Professional Applications & Engineering Value

This 316 stainless steel split lock washer delivers exceptional engineering value in corrosive and high-vibration environments where fastener security is critical. The split lock design creates continuous spring tension that compensates for thermal expansion, vibration, and load variations, preventing costly downtime from loose connections. Manufactured to ASME B18.21.1 standards with precise 0.45" ID and 0.776" OD dimensions, these washers provide perfect compatibility with 7/16" screws in machinery, marine equipment, chemical processing systems, and offshore installations. The Rockwell C35 hardness ensures the washer maintains its spring properties under continuous load, while the 316 stainless steel material offers superior resistance to chlorides, acids, and extreme temperatures that would compromise ordinary fasteners.
