Detailed Description

Black Oxide Stainless Benefits:

  • Our Stainless steel black oxide screws and fasteners are coated locally here in the USA.
  • Our Black oxide is most useful for application where the corrosion resistance and durability of stainless is necessary, but costmeticall, a black finish is needed.
  • The black oxide is applied to 18-8 and A2 Stainless fasteners but can be applied to any grade of stainless or alloy.
  • We black oxide and wax our plain stainless screws and nuts, which created a black satin finish
  • The wax is invisible but adds a slight amount of additional corrosion resistance to the already resistant stainless steel.
  • The black oxide looks very sharp and allows the customer to use stainless even though they really need to use a black fastener.
  • Prior to this black oxide process becoming an off the shelf option for stainless fasteners, customers had to chose between silver stainless, or alloy steel black.


If you do not see the black oxide screw, nut or washer you are looking for, please contact us as we are more than happy to work with you on a custom black oxide fastener.
