James ★★★★★

I was relieved the black oxide coating matched my existing hardware perfectly, which saved me from having to paint them. These M6 screws seat firmly with a hex key and the 20mm length is ideal for securing medium-thick bracket assemblies.

Richard I. ★★★★★

Bought these for a fixture jig I’m building, and the black oxide finish looks like it’ll hold up well in the shop. The hex drive seated without any stripping or binding.

Aurora S. ★★★★★

The flat head sits flush in the countersink like it’s supposed to, and the black oxide finish looks clean on my jig. Pulled them down tight with a torque wrench and not a single one stripped or rounded out.
