Grade 12.9 Bolt is a high tensile bolt that has a diameter of 12.9 mm and the lengths vary from 20mm to 200mm based on the application requirement. Navstar Steel is a leading manufacturer and supplier of the Grade 12.9 Bolt in different types and shapes. There are studs, hex bolts, U bolts, T bolts and many other types in this grade.
The Class 12.9 Threaded Bar or the stud is a metallic rod with male threads on both sides. This is a useful component when two other components with female threads have to be fitted together. The Class 12.9 Hex Nut is the most commonly used shape of the nut. These have a hexagonally shaped exterior that provides maximum grip upon tightening the nuts onto bolts.
The ASME SF568 High Tensile Grade 12.9 Stud Bolts belong to the specification SF568 and the minimum tensile strength is 1220MPa with 1100MPa minimum yield strength. The Grade 12.9 Hex Head Bolts as well as other types of bolts are used in some of the high tensile applications such as the engine parts, motor casings and others. Please feel free to contact us for more information on the Grade 12.9 Hex Bolts, u bolts, t bolts and other types of bolts with the price catalog.
