Star Steel Alloys - Stainless Steel Pipes, Stainless Steel Tube Manufacturers, Seamless Pipe & Tube, Welded Pipe & Tubes Suppliers & Exporter in India

High Tensile Fasteners are used in extensive stress applications. The high tensile strength is needed for these fasteners to hold on components under high strength. Navstar Steel is a leading High Tensile Fasteners manufacturer in India and we manufacture all different types, grades and scales of high tensile fasteners.

High Tensile Bolt Material, M8 High Tensile Bolt Strength, Check Updated price List of High Tensile Steel Threaded Rod

There are different grades such as 10.9, 8.8, DIN 933 and 12.9 grades. There are also many standards such as the IS1364, IS1363, DIN EN ISO 4014 and others. These standards define the sizes from 20mm to 100mm in the fastener sizes. The different types such as HT Nut Bolt are used for different purposes. The nut bolts are connected through threads.

The bolts are externally threaded and the nuts are internally threaded. The bolts have male threads that go along with the female threads on the nuts. The M10 High Tensile Studs are essentially metallic rods that have threads on both ends. These are also around 10mm in diameter as the M10 nomination suggests. There are different nominations such the M8 as well. The High Tensile Bolt Material can vary in composition according to the material grade. Most of these are chromium nickel and nickel copper alloys as they hold high tensile strength. The M8 High Tensile Bolts are around 8mm in diameter and can range in different lengths and grades of material. Please contact us for more information on the pricing of these high tensile fasteners and the product information.
