M5-0.8 X 8mm 소켓 캡 나사 | 접시머리 육각 소켓 드라이브 | 풀 나사산 | 12.9급 합금강 아연 도금 (600개/팩)

I was pleasantly surprised by the consistent thread quality across all 600 pieces in this pack, which made assembly for my jig much smoother than with cheaper screws I've used before. The zinc plating on these M5-0.8 screws gives them a clean look and seems to resist minor scratches during handling.

I used these to secure a jig on my drill press, and the zinc plating held up well in my humid garage. The flat head design sits flush, which made alignment much easier. Exactly what I needed for light machine work.

The hex socket drive seated perfectly and the 12.9 grade alloy steel feels seriously tough for the price. I used these for a jig build and every single one threaded clean without a single dud in the 600 pack. Exactly what I needed for precision work.
