Professional Applications & Engineering Value
This steel split lock washer delivers critical vibration-resistant performance for industrial applications where fastener security is paramount. Engineered with precision dimensions (0.148" ID x 0.25" OD) specifically for No. 6 screw sizes, the washer's split design creates constant spring tension that counters loosening from machinery vibration, thermal cycling, and dynamic loads. The Rockwell C38 hardness provides optimal balance between flexibility and strength, preventing deformation under pressure while maintaining effective locking action. Ideal for industrial equipment assembly, automotive components, and electrical enclosures, this ASME B18.21.1 compliant washer solves common fastening failures in demanding environments where reliability cannot be compromised.
Specification Summary & Compliance
This standard split lock washer features precise dimensional specifications: 0.148" inner diameter, 0.25" outer diameter, and 0.031" thickness. Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance requirements. The washer meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) compliance for chemical safety regulations. The Rockwell C38 hardness rating ensures consistent material properties and reliable performance across industrial applications.
