Customer Reviews (4.6 / 5 · 5 reviews)

Brian P. ★★★★★

Threads were clean and the hex head seated perfectly with my 30mm socket, no wobble on a heavy jig I bolted down this week. These are seriously stout for the price, and having two in the pack meant I could spare one for a backup.

Henry S. ★★★★★

The partially threaded design made these perfect for mounting a heavy gearbox where I needed a smooth shank through the housing. They torqued down nicely with a socket wrench, and the class 10.9 steel feels seriously robust.

Chloe ★★★★★

I needed a strong bolt for a heavy machinery repair, and these hex head cap screws handled the torque perfectly. The 10.9 steel feels solid, and the partial threading made alignment much easier. Fast shipping too.
