A U-bolt is a fastener that has been produced in the shape of the letter U with screw threads on both ends of the shaft.Stainless Steel Square U Bolts are primarily used to support pipes through which fluids and gasses pass. Square Bend Ss U-Bolts are also used to hold ropes together.The SS U-Bolts Dimensions would be described by the size of pipe it was supporting.

Besides supporting pipes and holding ropes together, SS U Bolts are used in a broad spectrum of applications that involve clamping any kind of tubing or round bars.Stainless Steel U Bolt Manufacturers define these fasteners with the help of Five elements. These five elements include material use to construct these U bolts, rod diameter, inside length, diameter between the legs or inside diameter and thread dimensions.In order to have a high working performance in different environmental conditions, the SS Square U Bolts have been given specialized finishes.

For example, SS 316 U Bolts would be used in applications that have a high demand for corrosion resistance to humidity and other corrosive media. Therefore, those bolts made from either 316 grade stainless steel or 304 SS U-Bolts or carbon steels are finished by hot-dipped galvanization, which is known to increase the general corrosion resistance for these alloys
