Customer Reviews (4.8 / 5 · 5 reviews)

Ruby U. ★★★★★

Was pleasantly surprised by the consistent thread finish across all 400 screws—no burs or rough spots. They seated perfectly in my tooling jig without any wobble.

Violet ★★★★★

Exactly what I needed for rebuilding a jig fixture at work. These M4 x 40mm button heads came fully threaded and the zinc plating looks uniform across all 400 pieces. The 12.9 alloy steel feels seriously solid, and the hex socket drive bit seated perfectly every time.

Julian ★★★★★

The hex socket drive on these 12.9 alloy steel screws fits my drivers perfectly, making assembly on my jigs much smoother. The zinc plating also looks clean and consistent across all 400 pieces—no defects so far.
