Professional Applications & Engineering Value

This 18-8 stainless steel split lock washer addresses critical vibration-induced loosening challenges in industrial fastening systems. The standard split lock washer type creates continuous spring tension against both bearing surfaces, maintaining clamp load where conventional flat washers fail. Engineered specifically for No. 6 screw size applications, the precise 0.148" internal diameter ensures proper seating while the 0.266" outer diameter provides optimal load distribution. The Rockwell C35 hardness delivers the perfect balance between flexibility and strength, allowing the washer to maintain its locking action through thermal cycling and mechanical stress. Ideal for industrial washers applications in machinery, electrical enclosures, and transportation equipment where vibration resistant fastening is essential for safety and reliability.

Specification Summary & Compliance

This split lock washer features precise inch system dimensions: 0.148" internal diameter, 0.266" outer diameter, and 0.040" thickness specifically engineered for No. 6 screw applications. Manufactured to ASME B18.21.1 specifications for standard lock washers, ensuring dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, meeting the latest environmental standards for industrial components.
