Robert ★★★★★

The hex head on these is nice and deep, so my socket grabbed securely without any slipping. They threaded smoothly into a steel bracket I was mounting, and the yellow zinc coating has a clean, even look.

Richard ★★★★★

I needed M8-1.25 x 55mm bolts for a jig I'm building, and these hex head cap screws threaded into the tapped holes perfectly with no binding. The Class 10.9 steel feels solidly heat-treated, and having a full 100 in the pack left me with spares for future projects.

Andrew A. ★★★★★

The yellow zinc coating on these bolts feels nicely uniform, and they threaded smoothly into my equipment frame without any hiccups. For the price of a hundred pack, these M8-1.25s are a solid value.
