#8.8 grades

We are reputed manufacturer, supplier and exporter of T bolts for heavy industry, wind energy sectors, marine, ship building, oil and wind energy. Available in 10.9 and 8.8 grades. T bolts are special application bolts which are generally manufactured as per customer drawing and specification. Unlike hexagon bolts, T bolts are T shaped . We offer T bolts & nuts in 8.8 and 10.9 grade, the choice of the grade depends upon the application and requirement of the customer. The grades 8.8 or 10.9 have separate mechanical characteristics which are defined in the above sheet.

We manufacture T Bolts in bigger diameters from M-20 to M-64 in diameter in class 8.8 and 10.9, stocks are not available as these are generally made as per drawing, we are manufacturing T 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.

We are renowned manufacturer, supplier and exporter of structural bolts in India. Structural bolt assembly is used in both preloaded and non-preloaded applications. These high tensile bolts are Available in 10.9 grades and 8.8 grades. The structural Bolts following EN 14399-4 and DIN 6914 is to use thinner nuts and shorter thread lengths to obtain the required ductility by plastic deformation of the threads within the nut. The structural bolt assembly is used in both preloaded and non-preloaded applications. Sturctural bolts charecteristics:  are Large under-head surface, Less surface pressure, Enables preloading, Improved fatigue strength, Defined friction properties. Application of  structural bolts: It is  used in heavy industries like chemical, wind energy, ship, oil and wind energu sector

Bigboltnut are a renowned manufacturer, supplier and exporter of high tensile structural bolts. Structural bolt assembly is used in both preloaded and non-preloaded applications. These bolts are available in 8.8 and 10.9 grades and its depends on our customer requirement. Structural bolts are used in connection between two towers, marine , ship building , wind enery sector . and also manufacturing EN 14399-4 10.9 bolts & nuts in hot dip galvanised condition.
