Unite Unifix mounting screws
Unifix mounting screws for timber and thin steel sections
Choose the right Unifix mounting screw
Our Unifix mounting screws are designed for fast, practical fixing work where the main job is fastening into timber or thin steel sections. The key decision is usually simple but important: choose the right point type for the substrate, then match the screw to the corrosion requirement and the visible finish.
Within the range, we offer sharp point screws for timber and selected light steel details, drill point screws for thin steel profiles, and stainless sharp point versions where a more corrosion-resistant choice is needed. Selected versions are also available with an extra thin head, and both sharp-point and drill-point variants can be supplied with painted heads.
What is included in our Unifix mounting screw range
Sharp point mounting screws
Choose our sharp point Unifix mounting screws when you need a straightforward fixing for timber or selected light steel details where a full drill-point solution is not the better fit. This is the practical starting point for everyday mounting work, and parts of the range are also available for outdoor use and with an extra thin head.
See sizes and details for our sharp point mounting screws on page 85 in the catalogue.
Stainless sharp point mounting screws
Use our stainless sharp point Unifix screws when you are fastening into timber and need a more corrosion-resistant option. They are the better choice when plain carbon steel is not enough, while keeping the same simple mounting logic as the standard sharp-point part of the range.
See sizes and details for our stainless sharp point mounting screws on page 85 in the catalogue.
Drill point mounting screws
Choose our drill point Unifix mounting screws when the main job is fastening into thin steel sections. They differ from the sharp-point range by being intended for light steel profile work, which helps you avoid using the wrong point type on steel-based installations.

Detailed Unifix mounting screw data in our catalogue
Below, you can compare the main Unifix variants in one place: sharp point, stainless sharp point and drill point mounting screws. This is the best place to check the length spread, visible outdoor-marked options, and where a stainless or extra-thin-head alternative fits the job better.
If your choice depends on substrate limit or exposure class, it is also worth reviewing our drilling capacity guide and corrosion classes guide before ordering.
Need help choosing the right Unifix mounting screw?
We help contractors, installers and purchasers match the right Unifix mounting screw to the real job — whether that means timber or thin steel, sharp point or drill point, a more corrosion-resistant choice, or a painted head that works better visually. If you send us the substrate, build-up and installation environment, we can narrow the range quickly.
How do I choose between sharp point and drill point Unifix mounting screws?
Choose sharp point when the job is mainly fastening into timber, or where the detail does not call for a dedicated drill-point steel solution. Choose drill point when the main substrate is a thin steel section. The deciding factor is the substrate and whether you need the screw to drill its way through the steel profile rather than bite into timber.
Are Unifix mounting screws suitable for timber, thin steel, or both?
The family covers both, but not every variant does the same job. Sharp point screws cover timber and selected thin steel details, stainless sharp point versions are aimed at timber applications, and drill point variants are for thin steel sections. That is why the first selection step should always be the substrate.
When is the stainless sharp point version the better choice?
The stainless sharp point version is the better choice when you are fastening into timber and need a more corrosion-resistant fixing. It is especially relevant when the environment, specification or service-life expectation pushes the job beyond a basic indoor mounting screw choice.
Why would I choose an extra thin head or painted head?
Choose these options when the visible result matters as much as the fixing itself. An extra thin head can help reduce how prominent the head appears, while a painted head helps the screw sit more discreetly against the surrounding surface. Where colour matching matters, our colour selection guide is the right next step.
What should I check before choosing the length or version?
Start with the full build-up and the substrate, then check the point type, corrosion requirement and finish. For thin steel work, make sure the chosen screw fits the profile thickness and intended drilling job. For exposed applications, decide early whether you need an outdoor-marked or stainless option rather than choosing only by length.
Can Unite help us choose the right Unifix mounting screw for our application?
Yes. If you tell us what you are fastening, what the substrate is, whether the job is indoor or exposed, and whether appearance matters, we can usually narrow the Unifix range down quickly and point you to the most suitable option.
