Import Flat Washer — Buy in Bulk from Supplier in China

Flat washers from Tianjin Yushu T.I.T Co., Ltd are precision-manufactured components designed to distribute load and prevent surface damage in mechanical assemblies. They are produced in accordance with DIN125 and DIN126 standards, with inner diameters ranging from 3mm to 50mm and outer diameters from 6mm to 80mm. Thicknesses vary from 0.5mm to 5mm, depending on size, and are manufactured in carbon steel, stainless steel A2 and A4, and brass. These dimensions align with international mechanical fastening norms and are verified against ISO 7380 for dimensional tolerances.

The materials used are selected for application-specific performance. Carbon steel washers are zinc-plated for basic corrosion resistance, while stainless steel variants offer superior resistance in humid or chemical environments. Brass washers are used in electrical or marine applications where non-sparking and non-magnetic properties are required. Surface treatments follow standard industrial practices; no proprietary coatings are claimed. The washers are cold-formed, not forged, and undergo light deburring to remove sharp edges without altering dimensional tolerances.

These washers are commonly used in automotive suspension systems, construction steel framing, and industrial machinery where consistent torque transmission is critical. Buyers include OEMs in the machinery sector, maintenance contractors, and distributors serving the HVAC and electrical industries. Trade terms include FOB Tianjin Port, with packaging in bulk cartons of 1,000 to 5,000 pieces per box. MOQ and lead time are confirmed upon request, as they vary by size and material.
