Adding to our ever growing range are BLACK Stainless Steel Screws. This finish is very useful to reduce light reflection from parts, provide an integrated finish to black coloured products & parts and also for decorative purposes.
It is a conversion coating that produces a uniform, attractive, and non-reflective black finish on stainless steels. The coating reduces friction of moving parts, preventing galling and scoring. Improved corrosion resistance is obtained and there is a negligible dimensional build up, smooth screw assembly is assured.
However, care must be taken to select the right conditions under which Black Stainless Steel Fasteners should be used. It is not recommended for all applications.
Colour will change if you’re using black oxide and a 900 degree or higher environment. So if you’re going to put the black oxide parts into nine hundred, one thousand degrees, you’re going to see variations in the colour happen.
Further, if an SS-304 Black coated fastener is exposed to salt, you will see Red Rust because of the coating.
Red Rust formation on the Black Oxide layer can be noticed in many harsh environments although this can be washed off as the properties of the base material – Stainless Steel – will still work.

It’s interesting to know that there will be variations in the color of the material when you apply black oxide finish products at 900 to 1,000 degrees of temperature. I can imagine how important it is for those planning to get those kinds of services to find someone who is an expert and experienced in that industry. They can give them the assurance that there will be no discoloration once the project is done if that is not what they have requested.
nice to see black stainless steel range . a very new concept for me too see
Thanks for thr great article!
Informative and well written post
It is very comforting to see that others are facing from the same problem as you. Good solution!
