Black Chrome Plated Steel USS Flat Washers
What are black chrome USS flat washers? Black chrome plated steel USS flat washers are wide-pattern washers with a deep, lustrous black chrome finish over steel. The USS pattern spreads load over a broad surface, and the black chrome plating gives a sleek dark look with better corrosion and wear resistance than black oxide for visible hardware.

What is black chrome plating?
Black chrome is a premium electroplated finish that gives steel a deep, semi-gloss black look with stronger corrosion and wear resistance than black oxide, so a black chrome USS washer suits builds where the hardware is on display and needs a wide bearing surface. It is popular in automotive, motorcycle, and blacked-out assemblies where a bright washer would clash. Because the black is a plating over steel, it is chosen mainly for appearance and light corrosion resistance in indoor and covered use; for wet or coastal exposure, stainless resists corrosion better.
Why choose black chrome USS flat washers
- Deep black finish: sleek, semi-gloss look for visible hardware.
- Wide bearing: USS pattern spreads load over a broad surface.
- More durable than black oxide: harder, more wear- and corrosion-resistant plating.
- Style match: pairs with black or dark-finished hardware.

Black Chrome USS Flat Washers FAQ
Is black chrome the same as black oxide?
No. Black oxide is a thin conversion coating with modest corrosion resistance. Black chrome is a premium electroplated finish with a deeper black look and better corrosion and wear resistance.
Are black chrome washers good outdoors?
They handle light outdoor and covered use as long as the plating is not scratched through. For continuous wet or coastal exposure, choose stainless.
Why a USS pattern in black chrome?
The USS pattern gives a wider bearing surface for larger fasteners and load distribution, combined with the sleek black chrome finish for visible hardware.
