Customer Reviews (4.6 / 5 · 5 reviews)

Emma Z. ★★★★★

The hex heads grabbed my 3/4" socket without any slipping, and the zinc plating looks clean and uniform across all 250 pieces. For the price per bolt, having grade 8 strength in this quantity is hard to beat.

Miles M. ★★★★★

Perfect fit for the jig I'm building—the partial threads grab just right without needing extra washers. These Grade 8 bolts feel solid, and the zinc plating looks clean.

Eli ★★★★★

Bought these for a heavy-duty trailer hitch repair and the partially threaded shank made alignment a lot easier than fully threaded bolts. The hex heads grabbed cleanly with a socket and didn't strip under torque. Solid fasteners for the price.
