Features & Benefits

Standard bigHead Threaded Bolts are extensively used in plastics, automotive and engineering industries, and increasingly in construction, building and other fields. They can be molded-in during manufacture, riveted, screwed or spot-welded. With the advent of modern adhesives providing permanent bonding to almost any surface, designers and manufacturers are now able to specify bigHead Bolts for "blind" application to almost any surface or material.
