Key Features & Benefits at a Glance
- Precise fit for 3/8" shafts with controlled ID tolerance (0" to 0.01") ensuring secure placement and reduced vibration in assemblies
- Enhanced load distribution through a 13/16" OD with tight OD tolerance (-0.03" to -0.01") to prevent surface damage and extend component life
- Consistent spacing and alignment maintained by a uniform 0.063" thickness with minimal tolerance variation (-0.003" to 0")
- Robust steel construction delivers high durability and resistance to deformation under heavy-duty industrial loads
- Full environmental compliance with RoHS 3 and REACH regulations, ensuring safe use in regulated markets and eco-conscious projects
- Reliable performance in inch-based systems, designed for seamless integration with standard 3/8" shaft diameters and other imperial components
Professional Applications & Engineering Value
This precision steel washer is engineered to address common industrial challenges such as bolt loosening, surface wear, and assembly misalignment. Its tight dimensional tolerances on ID, OD, and thickness ensure a perfect fit for 3/8" shaft diameters, providing uniform load distribution and reducing stress concentrations in machinery, automotive, and heavy equipment applications. The steel material offers excellent strength and corrosion resistance, while RoHS and REACH compliance makes it suitable for global supply chains requiring environmental safety. Ideal for industrial washers used in high-vibration environments, it enhances longevity and reliability of connected components.
Specification Summary & Compliance
This washer features an ID of 0.377" (tolerance: 0" to 0.01"), OD of 13/16" (tolerance: -0.03" to -0.01"), and thickness of 0.063" (tolerance: -0.003" to 0"), designed specifically for 3/8" shaft diameters in inch-based measurement systems. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring adherence to environmental and safety regulations for industrial use.
