How do I remove a small broken screw without an extractor?
Place a wide band rubber band flat in between the screw driver (we recommend bumping one size up from the screw head which caused the strip) and the screw, then apply hard, but slow force while turning the screw. If you’re fortunate, the rubber band will fill in the gaps caused by the strip and allow extraction.
Why do screw heads break off?
By drilling a pilot hole in the wood, you’re removing some wood to make space for the screw. Without a pilot hole, the screw is essentially wedging itself into the wood. This puts a lot more pressure on the screw as well as the wood. In weak woods, this can cause a split; with weak screws, the screw can break.
Do impact drivers break screws?
Of course today’s impact drivers are way overpowered for any small screws, a 12v will easily sink a 3″ screw whereas a 18v will quickly break either the bit, the screw, or wood. Whoever is cracking the screws just need to get used to impact driver and not use the same technique as using a drill.

#1 make sure that your pilot hole is deeper that the tapcon. #2 run the bit up and down in the hole a few times to clean it out. # 3 double check the size of your bit and make sure the edges have not broken off and made the diameter smaller.
Can Tapcons be removed and reinstalled?
The holding values of a masonry screw that is removed and then reinstalled in the same hole will have less to zero holding values. The removal and reinstalling process may cause the tapped threads in the base material to deteriorate, which affects the holding values of the masonry screw.
Can you reuse a self tapping screw in the same hole?
