150mm long, Merlin Grey Molded Head, Carbon steel, sheet to timber self drilling screw with 19mm bonded washer. - Sold in Bags of 100no - (CODE: FD1FXWT15018B25)


To suit Merlin Grey (BS 18B25) box profile roofing and cladding sheets.  Colour coded molded nylon head eliminating the need for separate push on fixing caps.


Widely used when installing box profile steel sheets to timber supports.  Designed to be fixed through the valley (low part) of the box profile roofing or cladding sheets.  The self tapping screw will drill it's own hole through up to 0.7mm thick steel sheeting and then into wood.

The 19mm bonded galvanised washer gives a watertight fixing point through the valley and the course thread ensures the strongest possible fastening in to timber supports beneath.  (Fixing through the crown of the sheet should be avoided where possible as this can often cause the crown to dent if over tightened, it can also allow for more movement at the fixing point.)

  • 150mm long x 6.3mm diameter self tapping screw with course thread for firm hold into steel
  • Ideal for fixing 100mm or 115mm core insulated composite panel sheeting to timber supports
  • BI Hex Colour coded molded head so no need for separate colour caps.  Bi-Hex socket available here
  • Comes complete with 19mm diameter bonded galvanised washer.
