The Fish Bolt and Fishplate Bolt from Kunshan Alex Railway Fastening Co, .Ltd. are forged steel fasteners designed for securing rail joints in railway track systems. These bolts conform to DIN 650 standard dimensions, with common diameters of 24mm and lengths ranging from 165mm to 220mm, depending on rail profile and track class. The product is manufactured to withstand dynamic shear forces and thermal expansion in heavy-haul and high-speed rail environments.
The bolts are made from medium-carbon alloy steel, typically grade 10.9 or 12.9 per ISO 898-1, with a hot-dip galvanized finish for corrosion resistance. Surface hardness ranges from 32 to 39 HRC, ensuring resistance to thread stripping under repeated loading. These specifications align with standard railway fastening requirements in Europe and Asia, where DIN and EN standards govern track integrity. The manufacturing process includes precision threading and torque-controlled heat treatment to maintain structural consistency.
These components are primarily sourced by railway infrastructure contractors, track maintenance agencies, and rolling stock manufacturers in Southeast Asia, the Middle East, and Eastern Europe. Buyers typically order in batches of 5,000 to 50,000 units per shipment. Packaging is in bulk steel crates or wooden pallets, with individual bolts wrapped in anti-rust paper. Trade terms are commonly FOB Shanghai or CIF destination port, with lead times of 30 to 45 days after order confirmation.

Before placing an order, verify the material grade and hardness certification for each batch. Request mill test reports for tensile strength and Rockwell hardness per ISO 898-1 and ASTM E18. Confirm that the galvanizing thickness meets DIN 50969 requirements with a coating gauge. Do not accept bolts without documented mechanical test results, especially for heavy-haul or high-speed rail projects.
Confirm the Incoterms, as FOB Shanghai is standard, but CIF terms require clarification on insurance coverage. Lead time is typically 30 to 45 days after deposit, but production scheduling depends on order volume. Payment terms are usually 30% advance, 70% against copy of BL. Ask for a production timeline and inspection window before shipment to avoid delays.
Perform a pre-shipment inspection focusing on surface finish, thread integrity, and packaging. Use a thread gauge to check pitch and diameter tolerance. Inspect for zinc flaking or bare spots under magnification. Request a packing list with batch numbers matched to test reports. Ensure the supplier provides a signed quality declaration and export documentation compliant with your country’s rail safety regulations.
