Washers

Washers are essential mechanical components used in bolting assemblies to distribute the load of a threaded fastener, prevent damage to the mating surface, and, in the case of spring or lock washers, prevent loosening due to vibration. Zeron Fasteners manufactures a comprehensive range of industrial washers, including Flat, Lock, and Spring types, using materials engineered for extreme conditions. Our materials range from high-hardness Alloy Steels (matched to B7/B16 bolts) to highly corrosion-resistant alloys like Hastelloy, Inconel, and Duplex steel, ensuring the integrity and lifespan of critical flanged joints in petrochemical, marine, and power generation sectors.
