Timber construction screw EASYfast
Art.No. 128883

separate multiple mail address using a comma.

* mandatory fields

Details

Application Areas:

Carpenters/ roofers/ (prefabricated) timber construction companies

Applicable for load-bearing and (non)approval-relevant timber structures

Wood joints in structural (prefabricated) timber constructions: on-roof insulations, timber (frame) constructions, formworks, rafter and shifter attachments

Installation indoors or in dry areas of wet rooms

Outdoors without direct weathering

Advantages:

  • High load-bearing capacity
    • Washer head ensures higher load values than comparable standard countersunk head screws
    • Extended thread length and strong thread flanks ensure optimum wedging in wooden substrates
  • Efficient screwings
    • Higher load-bearing capacity of washer head, therefore less screws and screwing time required
  • Power and energy saving
    • Reduced screwing torque due to milling ribs at shaft and special sliding coating on the thread
  • Reduced wood-cracking
    • Notch (“CUT”) at screw tip for close-to-the-edge screwings
  • Maximum safety and high product quality
    • Ensured by ETA-12/0280 and external independent testing institute

Processing information

Load-bearing, approval-relevant timber constructions always have to be calculated by structural engineer with ETA of applied screws
Design of fastening points/ overall construction must be based on the characteristic load values of screw type and installation specifications within ETA-12/0280
Fixing of thermal insulation must also comply with local applicable national regulations
Only countersunk head screws allowed for connecting wood-based materials to roof-mounted insulation systems (ETA-12/0280: A.1.4. installation provisions)

Advice

Applicable with or without pre-drilling (pre-drilling-Ø ≤ screw core-Ø)
Pre-drilling usually not necessary for screwing into softwoods (e.g. spruce, pine, fir)
When using hardwood, pre-drilling is recommended to prevent screw breaks
When using metal attachments (screw-head-side), pre-drilled hole in the metal part must be larger than thread-outer-Ø

Productadvisor for Houtschroeven

Verschillende toepassingsgebieden vereisen verschillende schroef- en draageigenschappen van een schroef. Opmerking: Voorboren wordt met name aanbevolen voor schroeven die zeer dicht bij de rand komen of om het risico op splijten te verminderen.
