M8-1.25 X 18mm 육각 헤드 캡 나사 | 316 스테인리스 스틸 | 전체 나사산 (200개/팩)

Needed a handful of these to replace some rusted bolts on a marine fitting, and the 316 stainless steel feels far more robust than the old ones. They threaded smoothly into the pre-tapped holes, and the hex head gave my socket a solid grip for torquing down.

Pulling these M8 bolts tight with a socket, the threads engage cleanly and the 316 stainless feels substantial—no stripped heads so far. Perfect for my marine equipment where corrosion resistance is non-negotiable.

Used a few of these to secure a stainless steel railing I’m building, and the 316 stainless holds up great against weather without any rust. The hex head drives easily with a socket, which saved me time on a tight assembly.
