Customer Reviews (4.6 / 5 · 5 reviews)

Riley ★★★★★

I needed some heavy-duty bolts for a press repair job, and these fully threaded M27s held up perfectly under full torque without any stripping. The class 8.8 steel is noticeably denser than the hardware store stuff, and the hex head gave my socket wrench a solid grip each time.

Amelia ★★★★★

I needed some heavy-duty fasteners for a machine base plate, and these M27-3 x 120mm cap screws held up perfectly under torque. The hex head gave my socket a solid grip without any slipping.

Matthew ★★★★★

The threading is clean and uniform across the full 120mm length, which made torquing them into my equipment housing a breeze with a socket. Class 8.8 steel feels plenty sturdy for the heavy-duty assembly I needed them for, and the hex head gave a solid grip without slipping.
