Bolts and nuts from Jilin Senfeng Pipe Co., Ltd. are produced in carbon steel, stainless steel 304 and 316, and alloy steels such as 4140, with thread sizes from M3 to M48 and lengths up to 300mm. The products are manufactured to meet ASTM A307, ASTM A449, and ISO 898-1 standards. Surface treatments include zinc plating, Dacromet, and hot-dip galvanizing, with coating thicknesses varying by application requirement.
Stainless steel variants use AISI 304 or 316 with a minimum 18% chromium and 8% nickel content. Carbon steel bolts are heat-treated to achieve property classes 4.8, 8.8, or 10.9, with hardness levels of 140-220 HV, 240-340 HV, and 320-400 HV respectively. Tensile strength ranges from 400MPa for Class 4.8 to over 1000MPa for Class 10.9. These are not decorative fasteners but engineered for mechanical and structural use.
Customers in pipeline construction, heavy machinery, and rail infrastructure across Central Asia and the Middle East source these items for high-load applications. Packaging is in 25kg polypropylene bags inside cartons, stacked on wooden pallets. Trade terms include FOB Dalian Port and CIF to major ports. MOQ is typically 1 metric ton per size and grade. Confirm exact material grade, coating type, and test reports before ordering.

Verify the exact material grade (e.g., 304 vs 316 stainless, Class 8.8 vs 10.9 carbon steel) and surface treatment (zinc, Dacromet, galvanized) before ordering. Request a mill test certificate for chemical composition and mechanical properties. Do not accept generic claims of 'quality' or 'standard-compliant' without documented test results tied to the batch.
Confirm Incoterms: FOB Dalian Port is referenced, but clarify whether port charges, documentation, and export customs clearance are included. Lead time is not stated but typically ranges from 20 to 45 days. Payment terms are not listed; assume 30% advance and 70% against BL copy unless otherwise agreed. Always request a commercial invoice with HS code and packing details for customs.
Conduct incoming inspection using a thread gauge, caliper for head dimensions, and a hardness tester for critical grades. Check for coating uniformity and signs of blistering or peeling. Retain samples for third-party lab testing if used in safety-critical systems. Ensure the supplier provides a Certificate of Conformity with batch numbers, and retain all documentation for customs and liability purposes.
