Chenango Supply 1/2 Inch Grade 8 USS Flat Washers – Hardened Alloy Steel, Yellow Zinc Chromate, High-Strength Flat Washers, 50 Pieces (1/2 Flatwasher)

1/2 inch hardened Grade 8 USS flat washers engineered for high-strength fastening applications where load distribution, durability, and dependable performance are required. Specifications Washer type: Flat washer (USS) Size: 1/2 inch Compatible thread: 1/2-13 USS fasteners Grade: Grade 8 hardened Material: Quenched and tempered alloy steel Minimum tensile strength: 150,000 PSI Finish: Yellow chromate zinc coating Quantity: 50 pieces Performance & Application Explanation Grade 8 hardened flat washers are used to distribute load under bolt heads and nuts, helping protect mating surfaces and improve joint stability in high-stress assemblies. The quenched and tempered alloy steel construction delivers the strength required for heavy machinery and automotive applications where standard washers may deform under load. The yellow chromate zinc coating adds corrosion resistance while allowing quick visual identification during installation and inspection. These washers are commonly paired with hardened fasteners in applications where strength and durability are critical to joint performance. B2B Use Cases Commonly used in heavy machinery assembly, automotive repair, equipment fabrication, agricultural machinery, and industrial maintenance applications requiring hardened Grade 8 flat washers. Quality & Trust Reassurance Manufactured from hardened alloy steel with consistent sizing and verified tensile strength to meet professional expectations. Designed for mechanics, fabricators, and maintenance teams who rely on Grade 8 components for critical fastening performance in demanding environments.
