Customer Reviews (4.8 / 5 · 5 reviews)

Stella ★★★★★

Threads cut clean and the hex heads grabbed my wrench without any rounding. These are solidly built, and the partial threading gave me plenty of grip for the steel frame I bolted together.

Stella R. ★★★★★

Installed these on a big equipment frame and the 1"-8 thread bit into the steel cleanly. The partial threading made it easy to snug down the nut without fighting the whole shaft. USA-made quality that feels solid.

Violet X. ★★★★★

Threads were clean and the partial threading grabbed perfectly when I bolted a jig frame together. Hex heads seated without stripping, and all fifteen had consistent plating. Solid buy for industrial work.
