Customer Reviews (4.6 / 5 · 5 reviews)

Riley T. ★★★★★

These little screws have a nice, uniform black finish and the hex drive is crisp—no stripped heads so far. Used them to secure a small jig on my mill and they’ve held tight under moderate load. Solid quality for precision work.

Mia I. ★★★★★

I needed a solid batch of M3 hardware for a jig I’m building, and the black oxide finish looks professional and seems durable. All 600 came neatly packed with consistent threading, and the 15mm length seated perfectly in my fixture plates.

Edward H. ★★★★★

The hex socket drive makes it easy to apply good torque without stripping. These 15mm screws are consistent in length and thread quality, perfect for jig assembly. The black oxide finish is evenly coated and looks durable.
