Bolts made of grade 12.9 are high in strength. It has a min yield strength of 1100 MPa and a min tensile strength of 1220 MPa. The Grade 12.9 Bolt is used for some of the heaviest jobs like securing an engine. The 12.9 grade bolts suppliers supply these products to be used in high stress environments. In fact, High Tensile Bolts 12.9 Grade is the highest class for metric bolts. This can be understood by their tensile strengths, which 120 percent more for 12.9 High Tensile Bolts than grade 10.9 bolts.
The Grade 12.9 Bolts are threaded fasteners that come with external male threads which need to match the pre-formed female thread, like nuts. The Class 12.9 Bolts are known for their long life cycle and are easy to install and uninstall. The 12.9 Bolt is made of carbon steel and can be customised to different shapes and sizes.
