You anchor the bell over the face of the lock, thread a screw into the keyway or the plug face, then wind the puller down so it pulls the plug forward against the housing. Standard wood or machine screws strip, slip, or snap under that load. They were never made for it.\u003c\/p\u003e\n    \u003cp\u003eLokko pull screws are. The self-tapping point cuts its own thread as it goes, the aggressive thread geometry holds its grip while you crank, and the high tensile strength means the screw survives the pull instead of shearing inside the cylinder. That is the whole job: a screw that bites and stays bitten, so the puller can do its work on bypass and forced-entry openings, lock removals, and disassembly jobs where the key is gone.\u003c\/p\u003e\n    \u003cdiv class=\"sts-grid\"\u003e\n      \u003cdiv class=\"sts-card\"\u003e\n\u003ch4\u003eSelf-tapping\u003c\/h4\u003e\n\u003cp\u003eThe point cuts its own thread, so no pre-drilling is needed.
