  • Oversize taps produce threads that accommodate a screw thread insert

  • Perfect for through-hole applications.

Spiral Point STI taps produce an oversize threaded hole that will accommodate a precision formed screw thread coil of a standard diameter and pitch. Spiral Point taps are rugged free cutting and push chips through the hole. These taps are identified as the size of the internal thread dimensions of the threaded insert.
