Proto J69X00 Bolt Extractor Socket Set

The Proto bolt/stud/screw extractor set makes it easy to remove rusted, rounded, or damaged nuts and bolts. Use in combination with other drive tools (ratchets, adjustable wrenches, sockets, or combination wrenches) to help reach fasteners in difficult locations. Each working end has a helical shaped flute that helps grip rounded fasteners, round head bolts, and pan head screws. Use on SAE or metric fasteners. Through-hole design allows access to fasteners at the end of long bolts or studs.
