Details

Application Areas:

Carpenters/ roofers/ (prefabricated) timber construction companies

For fastening non-approval-relevant timber constructions

Also suitable for fastening non-approval-relevant metal-based attachments (such as joist hangers)

Usable directly in wooden substructures or with different types of plastic dowels in masonry or concrete

Installation indoors or in dry areas of wet rooms

Outdoors without direct weathering

Advantages:

  • Versatile application areas
    • Possibility to use in different anchorage grounds
  • Easy and firm tightening
    • Hexagon head (also re-tightening)
  • Stable and durable timber structures
    • Full thread (higher load capacity)
  • Process safety
    • Standardized quality by norm DIN 571 (geometry tolerances and mechanical properties)

Processing information

Pre-drilling: metal plates = thread-Ø (max. + 1 mm) / wood = max. screw core-Ø
Using with dowels: dowel size should be 2 mm larger than screw thread-Ø
Important: if fastening is intended in safety-relevant areas, screws with approval (ETA) or with a harmonized standard according to CPR (Construction Products Regulation) must be used

Advice

Additionally usable: DIN 440 washers for increase of stability and head-pull through loads
