Customer Reviews (4.6 / 5 · 5 reviews)

Hannah ★★★★★

I was kind of skeptical about paying more for bolts but these threaded cleanly into an old machine base without any binding. The hex head gave my socket a solid grip and the coating looks like it will hold up well.

Hazel R. ★★★★★

These L9 bolts are noticeably harder than the standard hardware store stuff I've been using, and the hex heads mach my socket perfectly. They snugged down on my press table with no stripping or deformation. Exactly what you need for heavy equipment.

Jason ★★★★★

Threaded all the way down, these bolts grabbed evenly from the start and held tight on my press frame. The yellow zinc coating looks quality too, no flaking after a week of use.
