Remove broken bolts, stripped screws, and seized fasteners with this 6-piece coarse thread screw extractor set from 177Tools. Each extractor features a reverse spiral flute design that bites into the damaged fastener as you turn counterclockwise — the harder you turn, the tighter it grips.
Made from hardened chrome-vanadium steel with a black oxide finish, these extractors are built to handle tough jobs in auto repair, machinery maintenance, and industrial equipment service. The set covers a range of bolt and screw sizes and comes in a compact storage case.
Includes:
6 extractors in graduated sizes
Durable storage case with size markings
Compatible with standard drill chucks and tap wrenches
