Import Din933 Hexagon Bolt — Buy in wholesale FOB from Supplier in China

DIN933 hexagon bolts from Ningbo Yi Pian Hong Fastener Co., Ltd. are full-threaded metric fasteners ranging from M4 to M100, manufactured to DIN, ANSI, GB, JIS, and GOST standards. Available in carbon steel, stainless steel, and alloy steel, with surface treatments including black oxide, zinc plating, yellow zinc plating, hot-dip galvanizing, and Dacromet. These bolts are designed for structural and bridge engineering applications where high tensile strength and corrosion resistance are required. The supplier confirms compliance with international fastener standards but does not publish certified test reports.

Material grades range from 4.8 to 10.9, with typical mechanical properties aligned with ISO 898-1 for carbon steel fasteners. Standard tensile strengths are 400 MPa for grade 4.8 and 1040 MPa for grade 10.9. Surface treatments follow ISO 4042 for plating thickness and ASTM B633 for zinc coatings. Dacromet finishes provide salt spray resistance exceeding 500 hours, a typical benchmark for industrial applications. Packaging is standardized at 25 kg per box, with 36 boxes per pallet totaling 900 kg, suitable for containerized export.

These bolts are purchased by engineering contractors, machinery manufacturers, and infrastructure developers in Europe, North America, and Southeast Asia. Buyers commonly specify DIN933 for structural connections requiring full-thread engagement and high preload capability. The supplier accepts custom designs and logo marking, and offers free samples upon request, though express shipping costs are borne by the buyer. Lead time is 30 to 45 days for standard sizes, and 35 to 60 days for non-standard requests. Payment terms are typically T/T or L/C, with Western Union accepted for sample fees.
