Import 5/8" Stud Bolt — Buy in wholesale FOB from Supplier in India

The 5/8 inch stud bolt from KPS Metal Components is a double-ended threaded fastener manufactured in Chennai, Tamil Nadu, India. It is produced in Stainless Steel 304 and Carbon Steel Grade B7 variants, materials selected for their tensile performance and corrosion resistance in demanding environments. The 5/8 inch nominal diameter refers to the thread major diameter, a standard imperial sizing compatible with ASME B18.2.1 heavy hex nuts. These stud bolts serve critical flange connections in oil and gas pipelines, petrochemical refineries, and heavy industrial construction where joint integrity under pressure cycling is paramount.

Grade B7 stud bolts are quenched and tempered alloy steel fasteners rated for service temperatures from -20°F to 1000°F (-29°C to 538°C), making them suitable for high-temperature pressure vessels. Stainless Steel 304 offers superior resistance to oxidizing media and is typically specified for cryogenic or corrosive service where carbon steel would degrade. The double-ended design features equal thread lengths on both ends with an unthreaded shank in between, allowing proper nut engagement while maintaining shank ductility under tensile load. Surface finishes range from plain black oxide to hot-dip galvanizing or PTFE coating, each selected to match the gasket and flange material pairing.

Buyers of this stud bolt include EPC contractors for refinery projects, pipeline construction firms, and maintenance procurement teams for power generation facilities. The product is typically supplied with matching heavy hex nuts and hardened washers as a complete bolting set. KPS Metal Components lists this item with material grade options but does not publish confirmed MOQ, lead time, or unit pricing in the available data. Importers should confirm thread pitch (UNC coarse series is standard for 5/8 inch), thread class (2A/2B or 3A/3B fit), and whether full material test reports including tensile strength and hardness values are available with each lot.

KPS Metal Components is based in Chennai, Tamil Nadu, India, with operations in a major South Indian manufacturing and port hub. The supplier carries a harbor trust tier classification, which indicates a baseline verification status on the platform. The response rate is recorded at 0.00 percent with zero average response hours, meaning no response data is available from recent buyer interactions. This absence of response history should factor into buyer communication planning.

The company profile does not disclose founding year, factory size, annual revenue, or named client references. KPS Metal Components positions itself as a manufacturer and exporter of industrial fasteners including stud bolts in alloy and stainless steel grades. The listing emphasizes material grade availability and application sectors rather than proprietary manufacturing capabilities or inventory depth. Buyers should verify whether KPS operates its own forging and threading facilities or sources finished blanks, as this affects lead time flexibility and material traceability.
