Customer Reviews (4.4 / 5 · 5 reviews)

James ★★★★★

The PFC9 alloy steel feels seriously tough, and the yellow zinc coating looks like it'll shrug off corrosion in the shop. Drove a few into a jig today and the hex heads seated perfectly with a socket, no stripping or wobble. For 20 pieces at this quality, you can't beat the price.

Abigail H. ★★★★★

Used these to secure a heavy press at work, and the PFC9 alloy steel threads cut clean without any binding. The yellow zinc coating looks solid and hasn't shown any rust after a few weeks in a damp shop.

Ryan ★★★★☆

Picked up these hex bolts for rebuilding a conveyor section; the threads were clean and started easily by hand. The yellow zinc coating looks nice and tough, though the price is a little steep for a four-inch bolt. Still, they feel solid and haven't stripped under torque.
