Heavy-Duty HDG Fender Washers for Maximum Load Distribution

HDG fender washers DIN9021 feature oversized outer diameter to disperse pressure and avoid thin metal/timber tearing. Stress-relieved steel prevents warping during galvanizing; centrifugal separation stops washers from sticking together. Inner holes pre-enlarged for smooth bolt assembly, edges tumbled to remove burrs. Zinc coating over 45μm fits solar frames, HVAC ducts and outdoor decking. Moisture-proof cartons & fumigation-free pallets for export, custom OD sizes available.
