Screws
The fastening of Steel Framing components (Termosteel studs and tracks) is made with screws that vary in size according to the cladding materials to be used.
The cold-formed steel must not be welded to fasten pieces because the protection provided by the zinc coating following galvanization might wear out. Considering this, we advise using electrolytic zinc-coated self-drilling screws because of their anti-corrosion properties. These screws are manufactured with boron micro-alloyed steel and treated with organic compounds.
Unlike Drywall screws, Steel Framing screws are self-drilling fasteners with drill tips that guarantee steel drilling and fastening in one single operation, making the structure assembly easier.
Screws vary in size and diameter according to use. The T1 screws or lentil head screws (8×1/2” or 9/19” and 10×3/4”) prevent steel breaking, and the hexagonal screws serve as panel fasteners and steel frame stiffeners. Based on the structural design proposal, screws come in the following different dimensions: 10×34”, 12×3/4”, 14×1”, and 14×11/2”.
GENERAL CONSIDERATIONS
1.- Screw dimensions to ensure proper fastening.
2.- Spacing.
3.- Steel thickness (self-load bearing capacity).
4.- Type of handling, drilling, and re-drilling.
