Washer AF03000036 | High-Strength Alloy Steel Washer for Hydraulic Rock Drills

High-Strength Disc-Lock Washer for Hydraulic Rock Drills
Engineered for extreme underground mining environments, this disc-lock washer ensures reliable fastening in high-pressure hydraulic systems. Constructed from 1045 alloy steel with a zinc-plated surface (48-hour salt spray test compliance), it withstands continuous dynamic loads while resisting corrosion in harsh conditions.

Technical Specifications & Design
The washer adheres to ISO 7090 standards for heavy series washers, with a disc-spring geometry that provides 3 mm thickness for optimal load distribution. Its M20 nominal size (20.83 mm ID × 36 mm OD) ensures compatibility with standard hydraulic cylinder bolts. The concave-convex design creates a mechanical wedge effect, preventing loosening under vibration without requiring additional torque tools.
