Fasteners for Storage tank

Our fasteners are used in Chemical, Oil and Petrochemical, Waste Water, Food Industries for connection of flanges & Doors. Flanges are fastened together with the help of stud bolts and nuts. The nuts used in the tightening of flanges are generally of hexagon or heavy hexagon type depending upon the pressure. Flange connections are also fastened with traditional solutions like Hex Bolts. Hex bolts are very similar to stud bolts in terms of threading but have a forged hexagon head. However, stud bolts are preferred over hex Bolt because during tightening and toque application, studs do not twist.

ISO 4014 is primarily the dimensional standard for hex bolts. This defines the Dimensional requirement primarily i.e., length and the diameter of Bolt to be used for the tightening of flanges. Whereas ISO 965-1 defines the threading requirements.
