Product Description

Product Description
DIN 125 Stainless Steel Flat Washers / ISO 7089 Unchamfered Plain Washers
DIN 125 Form A (ISO 7089) Stainless Steel Flat Washers are essential distribution components designed to increase the bearing surface under a fastener's head. By spreading the clamping force evenly over a wider area, they prevent surface damage to the substrate and counteract settlement in bolted joints. Manufactured from premium austenitic stainless steel, these washers offer exceptional corrosion resistance, making them ideal for outdoor, marine, and sanitary industrial applications.
Specifications & Size Range
Standard Compatibility: Fully compliant with DIN 125 Form A (unchamfered) and ISO 7089 international specifications.
Size Range: M1.6 – M64 (Common stock sizes: M3, M4, M5, M6, M8, M10, M12, M14, M16, M20, M24, M30).
Thickness Tolerances: Manufactured with precision thickness controls according to standard metric parameters.
Premium Stainless Steel Grades
A2-70 / A2-80 (Stainless Steel 304 / 301):
Characteristics: Offers excellent resistance to atmospheric corrosion, organic chemicals, and food products.
Best For: General outdoor construction, commercial food processing equipment, kitchenware, and household appliances.
A4-70 / A4-80 (Stainless Steel 316 / 316L):
Characteristics: Alloyed with Molybdenum to provide elite resistance against pitting and crevice corrosion in chloride or acidic environments.
Best For: Marine engineering, coastal infrastructure, chemical processing plants, medical devices, and wastewater treatment facilities.
Surface Finish & Appearance
Bright Polished: Clean, non-coated, and naturally bright metallic surface. Completely free of oil or chemical residues, ensuring compatibility with sanitary and high-cleanliness environments.
Industrial Applications
Marine & Coastal Engineering: Paired with A4 stainless steel bolts/nuts to secure dock structures, boat hulls, rigging, and coastal solar arrays.
Food & Pharmaceutical Processing : Utilized in sanitary piping systems, mixing tanks, and bottling machinery where regular chemical washdowns are mandatory.
Outdoor Infrastructure & Solar PV: Protecting soft aluminum rail surfaces or steel brackets from cracking under tight clamping force in commercial solar fields.
Piping & Petrochemical Industries: Serving as a critical buffer between heavy flange bolt heads and soft gasket surfaces to maintain uniform seal pressure.
