M12-1.75 x 170mm 六角頭螺絲 | 等級8.8鋼 無處理 | 部分螺紋 (25個/包)

Used these on a heavy equipment repair job and the hex head held up nicely under torque with a socket wrench. The 8.8 steel feels solid and the partial threading made alignment much easier.

The partial threading on these 170mm M12s made aligning them in my equipment mounts a lot easier, and the Class 8.8 steel feels properly solid under a wrench. Pack of 25 at this length is a decent value for the shop.

The hex head on these M12 screws gave my socket wrench a solid grip, making installation smooth. The 170mm length was just right for the heavy equipment frame I was bolting together.
