Brian ★★★★★

The hex head grips my socket perfectly without slipping, and the 18/8 stainless steel feels solid for outdoor equipment. These 40mm screws fit my assembly jig exactly, so I didn't have to ream any holes. Exactly the quantity and thread length I needed for the project.

Steven ★★★★★

I needed a full box of 40mm M5s for a jig build, and these stainless hex heads drove in smoothly without any binding. The 18/8 material feels solid, and the 300-count pack is great value for the price.

Lucy E. ★★★★★

The threads are clean and uniform throughout the full length, so they seated perfectly into pre-drilled holes without any binding. Pack of 300 gives me plenty of spares for future projects, and the hex heads take a socket wrench without any slipping.
