M6-1 x 120mm 육각 머리 나사 | 8.8급 강철 아연 도금 | 풀 스레드 (100 / 팩)

The hex head on these M6 bolts is nicely formed and grips the socket firmly without any slipping. I used them to secure a heavy machine bracket and the Class 8.8 steel handled the torque without any issues. The zinc plating looks clean and even across all 100 pieces.

The threads are cut perfectly clean all the way down, which made driving them into steel brackets a breeze with a socket wrench. The zinc plating looks uniform and hasn't chipped even after I torqued a few down properly.

Used a handful of these to secure some heavy equipment brackets, and the zinc plating held up well against minor moisture in the shop. The hex heads gave a solid grip with my socket wrench, no stripping issues. Exactly the strength I needed for a clean, permanent hold.
