Black Oxide Stainless Steel Screws & Bolts
Matte Black Finish with Corrosion-Resistant Stainless Steel Core
Black oxide stainless steel fasteners combine the superior corrosion resistance of stainless steel with a sleek, low-reflective matte black finish. Popular in automotive, electronics, architecture, and tactical applications, these fasteners offer both form and function. They’re often used when you need the strength of stainless with a more discreet or modern appearance.
What is Black Oxide Coating?
Black oxide is a conversion coating applied to stainless steel fasteners that enhances corrosion resistance while providing a smooth black appearance. Unlike paint or plating, it won't chip or flake off. The finish also reduces glare, improves lubricity, and helps prevent galling in threaded applications.
Why Choose Black Oxide Stainless Fasteners?
- Non-Reflective Appearance: Ideal for visible or design-sensitive installations like electronics, signage, and tactical gear.
- Corrosion Resistance: Retains the natural resistance of stainless steel, making it suitable for indoor or mild outdoor use.
- Durability: The oxide finish integrates into the metal surface, offering long-lasting performance without peeling or cracking.
- Functionality: Maintains standard thread tolerances and is compatible with existing stainless steel hardware.

FAQs
Are black oxide stainless fasteners fully corrosion-proof?
While black oxide adds protection, the base stainless steel is what delivers corrosion resistance. These fasteners are best for dry or mildly corrosive environments.
Will the black oxide wear off?
Black oxide is a conversion coating, so it’s integrated into the metal and won't flake. However, heavy abrasion or repeated use may cause fading over time.
Can I use these fasteners outdoors?
Yes, but they perform best in covered or dry outdoor environments. For marine or coastal areas, consider 316 stainless fasteners without black oxide for maximum protection.
