Application

Secret fix installation of fibre cement cladding panels.

suitable for installation of a metal hanger onto cladding panels.

Description

The TUF-S rivets have a 6.0 mm diameter body made from grade A4 (316) austenitic stainless steel and a 3.3 mm mandrel manufactured from carbon steel.


It is important to note that the carbon steel mandrel is fully removed when installed.


Installation:

The TUF-S Rivets are used on secret fix rainscreen systems and are installed at the back of fibre cement façade panels.


  • Firstly a pilot hole is drilled into the back of the façade panel using a 6.0 mm stop drill bit.
  • The pre-drilled bracket is then positioned over the hole, the TUF-S rivet is pushed through the bracket into the hole and the mandrel is completely removed using a riveting tool.
  • Installation using the TUF-S rivet can be performed quickly and securely by one person, without using special tooling.
  • Installation time can also be reduced by up to 50% compared with conventional blind attachments.
  • This product can also be removed once installed if required.


This fastening solution cannot be overdriven during installation, due to its radial expansion. When the mandrel is removed, the partially cut thread becomes wedged into the back of the façade panel material, generating high pull out values. Spontaneous slackening due to expansion or vibration is impossible and due to the mandrel being fully removed a hollow point is left enabling any possible moisture to escape removing risk of delamination or deformation at the front of the façade panel.


Features and benefits:

  • Secured against unwinding.
  • Time saving installation compared to conventional blind attachments.
  • Simple standard blind hole sufficient - no complex undercut hole required.
  • Quick and easy installation with battery rivet gun.
  • Blind holes can even be drilled on site.
  • Removable possible via hex head.


Approvals:

With all leading fibre cement façade panel manufacturers.


It is also ETA approved (ETA number 15/0784) and 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.
