E-Z LOK™ Tap - HSS - STI - Bottoming - 4-40
E-Z LOK™ 4-40 STI Tap
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).
- These sturdy taps make large-sized threaded holes to hold helical screw thread inserts.
