The ANSI/ASME B18.21.1 Standard Spring Washers from Zhejiang Zhongrui Auto Parts Co., Ltd. are designed to provide axial load and vibration resistance in bolted joints. Made from steel, these washers conform to ANSI/ASME B18.21.1 and are equivalent to GB/T and DIN EN ISO standards, ensuring compatibility with a broad selection of fasteners. The split, helical design allows the washer to compress and generate a spring force, maintaining tension on the bolt over time.
These washers are typically manufactured from high-carbon steel or stainless steel, with a standard thickness ranging from 0.5 mm to 3.0 mm, depending on the bolt size. The outer diameter is standardised to fit common bolt heads, while the inner diameter matches the bolt shank. The material’s typical hardness is 40-50 HRC, providing resilience against deformation under load. Surface finishes include plain, zinc-plated, or phosphate coatings for corrosion resistance.
Common applications include automotive chassis components, industrial machinery, and construction equipment, where vibration or dynamic loads could loosen fasteners. Buyers in these sectors source spring washers to enhance the reliability of bolted connections. The supplier offers bulk packaging in plastic bags or cartons, with each unit marked for identification. Confirm MOQ, lead time, and incoterms directly with Zhejiang Zhongrui Auto Parts Co., Ltd.

Before ordering, confirm the material grade and heat treatment process to ensure the washers meet your application’s load and environmental requirements. Request a material test report (MTR) and verify that the washers conform to ANSI/ASME B18.21.1, GB/T, or DIN EN ISO standards. Check for additional certifications, such as ISO 9001, if required for your industry.
Clarify the incoterms, such as FOB or CIF, and the preferred port of shipment in China. Discuss lead times, which may vary based on order volume and production capacity. Agree on payment terms, such as L/C or T/T, and request samples for physical inspection to verify dimensions, material, and finish before placing a bulk order.
Upon receipt, inspect the washers for correct dimensions, hardness, and surface finish. Use calipers to measure the outer and inner diameters, and a hardness tester to verify the material’s resilience. For critical applications, conduct a load test to ensure the washers can withstand the required spring force. Retain all packaging and documentation for traceability and quality assurance.
