Screw, Insert Retaining, IS 3007

The T-9 Torx wrench that comes with it is a nice touch—saves me from digging through my toolbox every time I swap inserts. Threads seated cleanly and locked down tight on my holder without any wobble.

This Torx screw fits perfectly into my Warner tool holder, and the threads are clean enough that I don’t have to force it. The chart on the listing made it easy to confirm it’s the right size before buying.

I’ve been using this insert retaining screw for a few weeks now with my Arthur R. Warner turning tools, and the T-9 Torx drive hasn’t stripped at all during multiple changes. Good snug fit, no wobble.
