Import Din261 Din186 T Head Bolts — Buy in Bulk from Supplier in China

The DIN261/DIN186 T‑head bolts supplied by Handan Daoning Fasteners Co., Ltd. conform to ASME B18.5, DIN261 and DIN186 standards and are offered in sizes from 1/4" to 1" (M6‑M30). They are produced from carbon steel, alloy steel or stainless steel and are available in SAE J429 grades GR.2, GR.5, GR.8 as well as mechanical classes 4.8, 8.8 and 10.9. Metric (M), UNC and UNF thread profiles are stocked, and finishes include plain, zinc‑plated (clear, blue, yellow or black), black oxide, nickel, chrome and hot‑dip galvanised. The supplier can ship in bulk cartons up to 25 kg each, palletised on wood, with a monthly capacity of 1 000 tons.

Typical industry practice for these fasteners uses carbon‑steel grades 4.8 and 8.8 for structural steel connections, where class 8.8 bolts normally achieve a tensile strength of about 800 MPa (typical). Stainless‑steel variants provide corrosion resistance comparable to 304 stainless (typical) and are chosen for marine or chemical environments. The HDG coating commonly applied in the market has a thickness around 80 µm (typical), offering long‑term protection against rust.

These bolts are widely used in structural steel frames, metal building kits, oil‑and‑gas rigs, wind‑energy towers and automotive assemblies. Importers in North America, Europe and Asia often request FOB or CIF terms, with the minimum order set at 500 kg per specification. Handan Daoning Fasteners Co., Ltd. invites buyers to confirm the exact size, material, grade and surface finish required, and to provide drawings or samples for non‑standard items.

Handan Daoning Fasteners Co., Ltd. is located in Handan, Hebei Province, China (postal code 056000). The company is listed with a harbour‑level trust tier, indicating that it has passed basic verification checks, although its response rate is currently recorded as 0 % and average response time is not available.

The supplier advertises a production capability of up to 1 000 tons per month and offers a full range of fastener services, including material testing, surface‑treatment reports and free sampling on request. No specific certifications, client lists or revenue figures are disclosed in the listing, so buyers should request copies of any required test certificates directly from the supplier.
