Below is a list of Stud Bolts manufacturers from Albuquerque, New Mexico. A stud bolt is a mechanical un-headed fastener with a fully or partially threaded body that, with additional hardware, can secure two adjacent objects or surfaces. Unlike many types of bolts, this particular style is not driven into an object or surface, but passed completely through. Nuts or flanges on either end of the bolt then hold the two objects firmly together.
