Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›The Hex Flange Nut from Kunshan Alex Railway Fastening Co, .Ltd. is a precision-engineered fastener designed for high-load applications in railway and industrial machinery. It conforms to DIN 6921 standards with metric thread sizes ranging from M6 to M20, and features a hexagonal head with an integrated flange measuring 1.5 times the nominal diameter. The flange width and thickness are optimized to reduce bearing pressure on mating surfaces, preventing surface deformation under torque.
These nuts are manufactured from carbon steel grade 8.8 or stainless steel A2-70, as per material traceability in the supplier's production records. Surface treatment is typically zinc-plated with a yellow chromate finish for corrosion resistance, though plain finish is available on request. The hardness range is 26-34 HRC for carbon steel, and the thread tolerance follows ISO 965-1 Class 6g. These are not generic fasteners but components built to meet mechanical assembly demands in vibration-prone environments.
Primary buyers include manufacturers of rail infrastructure, heavy equipment, and automotive sub-assemblies requiring reliable bolted joints. The product is shipped in bulk polybagged lots of 1,000 to 5,000 pieces per carton, with custom packaging available. Lead time is typically 15 to 25 days after order confirmation. Trade terms include FOB Shanghai, with payment via T/T or L/C. MOQ is not stated in the listing and must be confirmed directly with the supplier.

Before ordering, verify the material grade, thread tolerance, and surface finish with a sample. Request material certificates (EN 10204 3.2) and hardness test results for each batch. Confirm the DIN 6921 compliance through a physical inspection of the nut’s flange profile and thread geometry. Do not rely on supplier claims without documentation.
Lead time is typically 15 to 25 days after order confirmation, but confirm this directly with the supplier. Payment terms are usually T/T or L/C. Incoterms are FOB Shanghai, so ensure the supplier handles export clearance. Packaging must be moisture-resistant, with individual polybagging for small nuts to prevent corrosion during transit.
Perform a random sample inspection for thread engagement, flange flatness, and coating uniformity. Use a thread gauge to check Class 6g tolerance. Conduct a salt spray test on at least three samples if corrosion resistance is critical. Request a commercial invoice with HS code 7318.16 and a packing list matching the carton count. Retain samples for quality reference upon arrival.
