Adam J. ★★★★★

I needed a batch of small screws for a jig I'm building, and these M3-0.5 x 16mm ones fit perfectly with their fully threaded design. The zinc plating looks clean and even, and the hex socket drive made them easy to tighten without stripping.

Penelope I. ★★★★★

The hex socket drive on these M3 screws grabbed my driver perfectly without any cam-out, and the zinc coating feels durable. I used them to rebuild a jig fixture at work and every single one threaded smoothly into the tapped holes.

Nicholas S. ★★★★★

Finally, a batch of M3 screws with threads that actually match the spec consistently from end to end. The zinc plating seems uniform across all 600 pieces, which makes a big difference for my jig builds. Ample length for gripping into 3mm plates without bottoming out.
