Ellie ★★★★★

The black oxide finish on these screws gave them a nice, uniform look right out of the box, and they torqued down cleanly into my tooling plate without any galling. Exactly the consistency I need for a precision assembly I'm prototyping.

Grace ★★★★★

Installed these in a jig for repeat drilling operations and the black oxide finish still looks great after a dozen uses. Hex socket fit snug without any wobble, which is exactly what I needed for precision work.

Emma ★★★★★

I’ve used these cap screws to rebuild a couple of jigs at my shop, and they seat perfectly with no wobble. The black oxide finish added a nice, even coat that resists rust so far. Great fit for precision assemblies without any fuss.
