For applications requiring maximum strength and the traditional, highest level of corrosion protection, FMW Fasteners presents our Extra Heavy Flat Washers, featuring the classic Yellow Zinc Chromate (CR+6) finish. Sourced exclusively from domestic USA manufacturers, these washers are built to extreme standards for non-standard, heavy-duty applications.
Our Extra Heavy Flat Washers are substantially thicker and larger than standard washers, designed to distribute massive loads across a wider area, making them ideal for oversized holes or extreme pressure environments.
Key features of this product category:
-
Exceptional Durability: The Extra Heavy thickness ensures maximum stability and load-bearing capacity under severe stress.
-
Superior Hexavalent Chromium (CR+6) Finish: The Yellow Zinc CR+6 chromate coating offers unparalleled resistance to white and red rust, featuring a self-healing property for minor scratches that is highly valued in demanding, non-RoHS-restricted industrial environments.
-
Aesthetic & Identification: The distinctive yellow-gold, iridescent color is not only a cosmetic appeal but a visual indicator of this highly protective finish.
-
Domestic Quality: Manufactured in the USA, you receive a premium, traceable product that meets the stringent quality control standards required for heavy construction, large machinery, and specialized projects.
These washers are typically used in:
-
Heavy machinery and industrial equipment assembly
-
Oversized or slotted holes where standard washers are insufficient
-
Repair, maintenance, and operations (MRO) in non-RoHS regulated industries
-
Specific defense or legacy automotive applications requiring the original CR+6 standard
When only the strongest, most corrosion-resistant, domestically-produced Extra Heavy Yellow Zinc CR+6 Washers will suffice, choose FMW Fasteners.
