Product Details

Ashok Industries is the biggest manufacturer for larger high tensile bolts & nuts in India, we have a monthly production of over 300 tons in bigger sizes from M-24 to M-64 in 8.8 and 10.9 grade. These bolts & nuts are used in energy sector like wind, solar, thermal and hydro energy. We are the pioneers in manufacturing critical bolts & nuts for the wind energy sector in India. These bolts & nuts are manufactured only by hot forging process and we have the complete list of machines in our factory to manufacture these bolts & nuts.

These bolts are forged on heavy upsetting machines and are then machined on latest CNC machines in our factory, we also do the heat treatment in our factory using an advanced polymer quenching technology which gives a very fast rate of cooling for these bolts & nuts in heat treatment, the result is a perfect martensite after hardening and gives perfect results after tempering as per standard requirement.

These high tensile bolts in bigger diameters can also be thread rolled after heat treatment to get better fatigue life for these bolts. Thread rolling after heat treatment results in a better life of the bolting and removes any concern of carburising or decarburising in heat treatment process.
