M2.5-0.45 x 6mm 소켓 캡 나사 | 육각 소켓 드라이브 | 풀 스레드 | 클래스 12.9 합금강 아연 도금 (600개/팩)

Zinc plating’s holding up well after a few weeks in my shop, and the hex sockets are cut cleanly enough that my hex keys seat firmly every time. For the price per piece, you really can’t beat the consistency across the whole 600-count bag.

I needed a reliable batch for a jig I’m building, and these little hex socket screws are consistently tough and easy to drive with a hex key. The zinc plating on the 12.9 alloy steel looks clean and should resist rust well in my shop.

Machine work finally feels less like a battle with these 12.9 alloy steel screws—no more rounding out the hex socket on tight spots. The zinc plating keeps them slick even after a few months in my tool cabinet. Ordered the 600 pack and already planning the next project around them.
