The hex socket drive fits my driver bits perfectly, and the black oxide finish on these screws has a nice, even look. Used them to secure a bracket on a small fixture, and they threaded in smoothly without any binding.

Put these in a jig I’m building and the black oxide finish makes them much easier to see against the metal plate. The hex socket drives cleanly without cam-out, which is a relief for such small fasteners.

Finally found exactly the nylon pellet socket cap screws I needed for a jig I'm building, and the #5-40 x 1/4" size fits my threaded inserts perfectly. The black oxide finish looks clean and should hold up well.
