How do I choose the right fastener for my application?
The right fastener depends on what you are fastening, what you are fastening into, and the conditions the solution needs to handle over time.
At Unite Fasteners, product selection starts with the basics: the application, the substrate and any additional fastening requirements. From there, it is important to consider the corrosion class, drilling capacity, clamp length, installation speed, colour matching and the correct bits or sockets for safe installation. Choosing correctly from the start helps create a fastening solution that is safe, reliable and cost-effective over time.

The Unite material explains that choosing the right corrosion class is an important part of product selection, and that stainless fasteners can often be the more economical choice over time. Marutex is described as a self-drilling stainless screw in heat-treated special steel, with strong drilling performance and a long service life in exposed environments.

Can Unite Fasteners help with standing seam roofing applications?
Yes. Through Bjarnes System, Unite Fasteners can support standing seam roofing with clip systems, fastening products and technical guidance.
The Bjarnes handbook makes it clear that standing seam roofing requires more than simply choosing a clip. The correct solution depends on factors such as local conditions, wind load, snow load, roof geometry, substrate and fastening plan. The handbook also explains that Bjarnes System helps customers with these questions so they can feel confident in the selected solution and work with one contact for their clip needs.
Visit Bjarnes System or contact us for project-specific guidance.
Do you offer both standard products and project-specific solutions?
Yes. Unite Fasteners offers a broad standard range, but we also support project-specific and customer-specific solutions when needed.
The Unite catalogue highlights one of the market’s broadest and most complete fastening ranges, but it also states that new solutions, including customer-unique ones, are part of the company’s way of working. It even explains that when the exact screw or rivet needed for a project does not exist in the normal range, that is not necessarily a problem. This is a major strength for customers who need a solution that matches a specific project rather than a generic shelf product.
