What sizes does the screw with rubber sealing for the thermal panel come in?
Shopify offers four specifications: 5.5/6.3 x 100, 120, 150, and 175 mm. Each size is available in RAL 9002, RAL 3009, and RAL 7016, totaling 12 variants. The public listing does not explain which two parts correspond to 5.5 and 6.3 mm, so the screw design is verified by the technical drawing rather than assumed from the short name.
How is the length 100, 120, 150, or 175 mm chosen for a thermal panel screw?
The length is determined by the panel thickness, rib height and cap, the type of supporting base, and the required penetration into it. There is no reliable rule of "panel thickness plus fixed allowance" without data for the specific system. Before ordering, the installer must specify the fastening layer and check the minimum anchoring in the screw’s technical sheet.
What is the role of the rubber sealing on the thermal panel screw?
The sealing is part of the waterproofing detail around the fastener but does not compensate for an incorrect screw, incompatible cap, or deformed rib. It should press evenly without overtightening. Tesla Panels explicitly warns that screws must be tightened optimally to avoid panel deformation. The material and size of the sealing are not published on Shopify and must be confirmed.
Should this screw be used with a cap on a roofing panel?
For Tesla roofing panels, the official instruction requires the self-drilling screw to pass through the ribbed area with a cap. This does not prove that every size of this Shopify product fits every cap or TUR panel. The profile, hole, washer, and length are coordinated as a set. For another manufacturer, follow their exact installation detail, not Tesla’s instructions.
How do I choose the color of the screw for a roofing thermal panel?
Available colors are RAL 9002, RAL 3009, and RAL 7016. Choose the visible head color according to the exterior sheet metal, but first confirm the mechanical size and length. The same RAL does not guarantee the same gloss or finish, and Shopify does not specify the screw’s finish. For sensitive visual results, compare a physical sample with the specific batch of panels.
Is the screw suitable for a wall panel with hidden mounting?
This cannot be confirmed from the title alone. The hidden wall joint has its own geometry, fastening zone, and requirements for the head and load capacity of the fastener. This product is generally described for thermal panels, without a technical sheet or distinction between roofing/wall. Use it in a hidden joint only if the panel manufacturer specifies it and the size is calculated for the support.
