Stainless Steel Flat Washer
Product introduction
Flat washers, indispensable disc-shaped fasteners, are inserted between bolts, nuts, or screws and connected materials. Our diverse product range features premium materials like stainless steel (304/316), galvanized carbon steel, brass, nylon, and rubber. Stainless steel washers shine in marine and chemical applications with exceptional corrosion resistance; carbon steel variants, treated with zinc or Dacromet, offer a cost-effective solution for general use. Nylon and rubber options provide insulation, vibration dampening, and non-marring surface protection. These washers maximize contact area to evenly distribute pressure, preventing substrate damage, while serrated metal types enhance anti-loosening performance, and rubber/nylon ones create seals and protect against scratches.
With inner diameters spanning M2 to M30, outer diameters from 4mm to 48mm, and thicknesses ranging 0.5mm to 6mm, our washers suit light to heavy loads. Rigorously compliant with international standards including GB/T 95/97, ISO 7089/7090, they ensure seamless compatibility across global projects. Applied in industries from heavy machinery and automotive to electronics and DIY, our flat washers undergo strict testing for hardness, strength, and corrosion resistance. Customization options for size, material, and surface treatment are available, offering reliable fastening solutions tailored to diverse needs.
