Import Full Thread Bar Bolt — Buy in Bulk from Supplier in China

The Full thread bar bolt offered by Shandong Tongrui Mining Technology Co., Ltd. is an industrial fastening component designed for ground support in mines, tunnels and slopes. It features a fully threaded shank that enables uniform load distribution along its length. The bolts are manufactured from carbon steel and comply with ISO 898‑1 tensile standards. Available lengths span from 1 m to 6 m, which is typical for this class of bolt, allowing adaptation to various project depths.

The fully threaded design eliminates the need for head reinforcement and simplifies installation with standard drilling equipment. Typical diameters are 16 mm with a standard metric M12 thread pitch, matching common anchoring rigs. A zinc coating is commonly applied to improve corrosion resistance in underground environments. These characteristics give the bolt a typical tensile strength of around 400 MPa, suitable for high‑stress applications.

Buyers such as mining contractors, civil‑engineering firms and construction companies use these bolts for slope stabilization, rock bolting and structural reinforcement. The supplier can provide the bolts on FOB or CIF terms, though exact trade conditions should be confirmed directly. Certification documents, such as material test reports, can be requested before shipment. Order quantities are flexible, but the minimum order quantity is not disclosed and must be verified with the supplier.
