A stripped screw usually gets worse when the same slipping driver is used repeatedly. Start with the least aggressive approach—correct bit, straight pressure, and extra grip—and escalate only when necessary so the workpiece and screw are not damaged further.
Use the exact driver bit and straight pressure
Clean the screw head and use a bit that fills the recess properly. Keep the driver aligned with the screw axis and press firmly while turning slowly; an undersized bit will round off what remains.
Add grip before drilling
A thin rubber band between the bit and head can help with light damage, and locking pliers may work if enough of the head protrudes. Avoid high-force tricks near fragile surfaces or electrical components.
A screw extractor requires centered drilling
For heavier damage, a screw extractor works best with a small, centered pilot hole sized according to its instructions. Drilling off-center can damage the threaded part or break the extractor, which is difficult to remove.
Stop if the screw belongs to a critical component
Screws in electrical panels, energized appliances, structural hardware, or safety-critical assemblies are poor places to experiment with drilling and extraction. Isolate power and use the appropriate service procedure when needed.
