bigHead® Embedding and Surface Bonding Fasteners

The principle of a bigHead® fastener is simple: a fixing like a threaded collar, stud, nut or pin is welded to a perforated head. 

bigHead® Embedding and Surface Bonding Fasteners

The unique bigHead® design enables a plastic or composite component to be fastened securely with no holes, no punching or drilling. The bigHead® can be installed after the manufacture of the parent component, “post-process”, or during the manufacture, “co-process”.

bigHeads® are an ideal way to create a secure fixing point on a component. The fixing point enables the component to be efficiently fastened within an assembly or combined with secondary fastening elements. Examples:

1. Threaded fixings for use with nuts or bolts to fasten components

2. Cable tyrap for looping cable-ties in place
