Clearfix Self Cutting Polycarbonate Screw & Dome Seal
Size: M6.5 - 14 x 50mm
On a cloudy and sunny day, Polycarbonate roofing experiences a process called “expansion and contraction”. This can give that “cracking” and “creaking” sound, which is caused when the roofing panels rub against the timber batten the panels are fixed to.
To reduce and avoid this noise, we recommend the use of “self cutting” screws. These roofing screws incorporate a “cutting head” on the shaft which cuts an oversized hole in the sheet, allowing room to expand, thus hugely reducing that annoying “cracking” sound.
Predrills and self centres during installation.
Unique wing design cuts its own thermal expansion hole.
Modified drill point allows application into both timber and steel.
Save 50% on installation time.
**Allow approximately 6 screws per lineal metre.**
