APPLICATION

This specification covers two types (Type A and Type B) of high strength U-Bolts used to fasten springs, fifth wheels, tow loops, and similar parts, where higher clamp load capacity is required. Both types of U-Bolts can be provided as either quenched and tempered (Q&T) products or as cold-drawn and stress-relieved (CDSR) products. The new Type B U-Bolt exhibits higher strength properties.
