651 Silicon Bronze Split Lock Washer
Our 651 Silicon Bronze Split Lock Washers are corrosion‑resistant locking components designed to help prevent fastener loosening caused by vibration, shock, and thermal cycling. Manufactured from silicon bronze alloy C65100, these lock washers combine good spring characteristics with excellent resistance to corrosion, making them well suited for demanding service environments.
The split (helical) lock washer design creates spring tension when compressed under a nut or bolt head, helping maintain preload and resist rotation in the joint. Silicon bronze offers improved mechanical strength compared to traditional brass while remaining non‑magnetic and highly resistant to saltwater, moisture, and many corrosive agents.
Engineered for durability and reliable locking performance, 651 Silicon Bronze Split Lock Washers are commonly used in marine hardware, shipbuilding, electrical grounding, architectural installations, outdoor structures, and industrial assemblies exposed to aggressive environments. The alloy’s inherent corrosion resistance eliminates the need for protective coatings, while the split washer profile helps maintain clamp load over time. Available in a wide range of sizes, these lock washers provide a dependable fastening solution for OEM manufacturing, maintenance, and repair operations where corrosion resistance, conductivity, and vibration control are critical.
