The item is a square‑head bolt manufactured by Singhania International Limited in Ludhiana, India. It is fabricated from carbon steel to Grade 8.8, with optional Grade 10.9 for higher strength requirements. The bolt features a four‑sided head that provides a larger bearing surface for torque application.
Grade 8.8 bolts typically deliver a minimum tensile strength of 800 MPa, while the 10.9 variant reaches 1000 MPa, meeting common fastener standards for structural and mechanical assemblies. The square head geometry is advantageous in applications where a wrench can engage multiple faces, reducing slippage compared with hex heads. Standard finishes include galvanised zinc coating or black oxide for corrosion resistance, both widely accepted in construction and automotive sectors. Dimensions such as diameter and length follow the metric thread series M6 to M24 and lengths from 20 mm up to 200 mm, which are typical ranges for this fastener type.
Primary users are contractors, equipment manufacturers and maintenance teams that need a secure, non‑rotating fastener for timber, rail or steel structures. The bolts are packed in bulk cardboard boxes or sealed poly‑bags, suitable for container loading and protected against moisture. Shipping terms can be arranged as FOB, CIF or EXW depending on the buyer’s preference, but the listing does not state the exact MOQ, lead time or price, so those should be clarified with the supplier. Requesting a material test certificate and a dimensional inspection report is advisable to ensure compliance with the required grade.

Before committing to a purchase, confirm the supplier’s harbour‑tier verification, business registration and the existence of a current mill test certificate for the selected grade. Verify that the bolt dimensions, head size and finish match your engineering drawings, and request a sample if possible to assess fit and finish. Also ensure that the packaging method will protect the bolts from moisture during transit.
Logistics for the square head bolt are usually handled via container shipping, with the supplier able to quote FOB, CIF or EXW terms. Clarify the expected lead time, which may depend on production scheduling and order size, and agree on payment terms such as a 30 % deposit with the balance payable against shipping documents. Align the incoterm with your responsibility for freight, insurance and customs duties.
Upon receipt, conduct a dimensional inspection of the head width and thread pitch using calibrated tools, and perform a tensile test on a sample to confirm the grade’s mechanical properties. Retain the mill test certificate and any third‑party inspection reports for customs clearance and future quality audits. Implement a routine inspection protocol for each shipment to maintain consistent product performance.
