What is Grade 8 bolts ?

Grade 8 bolts These Grade 8 bolts are made up of a chemical composition that is medium carbon alloy steel. These bolts are treated with heat in an atmosphere where carbon is controlled. These Grade 8 bolts are comparatively stronger and thus comparatively better than the grade 5 that are available. These Grade 8 bolts have six radial lines in total above the bolt.

These Grade 8 bolts also have great torque strength as they have the carbon present in them. These bolts are known to have great strength as well as great tensile strength because of which they are used in a large number of industrial applications. They are basically used in applications where the stress is a factor along with heavy load bearing.

Grade 8 Yellow Zinc Fasteners – Nuts, Washers, Bolts & Screws. These fasteners are heat treated to harden the metal. Grade 5 Zinc Fasteners are partially treated, whereas our stock of Grade 8 Yellow Zinc fasteners are thru heated to maximize its hardness. Exporter.

Sumit Impex is well known to manufacture high quality Grade 8 bolts. They keep all the industrial standards, guidelines, rules and regulations in mind before manufacturing the product so as to ensure a good quality product is manufactured.

These Grade 8 bolts could be available in different lengths, sizes as well as dimensions depending upon the specifications or requirements provided by the user or the need of the applications. Because of the properties and the characteristics that these fasteners have they are used in a wide variety of industrial applications such as aerospace, the marine industry, in the military, etc.

Application Industries

These material are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthrough the origins of stainless steel lies in a lucky accident. From the smallest part of zipper to the largest building skyscraper, stainless steel is an essential part of modern life.Stainless steel’s strength, resistance to corrosion and low maintenance make it the ideal material for a wide range of applications. It is also has a long life cycle and is 100% recyclable.
