M3-0.5 X 30mm 소켓 캡 나사 | 버튼 헤드 육각 소켓 드라이브 | 전체 나사산 | 12.9급 합금강 아연 도금 (600 / 팩)

These M3 screws have a clean, uniform thread all the way along the 30mm shaft, making them perfect for my jig assembly. The hex socket drive fits my Allen key snugly without any wobble, and the zinc coating gives them a nice, even finish. I’ve already ordered another pack for future projects.

Finally got around to replacing the worn fasteners on my jig, and these 12.9 alloy steel screws feel seriously solid—the zinc plating took a few scuffs without a hint of rust. The hex socket drive bites cleanly, no stripped heads even with a cheap driver; 600 pieces means I won’t run dry for a while

Needed a batch of M3 screws for a small CNC fixture build, and these worked perfectly. The hex socket drive bit into the driver cleanly without any cam-out, and the zinc plating looked consistent on every single one of the 600.
