E-Z LOK™ Tap - HSS - STI - Bottoming - 4-40

Product Description

Unlike “standard” taps, E-Z LOK™ STI taps create large, oversized threads that are specifically meant for E-Z Coil™ threaded inserts.

When installing the insert, the threads that are cut by the 4-40 STI tap fit the E-Z Coil™ insert into the specific thread size. These unique taps are ideal for tapping holes in soft metals that require robust threaded inserts.

The 4-40 STI tap is designed for long-lasting durability and is made out of high speed steel (HSS).
