Heavy-Duty HDG Square Beveled Washers for Structural Beams (DIN 434 / 435)
HDG square bevel washers follow DIN434 (8% slope for channels) and DIN435 (14% slope for I-beams). Square edges lock against beam webs to prevent spinning during torque tightening. Pre-tumbled to remove burrs for smooth HDG coating without sharp zinc spikes. Inner holes pre-enlarged for easy assembly with structural bolts. 50–85μm zinc layer resists outdoor corrosion for steel workshops, crane girders and highway bridges, packed moisture-proof on pallets for sea export.
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.
