We are the Roll-fast leading fastener and component suppliers to Cross country pipeline. We have wide range of products as per requirements. Our fasteners are used in Chemical, Oil and Petrochemical Industries for high pressure flange connections. 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 and other piping system requirements. 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.
