Robert Q. ★★★★★

Ordered these M5x16 hex heads to finish a small aluminum bracket project and the zinc plating looks clean with no burrs on the threads. They torqued down snug without stripping, and for Class 8.8 they feel plenty solid for bench top work.

Leo T. ★★★★★

I've been slowly replacing the mismatched hardware on my drill press jig and these M5x16 hex heads fit perfectly. The zinc plating looks clean and the threads cut smoothly without any galling.

Madison O. ★★★★★

Bought these for a small bench top project and the hex heads take a 8mm wrench without any rounding. The Class 8.8 strength feels solid for the size, and the threads cut cleanly into aluminum.
