What is a Light Section Drillscrew?
A light section drillscrew is designed to drill a sheet into a cold rolled steel section (for example a Zed Purlin), up to 3mm thick.

What is a moulded head?
Unlike other tec screws, this fixing has a Plastic moulded Head which will match the colour of your roof or cladding sheet, whilst being aesthetically pleasing, this also protects the head of the screw and increases the life expectancy.

What material are they made of?
These Screws are made of galvanised steel.

What are these used for?
This longer length is typically used with Insulated Panels or built up systems, see the product description for a sizing chart.

Where are these screws fixed?
These screws are fixed into valley (trough) of a box profile.

Do I need anything else?
If you haven’t fitted these before, you will most likely need to purchase and 11mm Bi Hex socket to fix them with, we also supply this.
