Coloured-head screws Black stainless steel A4 4.8 x 60 mm - Box 100 Pieces

When you want to get started installing various facade panels, such as the widely known Trespa panels, HPL panels or perhaps facade panels, you have 2 choices. Namely, you can choose to glue these panels, which has the disadvantage that in case of a strong storm or under humid conditions, the panels will come loose. There is also a chance that the glue will dry up and crumble over time. For this reason, Trespa 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 Coloured-head screws is that they have a very wide head, giving them a very high clamping range (after all, the tension is distributed over the entire head). As a result, your Trespa, HPL or other facade cladding panels will be securely fastened.

Trespa screws from Wovar

Our range HPL screws come in various lengths and colours. The response screws are available in the colours Black, White, Anthracite black, Beige, Grey and Cream. Thanks to the Qualicoat coating, the colours are deep and this coating is scratch-resistant and UV-resistant. Even many years after installing, the screws look like new. The available lengths are: 25 mm, 32 mm, 38 mm, 50 mm and 60 mm. The width of the head is 12 mm, giving it a very high clamping range. The thickness of the thread is 4.8 mm. The head is fitted with a Torx-20 drive, making it effortless to screw into the facade panels with the bit provided. These screws are made of A4 stainless steel. This has the advantage, compared to A2 stainless steel, that they are even more resistant to moisture, acids, salts and chlorine. This allows you to use these screws with confidence even when you live close to the coast.

Installing Trespa panels easily

When installing Trespa and other 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. Then pre-drill the other holes (with which you secure the panel to the beam) with an 8 mm hardwood drill bit. This allows the panels to 'work'. This is the expansion and shrinking of the panel due to temperature changes. You drill these holes every 40 cm. When drilling, keep in mind that these holes should be a maximum of 10x the panel thickness (in mm) from the edge of the panel for optimal fastening. Then determine the desired screw length, which depends on the panel thickness. Below is a brief overview of the various (standard) plate thicknesses and the suitable screws:

Now you can start installing the boards. We recommend you start by installing the plate at the fixing 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. Please note, here again, that 'hand-tight' is sufficient given the effect of the board.

Is this HPL screw not quite what you are looking for? Then take a look at our entire range of Coloured-head screws, where we have various other sizes and colours at our disposal. If you want to secure a rockpanel panel we recommend our rockpanel screws, these are supplied in the same Quality (A4 with Qualicoat coating). However, these are specially manufactured to always have the right clamping force for these specific boards for optimal results. For wooden cladding, on the other hand, we recommend our cladding screws. Thanks to the lens head, these screws provide an almost invisible fastening.
