Professional Applications & Engineering Value

These 316 stainless steel split lock washers deliver critical engineering solutions where vibration loosening and corrosion pose significant challenges. The split lock washer design creates continuous spring tension that counters rotational forces, preventing fastener failure in machinery, equipment, and structural applications. The marine-grade 316 stainless steel composition offers exceptional resistance to chlorides, chemicals, and extreme environments, making these washers ideal for marine equipment, chemical processing plants, and outdoor infrastructure. With precise dimensions for 5/16" screw applications, these washers ensure proper fit and function while the Rockwell C35 hardness maintains spring properties through repeated loading cycles. The combination of vibration-resistant performance and corrosion protection extends equipment service life while reducing maintenance frequency and downtime in industrial operations.
