Customer Reviews (4.8 / 5 · 5 reviews)

Violet ★★★★★

I needed a solid batch for a jig project and these black oxide M4 screws definitely deliver. The hex socket drive bit seats perfectly and the threads run smooth without binding—even in tight production fittings.

Eli T. ★★★★★

The threading is clean and uniform across all 400 pieces, and the black oxide finish looks consistent even under bright shop light. I grabbed a handful for a jig I’m building and they seated flush without any binding. Solid purchase for the price.

Aurora ★★★★★

The hex socket drive grips perfectly with my Allen key, and the 12.9 alloy steel feels rock solid threading into my jig fixture. Took all 400 without a single stripped head, which is exactly what I needed for a tight production run.
