Customer Reviews (4.8 / 5 · 5 reviews)

Owen ★★★★★

These are perfect for the heavy machinery I'm repairing; the partial threads let me snug them tight without bottoming out on the frame. The zinc coating looks uniform and they drove in with no wobble.

Eli A. ★★★★★

The threads cut cleanly into the steel I was bolting together, and the partial threading gave me just the right grip for a heavy equipment frame. Sixty-five pieces in the pack means I've got spares for the next job without a second order.

Chloe ★★★★★

The hex heads on these bolts have a nice, deep socket fit, and the partial threading made them perfect for clamping down a heavy steel bracket without binding. The zinc coating seems uniform and should hold up well in my shop.
