The hexagonal flat can also be used with flat wrenches, adjustable wrenches, sockets, and locking pliers. Its compact design allows access into small areas, where studs may be hard to reach. Manufactured with high-grade Heat-Treated Alloy Steel for maximum durability, this tool also features a chrome finish for additional rust protection. MULTIPLE USES: This tool will save hours of frustration on broken exhaust manifolds, oil filler plugs, rounded starter bolts, low grade bolts left in saltwater, painted-over bolts, rusted tight bolts and more. TRADITIONAL BOLT EXTRACTORS: Traditional bolt extractors force the user to guess which size the damaged stud is. They have a tendency to strip the screw even more and shave metal off without budging the screw, leaving you worse off than when you started. The universal design of this tool allows you to clamp down on the damaged stud, eliminating the guess work. RELIABLE | EFFECTIVE | EFFICIENT: Users trust ARES to be quality tools.
