M3-0.5 X 16mm 소켓 캡 나사 | 육각 소켓 드라이브 | 전체 나사산 | 클래스 12.9 합금강 아연 도금 (600개/팩)

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.

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.

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.
