Professional Applications & Engineering Value

This 316 stainless steel split lock washer delivers critical engineering solutions for applications where vibration resistance and corrosion protection are paramount. The split lock design creates continuous spring tension that counters loosening in high-vibration environments such as industrial machinery, marine equipment, and chemical processing systems. Made from 316 stainless steel, this washer provides superior resistance to chlorides and acidic conditions compared to standard stainless grades. The precise 1.28" ID ensures perfect fitment for 1 1/4" screw applications, while the Rockwell C35 hardness maintains structural integrity under repeated loading cycles. Engineers specify this ASME B18.21.1 compliant washer for critical assemblies where failure is not an option, providing reliable performance in the most demanding industrial settings.

Specification Summary & Compliance

This split lock washer features precise dimensional specifications including 1.28" inner diameter, 1.79" outer diameter, and 0.313" thickness. Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance requirements. The washer demonstrates full compliance with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, including the latest SVHC updates. The Rockwell C35 hardness ensures consistent mechanical properties and reliable spring performance across all production batches, meeting the stringent requirements of industrial and marine applications.
