Import Din931 — Buy in Bulk from Supplier in China

The DIN931 bolt is a hexagon‑head, full‑thread fastener conforming to the DIN 931 standard. It is supplied in strength classes 8.8, 10.9 and 12.9, each delivering a minimum yield strength of 640 MPa, 830 MPa and 1040 MPa respectively. The bolts are forged from carbon steel and can be delivered with a zinc‑plated surface for improved corrosion resistance. Shanghai Xinluo Enterprises Devlopment lists the product as meeting ISO quality standards.

In the fastener market carbon‑steel DIN931 bolts are normally heat‑treated to achieve the specified tensile properties and are toleranced to class 6g per ISO 965. Typical diameters range from M6 to M64 with lengths between 20 mm and 300 mm, allowing selection for a broad spectrum of joint designs. The hex head dimensions follow the DIN standard, providing a wrench size that matches the bolt’s nominal diameter. Such specifications make the bolt interchangeable with other DIN 931 and ISO 4014 fasteners.

These bolts are widely used in construction frames, automotive chassis, and heavy‑duty machinery where joint safety is critical. Importers such as OEM manufacturers and contract fabricators often require small batches, and Shanghai Xinluo notes low minimum order quantities and acceptance of L/C or T/T payment. The supplier also references ISO certification, which buyers should verify before placing an order. Trade can be arranged under any Incoterm agreed between the parties.
