Metallum Overseas manufactures, supplies and exports precision-engineered Hexagon Flange Bolts for industrial valve assemblies, piping systems, flanged connections and mechanical fastening applications. A hexagon flange bolt combines a hexagonal bolt head with an integrated flange that provides a wider bearing surface when tightening the fastener.
Our hexagon flange bolts are available in stainless steel, duplex steel, super duplex steel, Inconel, Monel, Hastelloy, titanium, Alloy 20 and other suitable engineering materials. Bolts can be supplied in metric and UN sizes with different surface treatments according to application requirements, applicable standards and project specifications.
As a Hexagon Flange Bolt Manufacturer, Supplier and Exporter in India, Metallum Overseas provides precision-engineered fasteners for industrial valve, piping and mechanical assembly applications. The integrated flange provides a larger bearing area under the bolt head and can help distribute clamping load across the mating surface.
We can supply hexagon flange bolts according to applicable standards, customer drawings and technical specifications. Material selection, thread dimensions, bolt size and surface treatment can be specified according to the requirements of the valve, piping system or mechanical assembly.
Hexagon flange bolts are available in Metric M8 to M48 and UN 1/4 to 4 inch sizes based on the reference product range. They are suitable for fastening applications where secure clamping and a broad bearing surface are required.
Metallum Overseas can supply hexagon flange bolts in different materials and surface finishes for industrial environments. Bolts can also be supplied according to required dimensions, thread specifications, material standards and customer drawings.
