Import B7 Threaded Rod — Buy in Bulk from Supplier in India

Singhania International Limited manufactures B7 threaded rod from AISI 4140 or 4142 alloy steel at their Ludhiana facility in Punjab, India. The product covers diameters from 1/4 inch to several inches, suitable for structural and mechanical fastening where high tensile strength is required. The rods are produced to ASTM standards with a corrosion-resistant finish extending service life in demanding environments. The supplier is located at C-25, Phase-1, Focal Point, Dhandari Kalan, Ludhiana 141010, Punjab, India.

AISI 4140 and 4142 are closely related chromium-molybdenum steels with nearly identical mechanical properties; the 4142 variant carries slightly higher carbon content at 0.40-0.45% versus 0.38-0.43% for 4140, both within the ASTM A193 B7 envelope. Standard heat treatment involves austenitizing, quenching in oil, and tempering to achieve the required strength and hardness combination. Typical tensile strength for properly heat-treated B7 material reaches 125 ksi minimum with yield at 105 ksi, though the source description does not cite specific mechanical test values for this supplier's output.

Primary applications span construction, automotive assembly, machinery mounting, and general engineering where threaded rod serves as adjustable tension members or anchor bolts. The full-threaded format allows nuts to be positioned anywhere along the length, offering flexibility in field adjustment. Buyers in infrastructure and industrial equipment sectors represent the core market. The supplier mentions flexible order quantities, though no specific MOQ is published, and references ISO certifications without stating which standard or certifying body.

Singhania International Limited is based at C-25, Phase-1, Focal Point, Dhandari Kalan, Ludhiana Ludhiana 141010, Punjab, India. The supplier holds a harbor trust tier on the platform, with a published response rate of 0.00% and no recorded average response time. The listing does not state year of establishment, number of employees, production capacity, or annual revenue. No specific ISO certificates are identified by standard number or accreditation body.

The company profile positions itself as offering flexible minimum order quantities and global shipping, though concrete logistics capabilities are not detailed. Buyers should conduct direct due diligence on manufacturing scope, whether the Ludhiana facility performs heat treatment in-house or outsources this critical process, and what inspection equipment is available for thread and mechanical testing. The reference to ISO certification should be verified with current certificate copies before quality-critical orders are placed.
