Application

Roofing

Self-drilling screws for metal roofing are specially designed with a washer to form a tight seal when fastening. As with all self-drilling screws, they have a drill bit formed point that makes inserting them quick and easy.

Sheet Metal

Metal sheets are used to frame a wide variety of products. To speed up the production process and ensure tight connections, self-drilling screws are used as fasteners. The drill-like tip of self-drilling screws is preferred over other methods of fastening due to its efficiency. Industries that use self-drilling screws for metal fastening include automobile construction, building, and furniture manufacturing.

The design and construction of self-drilling screws allows them to pierce 20 to 14 gauge metals.

Framing

Self-drilling screws for framing must be able to cut through heavy duty metal studs. They have special heads designed to decrease driving torque but have exceptional holding strength. They are capable of driving through metals of up to 0.125 inches thick with an RPM rate of 1500. They come in a variety of metals to fit the operation and application.

Regardless of if the material to be drilled is metal lathe or heavy gauge metal (between 12 to 20 gauge), self-drilling screws can easily connect and frame a structure.

Drywall

The unique feature of drywall self-drilling screws is their countersink head that neatly fits into the drywall without tearing or damaging the paper and avoids head pops. They are generally coated for interior applications and come in numbers 6, 7, 8, and 10 diameters. They are flexible enough to be attached to wood or metal studs and include rolled threads for added strength and holding power.
