Customer Reviews (5.0 / 5 · 5 reviews)

Penelope ★★★★★

These threads are perfectly clean and the partially threaded length gives just the right grip for my hydraulic press rebuild. The B7 alloy feels dense and solid, definitely not cheap hardware.

George V. ★★★★★

I needed heavy-duty bolts for a piece of shop equipment, and these B7 alloy hex cap screws fit the bill perfectly. They threaded smoothly with a tap wrench and held up without any issues under serious torque.

Emma A. ★★★★★

The partially threaded design on these 7/8-9 bolts made alignment a breeze when I was torquing down a heavy pump base, and the alloy steel definitely feels like it can take the punishment. I've bought cheaper fasteners before and regretted it; these are worth every penny for the peace of mind alone.
