the fastener is then concentrated on a small portion of the recess. The harder driver material can smooth or deform the softer screw recess, making the fit even worse. Continuing to drive after that point rapidly changes a usable screw into one that is difficult to remove.
Most slipping starts with one of four application errors identified in Bosch DIY guidance: the bit size does not match the screw, the bit is held at an angle, it tilts during driving, or downward pressure is too low. Excessive force can also make damage worse once the bit has begun to cam out. Resistance from the workpiece, a cross-threaded screw, or a worn bit can produce the same symptoms even when the initial setup was correct.
Match the bit to the screw head
Identify the recess profile
Look closely at the screw before choosing a bit. A cross-shaped recess may be Phillips or another cross-drive standard; it is not safe to assume that every cross head is interchangeable. Other common profiles include JIS, Pozidriv, Torx, tri-point and flathead. Use the profile specified for the fastener rather than forcing a similar-looking driver. A bit that appears to fit can still have the wrong flank angles or engagement depth.

An interchangeable screwdriver bit set is useful when your work includes several standards, because it lets you test the correct family instead of substituting the nearest bit. Keep profiles separated in their case so a hurried selection does not put a nearly compatible bit back into service.
Choose the largest size that fits snugly
Compare adjacent sizes in the same bit family. The correct bit should fill the recess without rocking, while still dropping fully to the bottom. Andrew Goldheart of iFixit describes the trade-off this way: “Use the right size bit. Too small and you float inside the recess; too large, and you’re not getting the best turning power.” A bit that is too small contacts only the inner edges and can spin inside the head. A bit that is too large may touch the opening without seating deeply, reducing useful contact and damaging the rim.
Do not hammer an oversized bit into a recess or use the bit as a chisel. If no size fits cleanly, stop and obtain the correct profile or replace the fastener.
Inspect the bit and screw before driving
Reject worn or damaged bits
Examine the tip under good light. Replace a bit with a rounded point, chipped corners, twisted flanks or a visible bend. Wear changes the shape that is supposed to engage the recess, so a previously reliable setting can begin to slip. Bosch advises replacing bits that no longer fit snugly; using a damaged bit often strips a series of screws rather than just one.
Clean the recess
Remove paint, sawdust, metal chips and dirt from the screw head. Debris prevents full seating and can make a correct bit feel loose. Brush or blow the recess clear, then check it again. Do not pack material into the head by repeatedly spinning the bit at high speed.

Check the fastener and workpiece
A screw that is bent, cross-threaded or entering a blocked hole may require more torque than the recess can transmit. If the screw suddenly becomes much harder to turn, stop and investigate rather than increasing power. An improperly threaded screw becomes increasingly difficult to tighten and can permanently damage the hole, according to iFixit repair guidance.
Keep the driver on-axis
Place the shaft directly over the screw so it is collinear with the fastener. iFixit’s instruction is to “keep the driver directly in line with the screw, with the shaft directly over the screw head.” Angling the tool loads one side of the recess and encourages the bit to climb out. A tilt that seems minor at the start becomes more severe as the bit rotates.

Use your free hand to stabilize the tool body or the workpiece. For a horizontal or overhead job, support the drill or driver so its weight does not pull the shaft sideways. If access forces you to work at an angle, use a right-angle attachment or change the workpiece position rather than accepting a poor engagement angle. Do not rely on downward force to compensate for a visibly misaligned shaft.
Seat the bit and apply steady pressure
Push the bit fully into the recess before rotating. Maintain continuous, moderate pressure along the shaft while the fastener turns. Too little pressure allows the bit to bounce or pop out; excessive force can crush the recess once cam-out has started and can make it harder to feel a developing problem.
With a hand driver, place one hand on the handle and use the other to keep the shaft aligned when practical. Turn slowly enough to sense changes in resistance. With a drill/driver, brace the tool without squeezing the trigger abruptly. If the bit rises even slightly, release the trigger, reseat it and reassess the size, profile and alignment.

