Hannah ★★★★★

These fit perfectly on my 3/8" shank Warner grooving tool. I like that they're retaining screws, so I don't have to worry about them backing out during a cut.

Abigail S. ★★★★★

Needed a replacement for my grooving tool and this 6-32 x 3/8" cap screw was an exact match—threaded in smoothly without any forcing. Nice to have a properly sized retaining screw that stays put during heavy use.

George ★★★★★

Worked perfectly to secure the retaining screw on my Warner cut-off tool—the 6-32 threads matched exactly.
