These are particularly useful when working with materials with a very short pot life such as gypsum, and which set hard in a few minutes. In these instances, it would be difficult to locate several separate bigHead® Nuts/Collars accurately in the short time available.

bigHead fasteners are load-distributing anchorages, designed originally for plastics users but now used widely throughout industry in metal fabrication and assembly. They provide a complete and versatile fastening system for such specialized molding techniques as rotational, injection, GRP and many others.

These can be supplied with male, female, threaded or unthreaded components in virtually any combination to suit your specific needs. They are available in male or female, threaded and unthreaded forms, with nuts, collars, studs and more (nuts and collars shown here). They are made in bondable steel or 316S11 stainless steel versions. The holes are 5mm in diameter, located at 20mm centers, and alternate across a center line to which your desired fastening components are jigged and welded at set centers.
