Import Bolts And Nuts, Threaded Rods — Buy in wholesale FOB from Supplier in China

Jilin Senfeng Pipe Co., Ltd. supplies carbon steel and stainless steel fasteners engineered for ductile iron pipe fittings and joints, including hex bolts in full thread DIN933 and partial thread DIN931 patterns, T-head bolts, and threaded rods to DIN975. The carbon steel line covers property classes 4.8, 6.8, and 8.8, while stainless steel options include SS304 and SS316 in A4-70 and A4-80 strength grades. These fasteners secure glands, gaskets, and mechanical joints in pressurised piping systems where leakage resistance and structural integrity are critical.

Carbon steel bolts in grades 4.8, 6.8, and 8.8 offer a graduated strength-to-cost profile: 4.8 suits general assembly with 400 MPa tensile and 0.8 yield ratio, 6.8 suits moderate load, and 8.8 provides 800 MPa tensile for demanding applications. Stainless steel SS304 delivers excellent general corrosion resistance, while SS316 with molybdenum addition resists chlorides and aggressive environments; A4-70 and A4-80 denote respective 700 MPa and 800 MPa tensile strengths in the austenitic stainless range. Threaded rods to DIN975 provide continuous threading for custom-length applications, adjustable coupling, and tensioning in pipeline construction.

These fasteners serve water supply networks, sewage infrastructure, industrial process piping, and construction projects where ductile iron is the primary pipe material. Buyers include municipal engineering contractors, water utility procurement departments, pipe system integrators, and distributor traders serving infrastructure markets. The supplier also lists gaskets as part of their jointing portfolio, suggesting capability to bundle sealing components with mechanical fasteners for complete joint assemblies.

Jilin Senfeng Pipe Co., Ltd. is located at B-1, Jiancaijiayuan, Fukang Road, Panshi, Jilin Province, 132300, China. The company holds a Harbor trust tier on the platform, indicating a baseline verification level, though its response rate registers at 0.00% with zero recorded average response hours. This profile suggests limited or no active engagement through platform messaging channels, and buyers should expect direct outreach rather than rapid platform-based communication.

The supplier's stated specialisation centres on fasteners and jointing components for ductile iron piping: glands, bolts, nuts, gaskets, and threaded rods. Their product description explicitly ties these fasteners to pipe fitting and joint applications rather than general construction, indicating a focused market position. No manufacturing scale, year of establishment, employee count, or revenue figures are provided in the source data, and these should not be assumed. The concurrent listing of gaskets alongside mechanical fasteners suggests assembly bundling capability, though buyers should verify actual stock, production capacity, and quality management system status directly with the company.
