Class 12.9 Hex Head Bolts and High Tensile Grade 12.9 Allen Bolt manufacturer in India

12.9 Metric Bolts are headed externally threaded fasteners which is used to keep two objects usually metal or wood, in a fixed position it is relative to one another. Grade 12.9 Bolts is a high tensile bolt. It is available which us in different shapes and types. 12.9 Grade Bolt is paired with the internal thread of nuts to stay in place and to ensure the desired level of tension in the bolted joint. The minimum ultimate tensile strength of the Grade 12.9 Bolt is about 1242 Mpa or 180,000 PSI, which makes them the highest grade of bolts. 12.9 Allen Bolt is a bolt with a hexagonal socket in its head that is designed to be used with an Allen wrench to drive them into material and secure them into a structure. It is essential to the crank and remains in it when the crank is unfastened from the spindle. 12.9 Hex Head Bolts are large bolts with a six-sided head it used to fasten wood to wood, or metal to wood. Unlike carriage bolts, it will have a tendency to spin as it is tighten so it needs to hold the bolt head with a socket or a wrench to tighten the nut with a second wrench. It has a smooth shank and a small thread. High Tensile Bolts 12.9 Grade are low-carbon, or steels at the lower end of the medium-carbon range, it has an additional alloying ingredients in order to increase their strength, wear properties or especially its tensile strength. The alloying elements include chromium, molybdenum, manganese, nickel, silicon, and vanadium. It is a good, strong, long-lasting steel bolts.
