Professional Applications & Engineering Value
Engineered for precision industrial washers applications, these steel flat washers solve critical vibration and surface pressure challenges in 1/4" shaft assemblies. The inch system manufacturing with controlled tolerance ranges prevents bolt loosening and component wear in automotive, machinery, and electrical enclosures. The RoHS compliant and REACH compliant steel material ensures corrosion resistance and environmental safety without compromising the mechanical strength needed for heavy-duty washers operations. This combination of precise dimensions and regulatory adherence makes them ideal for OEMs and MRO professionals requiring reliable, specification-grade precision washers.
Specification Summary & Compliance
This steel washer maintains inch-based dimensional accuracy with ID tolerance of 0" to 0.01", OD tolerance of -0.03" to -0.01", and thickness tolerance of -0.002" to 0". Manufactured for standard 1/4" shaft diameter applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and substance restriction requirements for industrial components.
