Christopher ★★★★★

Grabbed a box for a trailer hitch build and every single one seated perfectly with a standard socket. The hex heads have solid bite and the yellow zinc finish seems like it'll hold up fine in the shop.

Timothy ★★★★★

The threads cut clean and the yellow zinc finish looks uniform across all 350 pieces, which matters when you’re torquing them down on a jig. I’ve already used about two dozen for a frame assembly and the hex heads grab a socket without any wobble.

Harper ★★★★★

I needed a full box of these for a heavy equipment repair and the fully threaded design made installation quick. The hex heads fit my socket perfectly and the yellow zinc finish looks like it will resist rust well.
