xDetailed Description:
USS Grade 8 Yellow Zinc Plated Flat Washers are high-strength components designed to distribute the load of threaded fasteners, such as bolts and nuts, over a larger surface area. Manufactured from through-hardened Grade 8 steel, these washers offer a Rockwell hardness of C38–45, ensuring durability and resistance to deformation under high stress. The yellow zinc plating provides corrosion resistance, making them suitable for various environments.
Key Features:
-
Material: Through-hardened Grade 8 steel.
-
Finish: Yellow zinc plating for corrosion resistance.
-
Hardness: Rockwell C38–45.
-
Standards: Conforms to ASME B18.21.1 Type A Wide Series and ASTM F436 specifications.
-
Applications: Ideal for use with Grade 8 bolts and nuts in high-stress applications where load distribution and corrosion resistance are critical.
These washers are commonly used in automotive, industrial, and structural applications where high strength and reliability are required.
