BigHead® Collars consist of an internally threaded collar welded to a large perforated head. Standard collar lengths range from 5-22 mm, and standard heads range in size from 19-58 mm across. They are available in several different standard head shapes, to suit your specific application needs, with or without a sighted center hole and customized shapes and sizes are readily available. Their large perforated "head" provides an invisible, molded-in fastener, fixed for life, with very high torque and shear resistance. These fasteners are made from mild steel or stainless steel.

                                                                        N/A BigHead® fasteners are used extensively in plastics, automotive and engineering industries, and increasingly in construction, building and other fields. They can be molded-in during manufacture, or riveted, screwed or spot-welded. 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. |
