SAE Washers (Thru Hardened) - Material Options
South Coast Fasteners stocks flat washers (thru-hardened) in medium carbon steel that has been heat-treated for strength, durability, and long-term reliability in structural connections.
Medium Carbon Thru-Hardened Steel (Imported)
Medium carbon thru-hardened steel washers are built to resist crushing and deformation when paired with high-strength bolts. The heat treatment process increases hardness and wear resistance, ensuring the washer can stand up to heavy loads without giving way. Imported versions provide a cost-effective option while still delivering the toughness and consistency required in structural framing, heavy equipment, and industrial assembly.
SAE Washers (Thru Hardened) - Available Finishes
South Coast Fasteners offers flat washers (thru-hardened) in finishes that protect against corrosion, extend service life, and fit the needs of different environments.
Plain
Plain finish washers are uncoated and best suited for dry indoor environments or shop work where corrosion is not a concern. They are also ideal when a custom coating, paint, or welding process will be applied after installation. Simple, adaptable, and economical, plain finish washers remain a versatile choice across industries.
Yellow Zinc Cr+6
Yellow zinc Cr+6 provides a golden finish that combines corrosion resistance with easy visibility. This coating protects washers from rust while giving them a bright, professional appearance. Contractors often choose yellow zinc for jobs where both performance and identification matter, such as industrial equipment, structural steel, or automotive work.
Zinc Cr+3
Zinc Cr+3 is a widely used protective finish that provides a bright, clean appearance along with dependable resistance to rust and wear. It extends the service life of washers and fasteners by forming a thin but durable coating over the base material. Contractors favor this finish for indoor and light commercial applications where cost efficiency and consistent performance are important. Its combination of corrosion resistance, affordability, and professional look makes it one of the most commonly specified coatings in the industry.
