Features & Benefits

bigHead® fasteners are used extensively in many industries including plastics, auto, engineering, 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, designers and manufacturers can specify bigHeads® for "blind" application to almost any surface or material.

*These fasteners are supplied with self-adhesive masking dots.
