Vortex Stud screws have an ultra flat head for fastening thin metal studs where a very low profile head is required. 

Vortex Screws are a universal screw for fixing to timber and steel up to 1.5mm thick. Vortex framing screws are high performance, specifically developed for application in pre engineered building systems.

The Zinc Yellow corrosion protection system meets the requirements of ISO 9223 Category 2 (Internal application for mild environments).

AS 3566.2 (Self drilling screws for the building & construction industries) specifies the corrosion protection systems required on screw fasteners Classes 1, 2, 3 & 4 where Class 1 is intended for indoor application and Class 4 for environments up to and including ISO 9223 Category 4 (Severe industrial and severe marine environments).
