Attach Stupid Simple Tools’ Tap Socket Wrench adapter to your 1/4” or 3/8” square drive tool, pop in your thread tap, and let your ratchet wrench, electric screwdriver, or drill do the hard work. Thread holes in seconds without breaking a sweat. Compatible with all number and fractional M.C.T.I. taps up to 3/4". From delicate threads in plastic to hefty threads in steel, this tap socket set is ready for anything. A protective black oxide coating, knurled gripping surface, and internal O-ring combine to protect, grip, and secure your thread taps—even in tight spaces where T-handle tap wrenches can’t go.
