We are a trusted manufacturer and supplier of high-quality washers, committed to delivering reliable fastening solutions worldwide. With advanced production technology and stringent quality control, our washers are designed to meet the diverse needs of industries including automotive, construction, manufacturing, and aerospace. Our customer-focused approach ensures timely delivery and customization options, making us a preferred partner for both large-scale projects and specialized applications.
Our washers are manufactured using premium materials such as carbon steel, stainless steel (grades 304, 316), alloy steel, duplex and super duplex stainless steels, high nickel alloys, and titanium. Available in various types including flat washers, spring washers, lock washers, and flange washers, they conform to key international standards like ASTM F436, ASTM F844, ISO 7089, and DIN 125. The washers undergo rigorous testing for dimensional accuracy, hardness, tensile strength, and corrosion resistance to ensure optimum performance under different operating conditions.
The production of our washers involves precision stamping or machining from high-grade metal sheets, followed by heat treatment to enhance strength and durability. Surface finishing options such as zinc plating, galvanization, and passivation provide excellent resistance against corrosion and wear. Our washers meet stringent quality requirements per ASTM, ISO, and DIN standards, ensuring consistent compatibility and reliability with bolts, nuts, and other fasteners.
Washers play a critical role in distributing load, reducing vibration, preventing leakage, and protecting surfaces in assembly operations. Our washers are widely used in automotive engines, heavy machinery, construction equipment, marine vessels, and aerospace components. Depending on the type and material, they help improve joint stability, extend the lifespan of assemblies, and enhance overall safety in demanding industrial environments.
