Features and Benefits	N/A BigHead® fasteners are used extensively in plastics, automotive and engineering industries, and increasingly in construction, building and other fields.

With the advent of modern adhesives providing permanent bonding, designers and manufacturers are now able to specify BigHead® for "blind" application to almost any surface or material.
