Narrow Your Results By

Self-drilling screws combine a drill point with a thread-forming tip to penetrate and fasten metal surfaces in a single operation, eliminating the need to pre-drill pilot holes and dramatically reducing installation time in metal framing, steel roofing, and light steel fabrication. Also known as Tek screws, self-drilling screws are available from Blue Ribbon Fastener in hex washer head, pan head, and flat head styles with zinc and ceramic-coated finishes for indoor and outdoor applications.

Usages for Self-Drilling Screws

Self-drilling screws are used wherever a fastener must drill through and thread into light-to-medium gauge steel without a pre-drilled hole. Common applications include metal stud framing to track, metal roofing and wall panel attachment, HVAC ductwork assembly, steel purlin and girt connections, light steel fabrication and assembly, and metal building system erection. The drill point number (1 through 5) indicates the maximum steel thickness the screw can penetrate — selecting the correct point is critical to achieving reliable drill-through without break-out or stripping.
