Screw Fastening

Screw fastening systems are commonly used for the attachment to cold-formed steel members. Self-drilling screws allow for direct attachment without the need for additional equipment such as a drill bit or welding machine making screw fastening portable, fast and lightweight.

When selecting the right screw for your application, you must evaluate the following:
