M8-1.25 X 100mm 外六角螺絲 | 8.8級鋼本色 | 半牙 (100 / 包)

Used these for mounting a motor bracket to a steel frame, and the hex head gave my socket a solid grip without stripping. The partial threading made alignment easy, and all 100 bolts had consistent quality.

Threaded length is just right for clamping two pieces of steel together with a washer and nut, and the hex heads grab a socket cleanly. These have a solid, hefty feel in hand that gives me confidence they’ll hold up over time. Exactly what I needed for a heavy equipment repair.

I needed some strong bolts for a piece of equipment on my tractor, and these 8.8 grade hex heads fit perfectly with a socket wrench. The 100mm length with partial threading gave me just enough grip without needing a separate washer.
