Import Bolts — Buy in Bulk from Supplier in China

He Bei Fastener Technology Co., Ltd. supplies hexagon head bolts manufactured to DIN933 standards, with diameters from M6 to M8 and lengths spanning 20 mm to 400 mm. The source surface treatments include zinc plated (z.P), black oxide, hot dip galvanised, and dacromet, each selected to match specific environmental exposure requirements. These are full-thread bolts where the thread runs the entire shank length, a defining characteristic of the DIN933 classification that distinguishes them from partial-thread alternatives.

Material options stated in the source ensure structural integrity and wear resistance, though the specific grade is not named, typical Chinese fastener production for this specification uses carbon steels such as Q235 or 35# steel, with alloy upgrades for higher tensile demands. Surface treatments serve distinct purposes: zinc plating offers sacrificial corrosion protection at economy cost, hot dip galvanising provides thicker coating layers for outdoor and marine exposure, black oxide suits dry interior environments where lubricity matters, and dacromet delivers chromium-free corrosion resistance with low hydrogen embrittlement risk. DIN933 compliance ensures thread pitch, head height, across-flat dimensions, and mechanical properties conform to the German standard, interchangeable with ISO 4017 in most applications.

These bolts serve construction frameworks, automotive assembly lines, and general machinery manufacturing where through-hole fastening with full thread engagement is required. Buyers include structural steel fabricators, OEM equipment manufacturers, and maintenance procurement divisions. Trade terms mentioned include FOB and CIF, though exact port and pricing require direct confirmation. The supplier lists flexible MOQ, but no minimum quantity is specified in the data, so buyers should clarify this before committing.

He Bei Fastener Technology Co., Ltd. is located at No 88, Economic And Technical Development Zone, Handan 056000, China, placing it within Hebei Province, a region with deep concentration in fastener manufacturing. The supplier tier is marked as imported and trust tier as harbor, with a response rate of 0.00 percent and average response hours at zero, indicating no response activity is recorded in the data. The address situates the company in an established industrial zone, which typically offers infrastructure for metalworking and heat treatment, though the listing does not confirm in-house versus outsourced processing.

The source description references ISO and SGS certifications, but the listing provides no certificate numbers, scope, or validity dates that can be verified. No employee count, annual revenue, year of establishment, or client references appear in the data. Buyers should treat uncorroborated certification claims as unverified and request current copies of quality system and product test certificates directly from the supplier before placing orders.
