Customer Reviews (4.6 / 5 · 5 reviews)

Nicholas X. ★★★★★

I was a bit nervous about ordering such a heavy fastener online, but the threads are clean and the partially threaded length is exactly right for my equipment jig. These B7s have that solid, substantial weight you want when torquing down something that can't afford to fail.

Edward D. ★★★★★

The threads are clean and sharp right out of the box, which made starting them by hand a breeze. Used a set to secure a heavy press base and they torqued down evenly without any galling.

Harper T. ★★★★★

These bolts arrived well-packaged and the partially threaded design made seating them in my equipment frame much easier than fully threaded ones. The B7 alloy steel feels substantial and should hold up fine under the load I need them for.
