HIGH TENSILE Big BOLTS/Nuts manufacturing for energy sector wind/solar/thermal/hydro energy

High Tensile Bolt 8.8 9.8 10.9 12.9 Grades manufacturing, Galvanized High Tensile Bolts Manufacturers, 304 stainless High Tensile Bolts factory

· GalvanizedBolts Nuts

bigger sizes M24 to M64 (8.8 10.9) grade factory monthly production about 300 tons, hot forging process bolts & nuts manufacturing for the wind energy sector.

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.
