Description
The 316 Stainless Steel GB93 Split Lock Washer is a high-performance, helical spring washer designed to provide a positive locking action in bolted assemblies. Conforming to the Chinese National Standard (GB93), this fastener is specifically engineered to resist the loosening of nuts and bolts caused by vibration, dynamic loads, and thermal expansion. Manufactured from premium 316 Stainless Steel, this Split Lock Washer offers a substantial upgrade in corrosion resistance and oxidation resistance over standard steel or 304-grade stainless steel. This makes it the ideal choice for demanding environments, particularly those involving saltwater, chemicals, or high moisture.
Features & Benefits
- Material: High-quality 316 stainless steel for excellent corrosion and oxidation resistance.
- Locking Function: Split-ring design creates spring tension to prevent loosening under vibration.
- Durability: Resistant to wear, deformation, and rust in humid or harsh environments.
- Finish: Smooth, uniform surface with high concentricity and dimensional accuracy.
