• Durable steel construction provides excellent strength and resistance to deformation under high stress.
• Full RoHS 3 and REACH compliance assures safe use in regulated environments and global market access.
• Optimized 0.032" thickness offers a reliable spacer function without adding unnecessary bulk to the assembly.
• Ideal for heavy-duty applications where reliability and environmental standards are critical.

Professional Applications & Engineering Value

This precision steel washer is engineered to solve critical challenges in industrial machinery and mechanical systems. Its specific 0.627" ID is designed for a perfect fit on 5/8" shaft diameters, eliminating play and reducing wear on mating surfaces. The robust steel material ensures it can withstand high compressive loads, preventing fastener loosening and component damage. The tight inch-based tolerances on the ID, OD, and thickness guarantee that every washer performs consistently in automated or high-volume assembly lines, reducing downtime and maintenance costs. This makes it an indispensable component for heavy-duty applications in automotive, manufacturing, and construction equipment where RoHS and REACH compliance is mandatory for environmental safety and supply chain compliance.
