Customer Reviews (4.6 / 5 · 5 reviews)

Ava H. ★★★★★

The Torx T-15 head seats perfectly in my wrench, so the screw went in straight without any wobble. M4x8 is exactly the size I needed for my tool holder, and it's holding the insert firmly through a few rough passes now.

Olivia ★★★★★

Used these to swap out a chipped insert on my turning tool, and the Torx drive made it effortless to get proper torque without stripping. Each screw threaded cleanly into the M4x8 hole without any binding. They’re exactly what you need for securely holding indexable inserts in place.

Zoe ★★★★★

Fits perfectly in my WNMG inserts, and the M4x8 threads are exactly right. That T-15 Torx head engages solidly without any wobble, which makes swapping out the retaining screw quick and easy.
