The marine industry applications from bigHead follow many of the same characteristic requirements as other industries where composite materials are being increasingly used for structures, components and panels. bigHead offers efficiency and cost savings in manufactured parts and assemblies.
The invisible-to-the-eye fastening solution can be equally applied to highly secure panel to panel assembly or component to panel integration, helping boat builders reduce the expense and difficulty of vessel construction. Available as standard in 316 marine-grade stainless steel, the reliable and time saving fastener, is widely used and well proven in the marine sector - from powerboats to luxury yachts and from jet drive boats to RIBs and even surf boards.
Backed by a full and complete engineering service for custom designed bigHeads, designers can enjoy the freedom to create attractive and aesthetic lines and at the same time ensure manufacture and assembly times are minimised.
The marine industry in particular is challenged with maintaining maximum panel strength whilst minimising installation weight and size. In addition to the potential for exposure to the harsh environments endured by marine vessels, many applications also require fixings to be completely waterproof, favouring the selection of bigHeads which need no drilling and inherently provide a watertight fixing.
The fastening solution may be surface bonded to or embedded in materials that include carbon fibre and GRP composites as well as SMC and foam-core materials. A luxury yacht builder that requires flexibility for their engine room fit-outs uses surface bonded bigHeads to directly mount fuel line and coolant plumbing and other small equipment componentry to GRP wall panels.
Rather than drill holes and fix brackets, a simple one-step process allows fast installation of bigHeads with the ability to adapt the panel exactly as required with threaded male and female, or hook & clip type fasteners from the standard range.
bigHeads can also provide high strength fixings. A solar powered boat project uses 20 surface bonded bigHeads to enable the fast mounting and removal of an electric motor cage to the very thin carbon fibre floor panel. Using a structural adhesive, no drilling is required, removing any possibility of water ingress or material weakening.
bigHeads could be used for a manufacturer of water jet powered tenders for luxury yachts as a discrete mechanical fixing point on the exterior of the hull for the jet propulsion system. With the fasteners discretely embedded in the GRP material during the manufacturing process, secondary processes are eliminated, a waterproof solution is applied and a low vibration but highly secure structural mounting arrangement is ensured.
bigHeads are also used to provide fixing points for harnesses and other equipment on RIBs manufactured from soft PU or PVC materials. An M6 threaded 316 stainless steel bigHead is encapsulated into weld-able PU disc. This low profile assembly is then ultrasonically welded into the fabric layers of the RIB, maintaining a completely air and watertight seal whilst providing a high strength mechanical fixing.
This is an example of the engineer-to-engineer process that bigHead offers which takes a concept to solution approach and follows development, prototyping, thorough testing and customer approvals as a joint project.
Other examples for the marine industry include cabin panels, hatches, interior and exterior furnishings, deck and equipment fixings, insulation fixings, light clusters, wiring harness supports and more.
bigHeads are widely used across many other industries where composite products, components and panels require discrete fastening. In addition to marine & boatbuilding, applications range from specialist and luxury car production to building and construction, rolling stock, leisure vehicles, and many other general industries.
