M12-1.75 X 20mm 소켓 캡 나사 | 플랫 헤드 육각 소켓 드라이브 | 풀 스레드 | 클래스 10.9 합금강 열처리 블랙 옥사이드 (100개/팩)

Used these for mounting a jig base to a steel table, and the hex socket drive made torquing them down a breeze even in tight spots. The Class 10.9 alloy feels plenty stout for the money, and all 100 came out of the bag without a single burr on the threads.

The black oxide finish on these screws is nice and uniform, and the hex drive fits my wrench perfectly without any slop. They threaded cleanly into a tapped hole for a tooling fixture I'm assembling. Exactly what I needed for this class 10.9 strength requirement.

Used these on a custom jig I’m building and the black oxide finish looks sharp with zero burrs on the threads. The hex socket drive seated perfectly with my driver, and all 100 pieces came sorted clean in the pack.
