Professional Applications & Engineering Value
This 5/16" spring lock washer delivers critical engineering solutions where vibration-induced fastener loosening compromises equipment reliability. The 18-8 stainless steel construction provides essential corrosion resistance for applications exposed to moisture, chemicals, or outdoor elements, while the Rockwell C38 hardness ensures the spring lock maintains its tension and locking capability through repeated loading cycles. Engineered with precise inch dimensions (0.807" OD, 0.324" ID), this washer creates optimal interference fit with standard 5/16" screws, making it ideal for industrial machinery, automotive assemblies, and electrical enclosures where maintained clamp load is critical to operational safety and reduced maintenance intervals.
Specification Summary & Compliance
Manufactured to exact inch system specifications with 0.807" outer diameter, 0.324" inner diameter, and controlled thickness between 0.060-0.064". The spring lock washer features 18-8 stainless steel material with Rockwell C38 hardness for consistent mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
