Silicon Bronze Lock Washers
Medium Profile Split Ring Lock Washers
- Used to prevent fasteners from loosening unintentionally
- Split and bent to create a spring-like effect
- Add extra pressure to fastener assembly resulting in higher resistance to rotation
- Highly corrosion resistant and durable silicon bronze
- Suitable for marine, corrosive and high heat environments
- Silicon bronze is made of copper, silicon and various other alloys
Split ring lock washers are used to prevent nuts, bolts, and screws from vibrating loose. Lock washers are split at a certain point and bent giving them a helical shape. These lock washers are compressed during installation adding extra pressure to the nut or bolt and material. This extra pressure creates a resistance to rotation. The edges or the split may add extra holding power by digging into the nut. Split ring lock washers are used where constant vibration occurs.
Note: All Silicon Bronze products will develop a patina based on the environment and time. These fasteners are not coated with any sealants to prevent a patina from forming. Depending on when the product was manufactured, you may receive a product that has started to develop a patina.
