Sentry Supply 650-7905 One Way Screw Remover and Driver Multi-Bit Tool, Black and red

If you are searching for one-way fastener installation and removal driver bits, you have just found them. One-way, tamper-resistant screws are manufactured with heads that only allow for forward driving, or sinking of the threaded shafts, where regular flat-head screw drivers slide off when attempting to reverse and remove them. This tool set includes a one-way screwdriver bit, and a one-way remover bit. Each are constructed of hardened steel material and allow for high torque driving or extracting of one-way security fasteners. These bits can be used in hand-held driver handles, cordless and corded drills that can hold 1/4 inch shanks. Order yours today.
