Eva N. ★★★★★

I needed a solid batch for a custom jig I've been building, and the black oxide finish on these M8-1.25 screws is holding up well against minor scratches. The fully threaded shaft gave me plenty of grip in my steel fixture.

Mia ★★★★★

These M8-1.25 x 18mm screws threaded cleanly into my jig fixture without any binding. The hex socket drive held up well under repeated use with my torque wrench. Exactly what I needed for heavy-duty tooling.

Emily H. ★★★★★

The black oxide finish on these M8 socket screws looks professional and resists wear well. I used them for jig assembly and the hex drive made installation smooth with no stripping. A solid buy for precision work.
