Harper ★★★★★

I used these to repair a jig on my milling machine and the 316 stainless holds up perfectly against coolant splashes. The hex socket drive made installation quick with no rounding issues.

Brian ★★★★★

The partial threading is perfect for pulling two metal plates together snugly without the threads chewing up the bore, and the 316 stainless finish has kept them spotless around my shop's humid corner. I ordered a second pack the same day I got these.

Julian ★★★★★

Installed these on a marine railing repair and the 316 stainless is already holding up better than my old hardware did near saltwater. The partial threading gave just the right grip depth for the wood-to-metal joint.
