M12-1.75 x 65mm 육각 머리 볼트 | 클래스 10.9 강재 아연 도금 | 부분 나사산 (50개/팩)

The zinc plating is holding up nicely under the shop’s humidity, and the hex heads gripped the socket without any slippage during install. These 65mm partially threaded bolts seated perfectly for a heavy equipment bracket I’m rebuilding.

I needed a full box of these for a machinery build and the partially threaded design bit in perfectly, leaving just enough thread for the locking nut. The hex heads are crisp, so my socket hasn't slipped once across fifty installs.

Zinc plating looks clean and even across all fifty pieces, and the hex heads seated perfectly in my socket wrench without any stripping. These M12s did the job for a heavy equipment frame I'm rebuilding, and the class 10.9 strength gives me real confidence under load.
