Import Big Washer — Buy in Bulk from Supplier in India

Bon Engineers manufactures this Big Washer at its facility in Rajkot, Gujarat, for heavy-duty mechanical assemblies where load distribution and structural integrity are critical. The washer is produced from high-strength carbon or alloy steel to customer-supplied drawings, with dimensions and tolerances customised to each order rather than held as standard stock sizes. Surface finish options include plain, zinc-plated, or hot-dip galvanised treatments to suit corrosive or exposed environments.

The material specification typically falls within ASTM F436 or IS 6649 grades for structural washers, with hardness ranging from 35 to 45 HRC depending on the application and the customer's fastener assembly requirements. Thickness tolerance for washers of this class is usually plus or minus 0.25 mm on nominal dimensions up to 50 mm outer diameter, and plus or minus 0.40 mm above that threshold. Bon Engineers offers these washers in quantities from small trial lots to bulk production runs, with packaging in oiled paper or plastic-sealed cartons to prevent corrosion during transit from Gujarat's industrial corridor to port facilities at Mundra or Kandla.

Primary buyers include infrastructure contractors, automotive OEMs, and heavy machinery manufacturers who require certified washers for bolted joints in high-stress equipment. The product serves applications such as structural steel connections, engine mounting assemblies, and railway rolling stock maintenance. Importers should request material test certificates and dimensional inspection reports before finalising orders, as custom manufacture means each batch varies according to the customer's engineering specification.

Bon Engineers operates from Plot No. 69 in the Vavdi Industrial Area of Rajkot, Gujarat, a city established as one of India's principal manufacturing centres for forged and machined industrial components. The supplier's address places it within the 150 Ring Road corridor, a zone dense with metalworking and engineering subcontractors that serve domestic infrastructure projects and export markets alike. No information is provided about the year of establishment, workforce size, or annual turnover, and these details should be verified directly with the company.

The listing carries a Harbor trust tier and shows a response rate of 0.00 percent with zero average response hours, which indicates either a newly registered profile or incomplete engagement metrics on the platform. Buyers should treat this as an unverified communication record and confirm the supplier's current production capacity, quality certification status, and export experience before committing to purchase. The company profile does not list specific industry certifications, accredited testing facilities, or named client references, so due diligence on manufacturing capability and previous export performance is essential.
