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

Very disappointed. I am building an RV and have these to hold the wall panels in place. Some of them have rusted in just a few months and will be replaced.

For the restoration of a small park bench with cast iron side profiles joined to wood. You look great. Good big farm heads. I noticed that on two occasions when I replaced the original wood with pressure treated wood the screw heads began to rust. I don't know why, but it's an outside bench and rust does occur.

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.
