Review on 🔩 High-Quality B18 6 3 Machine Finish Phillips Threaded Fasteners for Superior Screw Performance by Eric Chapman

I wanted the black screw to be a bit more subtle than the stainless steel screw, but the inside of the screw head (wear on screwdriver bits) also doesn't have a black finish. This uncoated part of the screw rusted through completely in just 2 days. They are perfectly finished and the dimensions correspond perfectly to the description, but I would like the inside of the head to be treated to avoid rust. Now I have a nice black screw with a bright orange head.