Control a drill/driver’s speed and torque
Start slowly
Begin at low speed, particularly on small screws, brittle materials or visible finishes. A slow start lets the bit settle into the recess and gives you time to correct alignment before high rotational energy causes damage. Increase speed only after the screw is tracking correctly and resistance is predictable.
Recommended Free Tools
Use the clutch
Select a low gear and a clutch setting appropriate to the material and screw. Bosch states that choosing the correct torque setting helps prevent stripped screw heads and damaged materials. Start conservatively and increase the setting only when the screw stops before reaching the intended seated position. Stop when the head is snug; driving farther can crush a surface, over-compress a joint or strip the recess.
Clutch numbers are not universal torque values. The actual result depends on the tool, battery condition, bit, screw, material and driving speed. Treat the numbered collar as a repeatable starting point for your particular tool, not as a specification that applies to every drill.
Know when to switch to hand power
A drill with adjustable clutch is efficient for repeated work, but a hand driver maximizes feel at the final turns. Use the drill to run a screw most of the way, then finish by hand when the joint is delicate, the head is small or the final seating depth matters. This removes stored rotational energy from the most damage-prone part of the operation.
Reduce resistance with a pilot hole
In wood, plastic and other yielding materials, a pilot hole creates a guided path and reduces the force needed to start and advance the screw. It is especially useful when the screw is large, the material is dense, the grain is likely to split, or the direct-driving force is high enough to make the bit slip. DAP’s hinge-repair procedure specifically calls for drilling new pilot holes before reinstalling screws.

A pilot hole is not a substitute for a correctly fitted bit. Select the hole size for the fastener and material, keep the drill aligned, and clear the hole before driving. If the screw still meets abnormal resistance, stop and check for a hidden obstruction or a damaged thread instead of simply raising the clutch.
Hand driver versus drill/driver
| Option | Strengths | Risks and controls | Best use |
|---|---|---|---|
| Hand screwdriver | Maximum feedback and precise control of the final turns | Slower; requires enough access and sustained pressure | Small, delicate or easily damaged fasteners; final tightening |
| Drill/driver | Fast and consistent for many screws; clutch can limit torque | High speed or excessive clutch setting can strip heads or damage material | Repeated driving when low speed and clutch settings are available |
Whichever tool you use, the fundamentals remain the same: exact profile, snug size, clean recess, straight shaft and controlled pressure.
Optional grip aids
When a fastener is only marginally slippery, a friction aid may provide extra help after the basic setup is correct. DAP’s manufacturer instructions say to “Apply a drop of Liquid Grip to the screw head” and that “This improves grip and reduces stripping.” Use such a product sparingly and treat it as an aid, not a replacement for the right bit, straight alignment, steady pressure and torque control.
Grip products cannot repair a rounded recess, compensate for a wrong profile or make a cross-threaded screw safe to force. If the bit still climbs out after the aid is applied, stop and correct the mechanical cause.

