Customer Reviews (4.8 / 5 · 5 reviews)

Eli D. ★★★★★

Put these on a heavy-duty trailer hitch build and the grade 8 hardness made torquing them down to spec feel solid. The partial threading was just right for clamping the spring plates without bottoming out.

William ★★★★★

These hex heads grabbed cleanly with my socket wrench, and the 5-1/2" length was just what I needed for a heavy machinery repair. They feel solid and the partial threading helped seat them perfectly against the frame.

Joseph K. ★★★★★

The zinc plating on these grade 8 bolts looks clean and even, and they threaded smoothly into my ag equipment without any binding. I used a socket for the hex head and it gripped perfectly.
