Import Bolts — Buy in Bulk from Supplier in China

Zhejiang Anda Fasteners Co., Ltd. manufactures hexagon head bolts from carbon steel in dimensions from M3 to M24, conforming to GB, ISO, ANSI, DIN, BSW, and JIS standards. The supplier operates from Daqiao New Area of Haiyan Economic Development Zone in Jiaxing, Zhejiang Province. Their product positioning centres on heavy-load and harsh-environment applications across construction, automotive, and machinery sectors. The stated tensile strength and robust design suggest heat-treated alloy or medium-carbon steel grades, though exact material specifications require direct confirmation.

Carbon steel hex bolts in the M3 to M24 range typically span property classes 4.8 through 12.9, with Anda likely focusing on the mid-to-high range given their emphasis on demanding applications. Head dimensions follow ISO 4014 or DIN 931 for partial thread and ISO 4017 or DIN 933 for full thread variants. Thread tolerances are typically 6g for standard fits. Surface treatments may include plain oil, zinc plating, or hot-dip galvanising, though the source only confirms carbon steel as the base material. The multi-standard approach (GB, ISO, ANSI, DIN, BSW, JIS) indicates export-oriented production with thread form and pitch adaptations for different markets.

Primary buyers include construction contractors for structural steel connections, automotive tier suppliers for chassis and powertrain assemblies, and machinery builders for frame and bearing mountings. The M16 to M24 sizes suit heavy structural work, while M3 to M8 serve precision machinery and automotive interior panels. Import buyers should verify Anda's actual stock versus made-to-order lead times, confirm whether certificates from SGS or ISO accreditation bodies are current and scope-appropriate, and establish packaging specifications to prevent thread damage during ocean transit from Chinese ports.

Zhejiang Anda Fasteners Co., Ltd. is situated in Daqiao New Area of Haiyan Economic Development Zone, Jiaxing, Zhejiang 31405, China. The company holds an imported supplier tier and harbor trust designation. Like its counterpart, Anda shows a zero percent response rate with zero average response hours on platform metrics, indicating that direct communication channels may prove more reliable than mediated enquiry systems. The location in Jiaxing places it within China's dense Yangtze River Delta manufacturing cluster with access to Shanghai and Ningbo ports.

The source references ISO and SGS quality certifications, though buyers should verify certificate numbers, scope of accreditation, and validity dates directly with Anda. No specific year of establishment, factory floor area, employee count, or annual turnover figures appear in the provided profile. The company emphasises export quality and direct manufacturer connection, positioning itself as a wholesale source rather than a trading intermediary. Prospective partners should request factory audit reports, production capability statements, and client reference projects before finalising supply agreements.
