Wings screw, Tek screw, is
specialized fasteners commonly used in construction and metalworking to fasten
metal to metal or wood to metal. These screws have a unique drill bit-like wings
that allows them to drill their own pilot hole as they are driven into the
material without pre-drilling. This makes them ideal for tasks such as
attaching metal roofing panels, steel framing, or sheet metal to wooden studs.
Tek screws for steel are also commonly used in HVAC systems, automotive assembly,
and various industrial applications.
