Professional Applications & Engineering Value
This 18-8 stainless steel split lock washer addresses critical vibration-related failures in industrial assemblies. The split lock washer design creates continuous spring tension that compensates for thermal expansion, material settling, and dynamic loads. Engineered specifically for No. 5 screw applications, the precise 0.133" internal diameter ensures optimal grip without damaging fastener threads. The Rockwell C35 hardness provides the ideal balance between flexibility and strength, maintaining locking force through countless vibration cycles. Ideal for machinery, electrical enclosures, and automotive components where vibration resistance is paramount, this washer prevents costly downtime and maintenance in demanding environments.
