Standard bigHeads come in packs of 100.
If we have your part in stock, we can get it to you in 2-3 days. If it’s not in stock, the lead time is 7-10 days from receipt of your order.
There are 400 bigHeads in our standard range. You can see them all here.
Yes. Just contact us and we can build you a custom bigHead.
For customers outside the UK, please see our distributors listed by country.
Yes. We offer discounts on orders of six or more packs. And there are even better discounts if you order more than 11 packs. (Note, each pack contains 100 bigHeads).
Yes. Please contact us so we can learn more about your project and how we could help.
This will depend on many variables, such your design constraints and loading requirements. We can guide you toward the right solution from our 11 standard Heads or design something specific for your application.
As an initial guide we publish tensile load-to-failure values on our web site; however, as we have many options to tailor our technology to your specific requirements, can you tell me how strong you need it to be?
We can tailor products to your requirements if necessary, but we have already optimised our standard products to offer optimum performance at minimal unit weight. If none of our standard solutions are suitable we would be happy to offer a bespoke solution to meet your needs.
As a typical guide, nominally 1mm, but this is very much driven by the adhesive used and we would always recommend you discuss this with your nominated adhesive supplier to ascertain the optimum gap required for your application.
Before we consider any bespoke solution, please explain your requirements in more detail; armed with this information we can consider the optimum solution for your application.
We publish ‘Maximum Recommended Tightening Torque’ values on our web site as an initial guide, however, it is important to understand how any joint design/configuration can impact these values. bigHead are happy to offer further guidance in this area if/as necessary.
bigHead’s welding technology does permit some flexibility within these material families. To be able to offer any variant solution we would need to understand the full requirements of your application, including usage volumes, such that we can fully evaluate the technical possibilities & commercial viability of any such supply.
For male (M1 code) and female (F2 code) products, we recommend shutting-off on the stepped flange diameter at the root of the fixing component. bigHead products have been designed with this functionality in mind.
bigHead has already developed product variant solutions and associated tooling to support customer projects with this requirement and we would be pleased to discuss your needs in more detail.
Perforations within the Head offer a mechanical ‘rivet-type’ interlock between the fastener & adhesive, whereas a plain Head solutions offers a greater bonding area and more film thickness control. To define which solution is best we would need to understand how the fixing will interact with your substrate and any application constraints, including any need for automated installation.
The perforation pattern and Head-to-fixing ‘footprint’ has a direct correlation to the performance capability of any product combination. Combined with this, the performance values of an installed bigHead solution is very much dependent upon the strength and rigidity of the substrate into/onto which the fixing has been installed.
