bigHead-JackNut® combination solves composite panel fixing problem

One very recent development from bigHead is the bigHead-JackNut® fixing.

As with many requests we receive this fixing was developed to solve a specific problem, how to affix into a single skin of a composite foam-filled sandwich panel without the requirement for bonding.  The fixing also needed to be capable of spreading applied loads onto a very thin substrate (3mm thick), should permit installation into the finished composite panel with access from one side only and without the need for any specialised install criterion.

bigHeads' solution was to take an already successful fixing solution for thin, lightweight materials, the 'JackNut®' and marry this technology with that of a bigHead.  The result below clearly illustrates how bigHead's versatile, flexible manufacturing capabilities and approach to problem solving has many facets.  JackNut® is a registered trademark of Emhart Teknologies.

Combining bigHead technology with that of the JackNut® brings the following features to the end-user:

• Capable of being installed from one side of the panel
• Fastens into blind holes
• Fastens securely despite burrs or uneven substrate
• Hole size tolerant
• Provides large 'open-side' bearing area
• Provides large 'blindside' bearing area
• Will not distort or deform soft plastics or thin sheet
• Capable of accommodating a wide grip range
• Can be set with manual or pneumatic tool
• Available in Mild Steel + BZP only & in sizes M4, M5 & M6 Metric coarse thread form

bigHead solves corrosion problem with unique fixing solution

bigHead was recently approached by a leading specialist in phenolic resin-based syntactic foam insulation and fire protection systems to solve a problem that traditional fixings were not.  To provide a solution which removed the need to weld-on insulation retention pins required to hold the protection system in place.  Traditional methods of welding on the pins was leading to problematic corrosion issues particularly on offshore applications, resulting in a customer-driven need to find an improved fixing solution.

bigHead rose to the challenge, again proving how their manufacturing flexibilities and technical know-how approach to solving problems like this was well within their capabilities.

The solution: a 316 stainless steel bondable fixing that completely removes the need for welding and the implied cost and corrosion issues they bring; utilising bigHead's unique perforated head design to ensure high load-carrying characteristics and capable of being applied to many substrates with ease.

Following initial bonding of fixings to the downward-facing steel structure the bigHead 'Butterfly' design of the retainer-bracket can then be over-sprayed with a wet-plaster system, thus ensuring complete protection of the fixings from heat, fire and other environmental conditions.

All metal Lock-Nut version

Following requests from many of our clients we have been working on a new design of bigHead that can offer the facility of locking the fixing screw into a bigHead fastener. The result, as you can see below is the first of it's type and another addition to the ever expanding bigHead range. The part shown has been designed around our flagship head size (the B38 round), and utilises an all metal locking nut for added strength and security.
