Whether you want the high tech look of exposed flat black screw heads, or just don’t want to bother with countersinking, but don’t want to see a shiny screw head, these black oxide plated screws will be just the ticket. Black Oxide offers very little corrosion resistance though, so use in humid environments, wood with a high moisture content, or highly acidic woods like oak may result in some discoloration. For reference purposes, this finish is used on most socket head cap screws and other automotive style machine screws. Available in Combo Recess only. Made in US/Canada/Taiwan. #1 Square Recess.
NOTE: Black Oxide coating does not result in a true solid black color, but may result in a slight bronze or copper color showing through the black oxidation.

About Me Casual Do-It-Yourselfer
Since I am 82 years old it is hard to manage projects that call for both hands, With these square drive units I can start the screw easily with one hand, and achieve a good looking finished product. I use all square drive for repair and maintenance projects.
These are as good as it gets
I keep ordering...over and over...they are perfect for what I use them for
