We are renowned manufacturer, supplier and exporter of high tensile fasteners in India. Available in 8.8, 10.9, 12.9, B7, B7M, B16, L7 and L7M grades. Big bolt nut is the biggest manufacturer for larger diameter high tensile fasteners & 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 high tensile fasteners are used in energy sector like wind, solar, thermal and hydro energy.
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 SQF sealed quench heat treatment furnace from DOWA Japan, the heat treatment furnace is SCADA controlled and provides 100% repeatability batch after batch. The heat treatment result is a perfect marten site after hardening and gives perfect results after tempering as per standard requirement.
These high tensile fasteners 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.
We manufacture High tensile Bolts in bigger diameters from M-20 to M-64 in diameter in class 8.8 and 10.9, stocks are readily available and we are manufacturing bolts diameter from M-20 to M-64 diameter, we also offer ISO threads and nominal thread fitments. The biggest advantage of our manufacturing is that we do thread rolling after heat treatment, this provides for extra torque and extra fatigue strength by more than 50% and also ensures stronger unbroken fibre lines and a very fine marten site in core and in the threads of the bolts
