SL2 Stainless Steel Clamping Fastener

Application

Clamping of laps in roof and wall cladding systems e.g. composite/ built up.

Description

A4 (1.4401 [316] grade) austenitic stainless steel clamping fasteners, with 5.5 mm or 6.3 mm diameter threads. The head form comes available in the industry standard 8 mm hex head or Irius® low prolfie.


Features and benefits:

  • Under the head is a free spin zone, which enables the components to be clamped tightly together to prevent over torqueing and to compress the sealant when applicable. These features combine with the sealing element below to achieve an airtight and water tight connection.
  • The clamping fastener has a spin free zone under the head to gather all the sheet material and compress between the soft EPDM washer and cut thread end to create a seal. The spin free zone ensures over-driving cannot occur and damage the connection.


Sealing element:

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.


Approvals:

The SL2-S-A4 Fasteners are ETA approved (ETA number 10-0198) 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.
