Friction bolt
Shandong Tongrui Mining Technology Co., Ltd. supplies a roll‑formed friction bolt made from high‑strength steel and finished with a corrosion‑resistant coating. The bolt features a tapered tip that permits smooth insertion into drilled holes and provides immediate grip. Its design is intended for underground support where load‑bearing capacity is critical. The product description lists the bolt as suitable for mining, tunnelling and construction projects.
In the mining industry friction bolts are commonly supplied in diameters ranging from 18 mm to 25 mm and lengths between 1.5 m and 3.0 m, with a typical yield strength of 400 - 500 MPa for high‑strength carbon steel. Standard practice includes a zinc‑rich coating to improve corrosion resistance in harsh underground environments. Roll‑forming is the usual manufacturing method, delivering consistent thread‑free shank geometry. These typical specifications complement the supplier’s own claim of high‑strength steel construction.
Buyers such as underground mine operators, civil‑engineering contractors and tunnel‑construction firms use the bolt for rock reinforcement and roof support. The supplier states that minimum order quantities can be adjusted to project size and that shipping terms include FOB and CIF. Certification to ISO and SGS standards is mentioned, so purchasers should request the relevant test reports before finalising the contract.

Sourcing Friction bolt from Shandong Tongrui Mining Technology Co., Ltd. - China Import Guide
Before placing an order, verify the steel grade and request the material test report to ensure the bolt meets the required yield strength. Ask for copies of the ISO and SGS certificates and confirm the dimensions and coating type match your project specifications. This due diligence helps avoid mismatches that could affect underground support performance.
Logistics for this supplier are arranged on FOB or CIF terms; however, exact lead times are not published, so you should ask the supplier for the expected production and delivery schedule. Clarify the incoterm that best fits your supply chain and discuss acceptable payment methods such as T/T or L/C. Aligning these details early reduces the risk of shipment delays.
For quality assurance, consider a third‑party inspection at the loading port and request a pre‑shipment test report covering tensile strength and coating thickness. Ensure that the supplier can provide a mill test certificate and a packing list for customs clearance. These documents are essential for a smooth import process.
