Ryan ★★★★★

Finally got the box of 2100 and the fully threaded shafts are perfect for the assembly line jigs I run—the class 8.8 steel holds up under constant wrenching without stripping. The hex heads seat cleanly in a socket drive too, so they're quick to spin in. Only wish the pack came with a tray to keep t

Brian ★★★★★

Went through about 300 of these today on a rack build and not a single stripped head or snapped shank. The Class 8.8 steel feels properly tough, and the hex drive seats deep enough that my socket didn't slip once. Full thread all the way up makes them easy to start in tight spots, too.

Carter ★★★★★
