Timber To Steel

Timber To Steel Self Drilling FastenersRange of self drilling fasteners for fixing timber and other similar materials to steel. Manufactured from low carbon cold forming steel and case hardened, with a minimum 8 micron coating. Wings positioned just after the drill point ream a clearance hole through the timber, preventing thread engagement. These wings break off when they come into contact with the steel.

Heads are countersunk and ribbed for easier self embedding.

Where thicker timbers need be fixed timber can be countersunk.

Where steel is thinner then 1.5mm or Tactray systems see batten to deck range.

Above 6.0mm steel, limiting factor is tensile strength of fastener.

Pullover
This is normally the limiting factor and is dependent on the material being fixed.

Note: All figures are average test results and are ultimate failure loads; No safety factor has been used.

Batten To Steel Deck

Range of fasteners for fixing timber battens to steel sheetsRange of fasteners for fixing timber battens to steel sheets including applications such as "TacTray90" or "Trustray" systems.

Fasteners have a ribbed countersunk head above a self drill point complete with reaming wings, which have been designed to break off in steel sheet as thin as 0.7mm. These wings prevent thread engagement thus eliminating "jacking" of the timber.

Material Specification
High quality case hardened carbon steel to Din 7504

Coating
Carbon steel electroplated with zinc clear dichromate passivation for a corrosion resistant finish.

For thicker timbers or when fixing to aluminium sheet please contact sales.

Please note all figures are ultimate failure loads and no safety factor has been used. Figures are based on results obtained from tests carried out in accordance with equipment conforming to BS5427 on a random sample of fasteners.

It is recommended that unusual, critical, or demanding applications be tested individually.
