Alexander I. ★★★★★

Couldn’t ask for better threads on these bolts—the 1”-8 threading caught perfectly on my first try with no binding whatsoever. They went right into a pump mounting flange I’ve been fighting with, and the partial threading made alignment so much easier.

Ruby Q. ★★★★★

The threads are clean and the alloy steel feels plenty rigid for the heavy flange work I've got going on. These 1-inch by 6-1/2 inch bolts cut right through the job without any galling, and the package of 25 covered both of my mounts.

Steven A. ★★★★★

These bolts threaded through a flange coupling with no binding, and the partial threading gave just the right grip length for my assembly. The hex heads on these B7s are crisp enough to take full torque without rounding.
