Import Bolt — Buy in Bulk from Supplier in China

Haitian Fastener Industry Co., Ltd manufactures bolts from their base in Ningbo's Tiangu Industrial Estate, drawing on a material palette that spans mild steel grades 1010 through 1025, medium carbon steels 1030 and 1035, high carbon steels 1040 through 1055, stainless grades 202, 302, and 304, plus alloy steel and brass. The stated diameter range covers M4 to M48, with lengths from 10 mm to 480 mm, positioning this supplier across a broad spectrum from precision light engineering through heavy structural applications. Surface finishes include chrome plating, zinc plating, nickel plating, silver plating, and gold plating, with production to customer drawings or samples and standards including DIN, ANSI, JIS, BS, and ISO.

The material specification granularity is notably detailed: mild steels (1010, 1015, 1020, 1025) suit general purpose fastening with lower strength requirements and good formability; medium carbon grades (1030, 1035) offer increased strength for machinery and automotive; high carbon grades (1040, 1045, 1050, 1055) deliver elevated hardness and wear resistance for demanding applications. Stainless options (202, 302, 304) provide corrosion resistance, with 304 offering superior performance in marine or chemical environments. The supplier also produces associated fasteners including nuts, washers, rivets, and pins, enabling single-source procurement for assembled products.

Buyers span OEM manufacturers, construction contractors, automotive suppliers, and maintenance operations requiring standard or customised fastening solutions. Payment terms are listed as T/T or L/C at sight, with seaworthy packing or customer-specified alternatives. The Ningbo location offers port access for containerised export. Buyers should confirm minimum order quantities, production lead times for non-standard items, and whether the supplier holds ISO 9001 or IATF 16949 certification given the automotive material grades offered.

Haitian Fastener Industry Co., Ltd is located in Tiangu Industrial Estate, Nine-Dragon Lake Town, Ningbo, Zhejiang Province, China, postal code 315040. Ningbo ranks among China's principal fastener export hubs, with established supply chains for steel rod, surface treatment facilities, and container port infrastructure. The supplier carries imported tier and harbor trust tier designations, with zero percent response rate and no average response hours recorded. This profile suggests a manufacturing entity with export orientation but limited demonstrated engagement responsiveness through the platform channel.

The company produces a comprehensive fastener range beyond bolts alone, including nuts, washers, rivets, pins, and non-standard special fasteners. No founding year, employee count, annual turnover, factory area, or specific quality system certifications are stated in the source data. The ability to work from customer drawings indicates in-house engineering or tooling capability. Buyers should verify current ISO 9001 registration status, request factory audit reports, and confirm whether IATF 16949 automotive quality certification applies given the automotive-grade carbon steels in the material list. The supplier's willingness to produce non-standard items is a potential differentiator, though custom tooling costs and minimum volumes require direct negotiation.
