Import Conical Washer — Buy in Bulk from Supplier in India

Swarna Fasteners supplies conical washers made from carbon steel and stainless steel grades, with outer diameters ranging from 8 mm to 50 mm and thicknesses from 1.5 mm to 6 mm, as specified in the product data. These washers follow DIN 6797 and ISO 7089 standards for conical spring washer geometry, with a helix angle typically between 15 and 20 degrees to ensure consistent load distribution under vibration.

The washers are manufactured using cold forming processes, with surface finishes including plain, zinc plated, or passivated stainless steel. Zinc plating provides corrosion resistance suitable for indoor or dry environments, while 304 and 316 stainless steel variants are used in wet or marine applications. Typical material hardness ranges from 38 to 45 HRC for carbon steel, and 180 to 220 HV for austenitic stainless steel, aligning with industry norms for spring washer performance.

These washers are commonly purchased by machinery manufacturers, automotive suppliers, and industrial equipment assemblers in Europe and Southeast Asia for use in bolted joints subject to thermal cycling or dynamic loads. Buyers typically order in bulk quantities of 1,000 to 10,000 pieces per size, packaged in polyethylene-lined cartons or bulk bins. Trade terms are usually FOB Delhi or CIF port, with lead times of 15 to 25 days after order confirmation.
