Professional Applications & Engineering Value

This 18-8 stainless steel clipped washer is engineered to address common industrial challenges such as corrosion in humid or chemical-exposed settings and vibration-induced fastener failure. The clipped design allows for efficient installation in confined areas or along edges, reducing labor time in assembly lines and machinery maintenance. Its Rockwell B68 hardness ensures it maintains integrity under repetitive stress, while the inch-system dimensions provide exact compatibility with 9/16" screws in heavy-duty equipment, construction frameworks, and transportation systems. By combining corrosion-resistant properties with a robust build, it extends service life and minimizes downtime in demanding applications.

Specification Summary & Compliance

This washer features precise inch-system dimensions: ID 0.594", OD 1.5", and thickness range 0.084-0.097", with a clipped width of 1.275" for compatibility with 9/16" screws. Manufactured from 18-8 stainless steel and hardened to Rockwell B68, it adheres to standard industrial tolerances. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety requirements for global supply chains.
