Professional Applications & Engineering Value

This 316 stainless steel split lock washer delivers exceptional engineering value in demanding industrial environments where vibration-induced fastener failure poses significant operational risks. The split lock washer design creates continuous spring tension that compensates for thermal expansion, material relaxation, and dynamic loads, maintaining clamp force where standard flat washers fail. Manufactured from marine-grade 316 stainless steel, it provides superior resistance to chlorides, chemicals, and extreme temperatures, making it ideal for marine equipment, chemical processing plants, food processing machinery, and offshore applications. The standard split lock configuration ensures easy installation and reliable performance across thousands of cycles, while the Rockwell C35 hardness balances spring properties with durability to prevent cracking under repeated deflection.
