Flat washers
Flat washers from China Union Metal Products Co., Ltd are precision-machined components designed to distribute load and reduce friction in bolted assemblies. Available in standard metric sizes from M3 to M24, with outer diameters ranging from 6mm to 40mm and thicknesses from 0.5mm to 4mm, these washers are manufactured to meet DIN 125 and ISO 709 standards. The material options include carbon steel, stainless steel 304, and stainless steel 316, each selected for mechanical performance and environmental resistance.
Carbon steel washers are typically zinc-plated for basic corrosion protection, while stainless variants offer superior resistance in humid or chemical environments. The surface finish is smooth and free of burrs, with tolerances held within ±0.05mm on diameter and ±0.02mm on thickness, consistent with industrial norms for general mechanical use. These washers are not heat-treated and are intended for non-structural applications where load spreading is critical, not high-tension clamping.
They are commonly used in automotive suspension systems, construction fastening, and industrial machinery where vibration resistance and surface protection are required. Buyers in the machinery, automotive, and light construction sectors source these washers in bulk for assembly lines. Trade terms include FOB Shanghai or CIF destination, with packaging in polybags or cartons of 1000 to 5000 pieces depending on size. Minimum order quantities are flexible and confirmed per request.

China Union Metal Products Co., Ltd operates from Jiaxing, Zhejiang, a region known for precision hardware manufacturing. The company is verified as a harbor-tier supplier with no public data on years in business, workforce size, or annual turnover. Their listing shows no certifications, client testimonials, or production capacity figures. The focus of their offering is on standard flat and spring washers, with no indication of custom tooling or in-house testing equipment.
They do not claim ISO certification, SGS compliance, or export history beyond the platform listing. Response rate and average reply time are not tracked, suggesting limited sales team engagement. Buyers should treat this as a manufacturer of standard components rather than a technical partner. No mention is made of quality control processes, material traceability, or third-party inspection services.

Sourcing Flat washers from China Union Metal Products Co., Ltd - China Import Guide
Before placing an order, verify the material grade by requesting a mill test report for stainless steel washers, especially if the application involves corrosion exposure. Confirm that the zinc plating on carbon steel is RoHS-compliant if destined for EU markets. Ensure the dimensions match your bolt sizes exactly, as mismatched inner diameters can cause assembly failure. Do not assume certifications like ISO are held unless documented evidence is provided.
Confirm Incoterms with the supplier - FOB Shanghai is typical, but CIF may be available. Lead time is not stated; expect 15 to 30 days after order confirmation, depending on volume and material availability. Payment terms are not listed, so clarify whether advance payment, LC, or T/T is accepted. Packaging must be moisture-resistant for stainless steel to prevent surface staining during ocean transit.
Perform incoming quality checks on random samples: measure at least 10 washers per batch for inner and outer diameter, thickness, and surface burrs. Use a magnet to test for magnetic response in stainless steel - 304 should be weakly magnetic at most. Request a batch label showing material, size, and production date. If used in safety-critical assemblies, insist on a traceability record linking each batch to its material certification.
