Professional Applications & Engineering Value
This precision steel washer is engineered to address common assembly challenges in industrial settings, such as component wear, bolt loosening, and surface damage. Its 0.3145" ID is optimized for 5/16" shaft applications, providing a snug fit that minimizes play and distributes clamping force evenly. The steel material offers high strength and corrosion resistance, making it suitable for heavy-duty washers in machinery, automotive, and construction equipment. With controlled tolerances on ID, OD, and thickness, it ensures repeatable performance in high-vibration environments, reducing maintenance needs and enhancing the longevity of connected parts. The RoHS and REACH compliance further supports its use in environmentally conscious manufacturing and global supply chains.
Specification Summary & Compliance
This washer features an ID of 0.3145" (tolerance: 0" to 0.01"), OD of 0.75" (tolerance: -0.03" to -0.01"), and thickness of 0.032" (tolerance: -0.002" to 0"), designed for 5/16" shaft diameters in inch measurement systems. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial components.
