Import Bolt — Buy in Bulk from Supplier in India

Sterling Industry manufactures and supplies bolts in both inch and metric dimensions, with nominal diameters up to 2 inches for standard bolts and up to 2.5 inches for stud bolts. The product range addresses industrial fastening requirements across construction, manufacturing, automotive assembly, and heavy machinery sectors. Material specification is described as industrial-grade, with corrosion-resistant coating or surface treatment applied to extend service life in exposed environments. Custom options are stated as available for non-standard lengths, thread pitches, or head configurations upon request.

The product description references high tensile strength as a performance characteristic, though specific grade designations such as ASTM A325, ISO 898-1 class 8.8, or SAE J429 Grade 5 are not stated. For carbon steel bolts, typical tensile strength ranges are 400-800 MPa for medium-carbon grades and 800-1200 MPa for alloy-steel heat-treated grades. Corrosion resistance is commonly achieved through zinc electroplating (5-12 micrometres), hot-dip galvanising (45-85 micrometres), or mechanical zinc plating, depending on the service environment and specification. Thread forms are presumed to be unified coarse (UNC) or metric coarse as standard, with fine-pitch variants available on custom order.

Buyers evaluating Sterling Industry bolts should determine whether the application requires structural certification, such as EN 14399 for preloaded bolted connections in steel construction, or automotive approval to IATF 16949 traceability requirements. The supplier states ISO and BIS certifications at the enterprise level, though specific product test reports or mill certificates are not detailed in the source material. Packaging for export is described as secure for international shipping, with FOB and CIF Incoterms offered. Minimum order quantities are described as flexible, but exact figures must be confirmed directly with the supplier.

Sterling Industry is located at 2 Dhaamkanta Road, Mujessar, Faridabad 121007, Haryana, India. Faridabad is an established engineering and fastener manufacturing cluster in the National Capital Region, with access to cold-forging, thread-rolling, and heat-treatment infrastructure. The supplier holds an imported supplier tier and harbor trust tier, indicating platform verification without implying manufacturing scale or export volume. The response rate is recorded at 0.00 percent with zero average response hours, so buyers should initiate direct contact to assess current operational status and inquiry handling.

The source description attributes flexible MOQ, ISO and BIS certifications, FOB and CIF terms, and secure export packaging to the supplier, though no specific MOQ figures, certificate numbers, or packaging specifications are provided. No client list, revenue figures, employee count, or years in operation are stated. Buyers should request a supplier capability assessment, including machinery list (cold header capacity, thread roller count, heat-treatment furnace type), in-process quality control protocols, and third-party audit status before relying on the supplier for critical applications.
