HT Hex Bolts and ASME SF568 Threaded Rod Manufacturer in India
It is common to use either alloy steel or carbon steel grades for applications involving general engineering. While carbon steels have high hardness and are tough, the other mechanical properties of alloy steel High Tensile Fasteners tend to be much superior to the former. To standardize the production process of all fasteners, the use of standards or specifications is common practice amongst most high tensile fasteners manufacturers in India. Standardizing fasteners proves to be beneficial on several counts.
Primary amongst them is the safety requirements, especially if said fasteners are to be used in engineering applications. Fastener failure can have detrimental effects in various environments, causing environmental bio-hazard or even fatal human casualties. Following standardized specifications to produce a High Tensile Stud involves confirming both the mechanical, as well as chemical requirements of the nine classes of both alloy steel and carbon steel. The other benefit of having a standard fastener is durability because it fits the application by giving the material a snug fit. Amongst the nine classes mentioned before, fasteners such as the High Tensile Nut Bolt belonging to both classes, that is 8.8.3 and 10.9.3 need to meet a fixed set of requirements. Resistance to atmospheric corrosion is the most important characteristic of these fasteners. In fact, the atmospheric resistance to corrosion exhibited by the SF568 HT Heavy Hex Nuts tends to be far superior to carbon steel fasteners, produced without adding copper to their alloy. This is why it is possible to use these fasteners without any surface treatment or coating. The weathering characteristics of the ASTM F568 High Tensile Double Ended Studs in property classes 8.8.3 and 10.9.3 are similar to steel grades that belong to specification A 588.
