Customer Reviews (5.0 / 5 · 5 reviews)

Amelia ★★★★★

Needed these for a jig I was building, and the hex heads fit my socket perfectly—no rounding or slippage. The yellow zinc coating seems solid, and knowing they're U.S.-made gave me confidence.

Ava ★★★★★

Picked up a pack for a heavy-duty equipment repair and the threads were perfectly clean, no binding at all when I drove them in. The yellow zinc finish looks solid and the hex head gave me a good grip with my socket.

Andrew ★★★★★

Threads were clean, no burrs, and the yellow zinc finish is exactly what I expected for outdoor equipment. They drove in smooth with a socket wrench, so I’ve already used half the pack on a frame jig.
