I needed a few extras for a tooling fixture and these hex socket screws seated perfectly without any stripping. The 1/4-28 threads engaged smoothly, and the thermal black oxide seems like it'll hold up well.

The black oxide finish on these screws gave my tooling jig a clean, professional look, and the hex drive seated perfectly without stripping. They're solid enough for precision assemblies.

The black oxide finish on these 1/4-28 screws is exactly what I needed for a jig build—they thread smoothly without binding. The hex socket drive made installation in tight spots a breeze.
