137505 - Silicon Bronze Washer Split Spring- 1/2"

Spring split washers function as dynamic locking devices, employing an offset helical twist that generates continuous spring tension between the fastener and substrate. This mechanical preload actively resists vibration-induced loosening, making them ideal for applications subject to cyclic stress, thermal cycling, or persistent vibration.

Manufactured from silicon bronze, it provides outstanding resistance to seawater corrosion, atmospheric oxidation, and chemical exposure throughout its operational lifespan without requiring protective coatings or maintenance interventions — critical for marine installations, offshore equipment, and coastal infrastructure.
