Buy & Import High Torque Rockbolt Nut from OK Engineering Works - Wholesale Supply

High Torque Rockbolt Nut supplied by OK Engineering Works is a fastener made from high‑strength steel grade 8.8 with a hot‑dip galvanised finish, intended for underground mining support. The nuts are available in metric sizes M20 through M30 and meet ISO 898 mechanical property standards. They are described as suitable for high load conditions in rock‑bolt assemblies.

Industry practice for grade 8.8 fasteners calls for a minimum tensile strength of 800 MPa and a yield strength around 640 MPa, which matches the product’s design. The galvanised coating provides corrosion resistance in moist underground environments, a common requirement for mining hardware. Typical hardness for such nuts lies between 170 HB and 210 HB, ensuring durability.

The nuts are installed in underground mines, tunnel excavation projects and other ground‑support structures where high shear loads occur. Main buyers are mining contractors and tunnel construction firms that import fastening hardware in bulk. The listing does not disclose minimum order quantity, lead time or payment terms, so purchasers should request these details directly from OK Engineering Works. Discuss packaging preferences, such as bulk bags or palletised units, and confirm Incoterms before placing an order.

Frequently Asked Questions About High Torque Rockbolt Nut from OK Engineering Works
The nut is made from high‑strength steel grade 8.8. This grade provides a minimum tensile strength of 800 MPa and is widely used in mining fasteners.

Sourcing High Torque Rockbolt Nut from OK Engineering Works - India Import Guide

Before committing to a purchase, buyers should obtain a certified test report confirming the nut’s tensile strength, yield strength and hardness, as these mechanical properties are critical for safe underground support. Request documentation of the hot‑dip galvanising thickness and a visual inspection of the coating to ensure adequate corrosion protection. Verifying that the dimensions conform to ISO metric thread tolerances will prevent fitting issues during installation.

Logistics for the fasteners typically involve sea freight from a port in India, with Incoterms such as FOB or CIF negotiated per contract. As the listing does not disclose lead times, the importer should ask OK Engineering Works for current production schedules and estimated shipment dates. Payment arrangements are usually made via irrevocable letter of credit or advance payment, depending on the buyer’s risk profile.

Importers are advised to arrange pre‑shipment inspection by an accredited third‑party agency to verify material grade, mechanical properties and coating condition against the agreed specifications. Upon arrival, a receipt inspection should confirm packaging integrity, correct part numbers and the absence of damage. Essential documents include the assay certificate, coating thickness report, packing list, bill of lading and any applicable quality certificates.