- Identify the profile. Determine whether the recess is Phillips, JIS, Pozidriv, Torx, tri-point, flathead or another standard. Do not substitute a close-looking driver.
- Test adjacent sizes. Choose the largest bit that fills the recess snugly, seats completely and does not rock or require force.
- Inspect the hardware. Reject a bent, chipped or worn bit. Replace a screw with a badly damaged recess when the job allows it.
- Clean the head. Remove debris, paint and chips so the bit can reach the bottom of the recess.
- Prepare the workpiece. If wood, plastic or another yielding material offers high resistance, make an appropriately sized pilot hole. Confirm that the screw is not cross-threaded.
- Seat and align. Push the bit fully down and hold the shaft directly in line with the screw.
- Start slowly. Use gentle trigger pressure or slow hand turns while maintaining moderate downward pressure.
- Set the torque. On a drill/driver, select low gear and a conservative clutch setting suited to the material and fastener.
- Watch the bit. If it rises, chatters or tilts, stop immediately. Reseat it, change size or profile, and correct the alignment before continuing.
- Stop at snug. Release the trigger or stop turning once the screw is seated. Do not use extra torque to bury the head unless the fastener and material specifically require it.
- Inspect afterward. Check the recess and bit for fresh deformation. Remove any damaged bit from service so it does not cause the next failure.
Diagnose slipping while it happens
| Symptom | Likely cause | Immediate action |
|---|---|---|
| Bit spins inside the recess immediately | Wrong profile, undersized bit or debris | Stop, clean the head and test the correct profile and larger adjacent size |
| Bit fits initially, then climbs out | Angled shaft, tilting, low pressure or excessive speed | Release the trigger, realign, reseat and restart slowly with steady pressure |
| Driver stalls before the screw seats | Clutch too low or resistance too high | Check for cross-threading or obstruction; use a pilot hole if appropriate, then raise the clutch only as needed |
| Recess edges look polished or rounded | Cam-out has already begun or the bit is worn | Stop power driving and switch to a fresh, correctly sized bit and hand control |
| Several screws fail in succession | Systematic size/profile error or damaged bit | Replace the bit, verify the fastener standard and review alignment and clutch settings |
What to do when stripping has already started
Stop using the power tool as soon as the recess begins to deform. Try a fresh bit of the correct profile and the largest size that fits, then use a hand driver with the shaft on-axis. Apply steady pressure and turn slowly. If the screw is cross-threaded or encounters abnormal resistance, back it out and correct the alignment or hole before attempting to reinstall it.

Do not keep increasing speed, lean harder on a slipping bit, or pry with a screwdriver. Those actions remove more material from the recess and can damage the surrounding workpiece. A screwdriver is designed to turn a fastener, not to chisel, scrape or lever.
When the recess is fully ruined, use a dedicated extraction method suited to that fastener and workpiece. There is no single extractor technique that is safe for every screw, material or access angle, so select the method only after protecting the surrounding surface and confirming that it matches the situation.
Profile-specific considerations
Phillips and other cross drives
Cross-shaped recesses are especially vulnerable to cam-out when the bit is undersized or the shaft is angled. Keep firm but controlled pressure directly along the axis and use the exact cross-drive standard specified for the screw. If a bit feels loose even though its tip appears similar, treat that as a profile mismatch.
Torx and other high-engagement recesses
Star and specialty recesses can feel secure while still being the wrong size. Test adjacent sizes rather than assuming that a partially engaged bit will transmit full torque. Keep the recess clean so the lobes or points can seat completely.
Tri-point and small electronics fasteners
Small tri-point and similar screws have little material at the recess edges. Use the exact bit, low speed and minimal clutch setting. A hand driver is often preferable for the final turns because it gives earlier warning of rising resistance.
Flathead screws
The blade should fill the slot without being narrower than the slot or so wide that it rides on the surrounding surface. Keep the blade centered and square to the slot; an angled blade twists out easily. Replace a screw whose slot is visibly widened or burred.
Preventive maintenance and storage
- Keep bits dry and clean so corrosion or packed debris does not alter the tip.
- Store profiles and sizes where they can be identified without guessing.
- Retire bits at the first sign of rounding, chipping or bending.
- Check the drill chuck and bit holder for secure engagement before driving.
- Use a consistent low-speed, low-clutch setup for unfamiliar screws, then adjust gradually.
- Keep spare correct-size bits available for jobs where a damaged tip would otherwise be reused.
A quick decision checklist
- Does the bit belong to the screw’s exact profile family?
- Is it the largest size that seats fully and snugly?
- Is the recess clean and undamaged?
- Is the bit straight, sharp-edged and free of chips?
- Is the shaft directly over the screw rather than angled?
- Are you applying continuous, moderate pressure instead of forcing the tool?
- Is the drill starting slowly with a suitable clutch setting?
- Would a pilot hole reduce resistance in this material?
- Have you stopped as soon as the screw became unusually hard to turn?
These checks address the causes that make bits slip: poor fit, poor alignment, uncontrolled torque and avoidable resistance. Torque has no universal safe number because it varies with the fastener, recess, bit condition, tool and material; control the variables you can and stop at the first sign of cam-out.
