STI Taps for E-Z Coil™ Threaded Inserts
A screw thread insert tap, or STI tap, operates in the same manner as a "standard" tap. However, the difference is that STI taps produce an oversized thread specifically for E-Z Coil™ inserts.
During installation, the threads cut by an STI tap allow the E-Z Coil™ insert to compress and form into the desired thread size, guaranteeing a snug fit. STI taps are ideal for softer metals that require a strong threaded insert.
E-Z LOK’s E-Z Coil™ STI taps are manufactured from high-speed steel (HSS) for superior durability, and we offer them in a wide range of sizes to meet your unique requirements.
