Import Flat Washers — Buy in wholesale FOB from Supplier in China

Flat washers from Shanghai Fangyuan Fasteners Co., Ltd. are manufactured in low carbon steel, #45 steel with heat treatment, spring steel, stainless steel, and brass, conforming to ASME/ANSI, DIN, ISO, JIS, and BS standards. Available sizes include CL4, CL6, CL8, CL10, CL12, SAE J995 Grade 2, 5, and 8, as well as A194 2H and ASTM A563 Grade A. These washers are designed to distribute clamping load evenly and prevent surface damage in bolted assemblies, commonly used in fencing, deck construction, and light industrial machinery.

The washers are offered in multiple finishes: plain, black oxide, clear zinc, yellow zinc, blue zinc, and hot-dip galvanized. Material composition follows standard industry tolerances for hardness and tensile strength, with low carbon steel typically meeting ASTM A36 or equivalent. Brass washers are typically C26000 alloy, while stainless steel variants are typically 304 or 316 grade. Surface treatments are applied for corrosion resistance, not cosmetic appeal, and are selected based on environmental exposure requirements.

These washers are sourced by distributors, OEMs in agricultural equipment, and contractors in construction who require reliable load distribution without thread damage. Orders are fulfilled in bulk cartons on wooden pallets, with custom packaging available. Lead time is typically 30 to 40 days depending on order volume. Trade terms include FOB Shanghai, CIF, CFR, EXW, DDP, and DDU. Payment methods accepted are T/T, L/C, and Western Union. No minimum order quantity is stated; buyers should confirm directly.
