Import Din315 Wing Nuts — Buy in Bulk from Supplier in China

Handan Daoning Fasteners Co., Ltd. offers DIN315 wing nuts that meet the ASME B18.6x and DIN315 standards, with nominal sizes ranging from #3 to 3/4" and metric equivalents M4‑M24. The nuts are manufactured from carbon steel, alloy steel, stainless steel or brass, and are supplied in SAE J995 grade 2 with mechanical classes 4, 5 and 6. Thread options include metric (M), UNC and UNF, and surface finishes cover plain, zinc‑plated (clear, blue, yellow or black), black oxide, nickel, chrome and hot‑dip galvanised. Bulk packaging is in cartons up to 25 kg placed on wood pallets, and the factory can produce up to 1 000 tons per month.

In typical industrial use, wing nuts are chosen for their ease of hand‑tightening and for applications where frequent adjustments are required. Carbon‑steel variants in class 4 provide a shear strength of roughly 300 MPa (typical), while stainless‑steel versions deliver corrosion resistance similar to grade 304 (typical). The HDG coating often applied to these fasteners usually has a thickness of about 80 µm, offering protection comparable to zinc‑plated finishes.

These wing nuts are widely employed in structural steel assemblies, metal building frames, oil‑and‑gas equipment, tower‑and‑pole installations and wind‑energy structures, as well as in automotive and home‑decorating projects where quick removal is advantageous. The minimum order is listed as 500 kg per specification, and buyers can select from FOB, CIF, CFR, CNF, EXW, DDU or DDP terms. Prospective importers should communicate the exact size, material, grade and finish needed, and supply any relevant drawings for non‑standard requests.

Handan Daoning Fasteners Co., Ltd. operates from a facility in Handan, Hebei Province, China (postal code 056000). The company holds a harbour‑level trust tier, which means basic verification has been completed, but the listed response rate is 0 % and no average response time is recorded.

The supplier claims a monthly output of up to 1 000 tons and provides a range of fastener‑related services, such as material testing, surface‑treatment certification and free sample provision. No explicit certifications, client references or financial data are included in the listing; buyers should request any needed documentation directly from the supplier.
