Coloured-head screws Cream stainless steel 4.8 x 50 mm - Box 100 Pieces

When you want to get started installing trespa panels, HPL panels or other facade panels, you have a number of options. Namely, you can choose to glue or screw these panels. The disadvantage of gluing is that the glue does not hold as firmly as screws in a strong storm. There is also a chance that the glue will dry up and crumble over time. For this reason, Coloured-head screws have been invented. As the name suggests, you can recognise them by the wide colourful head that comes in a variety of colours. The advantage of these Trespa screws is that they have a very wide head, giving them a very high clamping range. The tension is distributed across the entire width of the head.

This ensures that your Trespa, HPL or other facade panels are firmly fixed.

Trespa screws are available in many types and sizes. At Wovar you will find a wide range of Coloured-head screws in different lengths and colours. Think of the popular colours White, Black, Grey, Anthracite, Beige and Cream White. To protect these colours, the head has a so-called Qualicoat coating. This high-quality coating protects the screw head from UV rays and scratches and also ensures that the deep colour is retained.

Wovar offers the HPL screws in various lengths, including the much-used 25 and 38 mm versions. The screws possess a wide head with a diameter of about 12 mm. This ensures that pressure is distributed over a large surface area and the screw has a high clamping range. With the included Torx-20 bits, you can effortlessly screw the trimming screws into the wood. Wovar's Coloured-head screws consist of A4 stainless steel. The big advantage of this type of steel, compared to the A2 variant, is that it is suitable for coastal areas.

Using HPL screws when installing

When installing facade panels you should always pre-drill the panel. You do this with a carbide HSS drill bit, which you can find in our range of hardwood drill bits. We recommend pre-drilling the central hole (also called the fixation point) with the 5 mm variant. This drill is just wide enough for our Coloured-head screws. You drill the fixation point centrally at each beam to which the board will be Securing, regardless of whether you are using 2, 3 or more beams. You then pre-drill the other holes (with which you secure the panel to the beam) with an 8-mm hardwood drill bit. This ensures that the panels can 'work'. By 'work' is meant the expansion and shrinking of the panel as a result of temperature changes. You drill these holes every 40 cm. Keep in mind when drilling that these holes must be at most 10x the panel thickness (in mm) from the panel edge for optimal fastening.

After drilling, it is important to find the right screw for your job. Look carefully at the RAL colour of your wall cladding panel beforehand. This way, you avoid having the wall plate a different colour to the head colour of the screws. Once you have found the right colour, choose the right length. The right screw length also depends on the cladding panel thickness. Below are shown in a small diagram the most common screw lengths and the corresponding panel thicknesses.

Now you can start installing the boards. It is best to start by installing the plate at the drilled fixation points. This has the advantage that the plate can easily be 'shifted' if the other drill holes are not perfectly aligned with those of the plate. Then tighten it. Be careful not to tighten it too much, just 'hand-tight' is tight enough (as the plate will expand and shrink). Then start tightening the other screws, until all screws are in and the plate is firmly in place. Note, here again, that 'hand-tight' is sufficient in view of the working of the plate.
