Customer Reviews (4.8 / 5 · 5 reviews)

Ella M. ★★★★★

Needed these for a heavy equipment repair and the Grade L9 alloy steel handled the torque without any issue. The yellow zinc finish arrived clean and consistent across all 25 bolts.

Victoria ★★★★★

The threads engaged cleanly with no binding, and the yellow zinc finish looks like it'll hold up well in my shop. These bolts feel substantial in hand, definitely not your average hardware store grade.

Timothy M. ★★★★★

The yellow zinc finish on these bolts looks great and seems like it'll hold up well against corrosion. Threaded perfectly into my equipment frame without any binding, and the hex head gave me plenty of grip with a socket.
