These German made ratcheting T-Handle tap wrenches are made with hardened parallel clamping steel jaws and chrome plating for rust resistance. The “T” handle wrench design allows greater torque and control. A tap wrench is a multi-functional tool. Use in conjunction with the screw extractors for more efficient turning, engagement, and extraction of damaged screws. They can also be used with taps for threading, cleaning threads, and reaming of drilled holes. Imported.
