High Tensile Bolts: 8.8/10.9/12.9 Grade Strength for Heavy-duty Applications

HT bolts, short for high - tensile bolts, are widely recognized for their superior strength and reliability in fastening applications. These bolts are fabricated from high - grade alloy steels, often with a complex heat treatment regime that includes multiple quenching and tempering steps to refine the microstructure and enhance mechanical properties. HT bolts come in various grades, such as 8.8, 10.9, and 12.9, with each grade corresponding to different levels of tensile and yield strength. They are extensively used in industries where high - strength connections are required, such as in the assembly of industrial machinery, railway infrastructure, and marine vessels. In the railway industry, HT bolts are used to secure rail tracks and components, ensuring the safety and stability of train operations. BOBFAST’s HT bolts are produced with strict quality control at every stage, from raw material selection to final product inspection, guaranteeing consistent performance and meeting the demanding requirements of global customers.
