A4 (1.4401  grade) austenitic stainless steel composite panel fastener.
A4 (1.4401  grade) austenitic stainless steel composite panel fasteners, dual threaded purpose designed self-drilling composite panel type, with 5.5 mm diameter threads into the purlin/ rail and an enlarged outer sheet support thread of 7 mm diameter immediately below a thread free section. The head is the industry standard 8 mm hex head.
The enlarged thread of 7 mm diameter provides support for the weather-sheet against concentrated loads. To prevent over-torqueing there is a thread free section behind the washer. These features combine with the sealing element below to achieve an airtight and water tight connection.
The sealing element comprises of a light grey EPDM of 3 mm thickness, soft minimum 60º shore hardness, to achieve air tight and water tight connection.
The EPDM sealing element is permanently bonded (vulcanized) to a 1 mm austenitic stainless steel conical shaped backing washer.
Up to 40 years (period to be confirmed and agreed specific to the project).
The SXC-A4 Fasteners are ETA approved (ETA number 13-183) and are CE marked. Technical performance in terms of tensile and shear are all documented in the ETA to enable the engineer to determine safe working loads in accordance with EuroNorms.
Fastener and washer manufactured from A4 (1.4401  grade) austenitic stainless steel and are therefore suitable for all corrosivity categories; C1–C5 as defined in BS EN 12944
