SCREWS FOR FAÇADES FAS A4 | AISI316
Cladding screws: when installing external wall cladding, A4 | AISI316 austenitic stainless steel is a must in all conditions.
FAS A4 | AISI316 screws for panels for exterior façades are specifically designed for installing external wall cladding onto timber substructures.
Thanks to the flange head, partially threaded shank and self-tapping tip, they are the ideal solution for façade panels such as HPL, fibre cement boards, and vertical and horizontal metal finishes.
A4 | AISI316 austenitic stainless steel guarantees excellent corrosion resistance even in the most aggressive environments, making these façade fasteners suitable for external wall cladding in corrosion class C5 and for use on aggressive T5-class timber. Available in white, grey and black, these cladding screws ensure colour uniformity with the installed panels, with the option to customise the head colour on request.
Suitable for outdoor use in aggressive environments without the need for pre-drilling, these screws for façades ensure fast installation and long-term reliability, and are compatible with the most widely used fibre cement, HPL and metal finishes.
FAS A4 AISI316: stainless steel façade fasteners.
FAS A4 | AISI316 screws for façade panels are manufactured from austenitic stainless steel, offering superior corrosion resistance compared to traditional carbon steels.
The self-tapping screw tip combined with the partially threaded shank allows direct fastening without pre-drilling, reducing assembly time on site.
The flange head distributes the load evenly across the panel surface, ensuring optimal mechanical hold and reducing the risk of cracking in fragile materials such as fibre cement and HPL boards.
A4 | AISI316 stainless steel ensures corrosion protection in all environmental conditions, including high-salinity marine environments classified C5, and maintains structural integrity even on high-tannin timber, class T5.
These external wall insulation screws can also be installed without pre-drilling on steel or aluminium sheets up to 0.5 mm thick, ensuring versatile application for panels for exterior façades in different materials and construction systems.
The availability of multiple colours allows customisation of the screw's appearance, in harmony with the architectural design.
How to choose the right screws for external wall cladding according to materials and thickness
FAS A4 | AISI316 is the correct choice for panels for exterior façades, thanks to the stainless steel construction that guarantees corrosion protection in aggressive environments (C5) and on difficult timber (T5). The self-tapping screw tip allows direct fastening without pre-drilling on substrates up to 0.5 mm thick, and is compatible with HPL, fibre cement and metal finishes.
A4 (AISI316) austenitic stainless steel contains molybdenum, which significantly improves resistance to localised corrosion compared to traditional steels, particularly important in marine or high-humidity environments.
