Washer
Washers are used with bolts, screws, and nuts to distribute load, reduce surface damage, and improve fastening stability. They are widely used in machinery, steel structures, construction projects, automotive applications, and industrial assembly.
Hot Dip Galvanized Flat Washers Supplier for Outdoor Fastening
Hot dip galvanized flat washers for bolts, nuts, anchor bolts, threaded rods, steel structures, solar mounting systems, guardrails and outdoor construction projects. Custom sizes, standards and export packaging available.
Heavy-Duty HDG Timber & Dock Washers for Marine Construction
HDG dock washers are thick steel plates with large bearing area to avoid timber crushing for marine docks and wooden bridges. Zinc coating above 50μm resists long-term saltwater corrosion. Edges fully deburred for safe operation; inner holes pre-enlarged to fit HDG bolts smoothly. Available in round/square shapes with thickness 4–10mm, matched with carriage bolts and tie rods. Moisture-proof carton & pallet export packaging, custom offset-hole sizes supported.
Heavy-Duty HDG Square Washers for Slotted Channels and Timber Framing
HDG square plate washers comply with DIN436, featuring large flat bearing surface to bridge slotted solar strut holes and avoid timber crushing. Inner holes pre-enlarged for smooth HDG bolt penetration; edges tumbled to remove burrs without sharp zinc spikes. Thickness ranges 3–10mm, widely used for solar racks, timber frames and anchor bolt bases. Moisture-proof cartons & fumigation-free pallets for sea transport, custom rectangular/offset-hole washers available.
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.
High-Strength HDG Spring Lock Washers (DIN 127B) – Engineered to Prevent Embrittlement
HDG split spring lock washers DIN127B are made of 65Mn spring steel. Strict short-time hot-dip galvanizing avoids annealing loss of elasticity, followed by 200°C baking for 4 hours to eliminate hydrogen embrittlement and prevent cracking. Centrifugal separation prevents interlocking and keeps split gaps unblocked. Zinc coating ≥45μm anti-corrosion for highway guardrails, solar trackers and vibrating pump flanges. Moisture-proof cartons & fumigation-free pallets for bulk export.
DIN126 Hot Dip Galvanized Class C Enlarged Inner Hole Flat Washers
DIN126 Class C hot dip galvanized steel flat washers with enlarged inner hole options, including Type A and Type B dimensions, for construction, steel structures, machinery, and industrial fastening.
