Our Colour Coded Cover Caps have been designed and moulded to fit perfectly over our 5/16” / 8mm hex head fixing screws using a 19mm inner diameter.
Available in an extensive range of colours to provide an almost perfect match to your chosen colour of roofing sheets. Please be aware that these caps are plastic and will vary slightly against any steel product.
We also offer a 29mm inner diameter Poppy Red Cap with a 29mm washer for sealing your roof lights when fixing through the trough to add extra cover. The 19mm inner diameter Poppy Red Cap is to be used with your stitching screw. Clear Caps are also available for use with Galvanised Finishes and Rooflights also.
If your project is situated in an exposed / windy area please apply a touch of silicone inside the cap before fitting to the fixing head to prevent them blowing off.
