The Difference Between an STI Tap vs. Standard Tap

At E-Z LOK, we carry a wide selection of high-quality inserts for metal, wood and plastic. Some of these fasteners require help from a specialized tool to install while others only use standard equipment or hand tools. Because of this, two questions we often get from customers are, "what are STI taps?" and "what's the difference between an STI tap vs. standard tap?"

STI (screw thread insert) taps and standard taps both cut threads into a drilled hole. However, screw thread insert taps cut an oversized thread that forms our E-Z Coil™ helical coil inserts into the desired thread size.

Can STI Taps Be Used With Other Inserts?

The short answer is no. STI tap dimensions are designed specifically for use with E_Z Coil™ inserts. Once an STI tap has been used, the threads created are incompatible with Standard Wall or Thin Wall threaded inserts.
