Professional Applications & Engineering Value

This 18-8 stainless steel split lock washer addresses critical vibration-induced loosening challenges in industrial fastening systems. The split lock washer type creates continuous spring tension against both the bearing surface and fastener head, maintaining clamp load where conventional flat washers fail. Engineered with Rockwell C35 hardness, it provides optimal elastic recovery while resisting permanent set deformation. The corrosion-resistant properties of 18-8 stainless steel make it ideal for harsh environments including chemical processing, marine applications, and outdoor equipment. With precise 0.174" ID dimensions specifically designed for No. 8 screw size applications, this washer eliminates compatibility issues in assembly lines and maintenance operations across machinery, electrical enclosures, and structural frameworks.

Specification Summary & Compliance

This split lock washer features dimensional specifications of 0.174" inner diameter, 0.267" outer diameter, and 0.047" thickness, engineered for No. 8 screw applications. Manufactured to ASME B18.21.1 standards for consistent performance and interchangeability. The product maintains full compliance with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements (updated 06/14/2023, 235 SVHC), ensuring environmental safety and regulatory acceptance for global industrial markets.
