Stainless 18 8 Hi Collar Lock Washer (Inch)
Our Stainless Steel 18‑8 High Collar Lock Washers are corrosion‑resistant locking components designed to provide enhanced vibration resistance and secure fastener retention in demanding applications. Manufactured from 18‑8 stainless steel (Type 304 equivalent), these lock washers offer excellent resistance to rust, oxidation, moisture, and general environmental exposure.
The high collar (high‑crown) lock washer design features a double‑coiled profile with increased spring height compared to standard split lock washers. This design delivers greater spring tension, allowing the washer to maintain clamp load more effectively under vibration, shock, and thermal cycling. Stainless construction ensures long service life while maintaining compatibility with stainless bolts and nuts
Engineered for strength and reliability, 18‑8 Stainless High Collar Lock Washers are commonly used in machinery, equipment assemblies, electrical installations, marine hardware, enclosures, and general industrial fastening applications where added locking performance is required. The increased collar height improves resistance to flattening and loss of preload, making these washers well suited for applications subject to movement or repeated load changes. Available in a wide range of sizes, these lock washers provide a dependable fastening solution for OEM manufacturing, maintenance, and repair operations requiring corrosion resistance and enhanced vibration control.
