Patta self drilling screws are often identified by the bit shaped point of the screw and are designed for a range of applications like fastening metal to metal and metal to wood.

What are PATTA self drilling screws?

Self-drilling screws do not require a pilot hole, which accelerates installation time and lowers the value and want of additional drill bits. This extra functionality and value saving feature make self-drilling screws the clear choice for metal building construction.

The drill points are numbers #1 through #5 and also the amount of steel they will drill through increases because the numbered point increases.

Typically, self-drilling screws are utilized in light gauge applications, but a #5 drill point can drill through and fasten up 1/2″ of steel. During installation, self-drilling screws also will tap threads to a degree.

During a single time-saving operation, these screws drill, tap and fasten. Do not use self drilling screws in blind holes. The drill point must also drill entirely through the fabric before the primary thread begins to string into the fabric. That ensures proper fastening because the fabric is going to be fully engaged by threads.

Drill chips are created that affect electrical and mechanical equipment. Four different point styles—#2, #3, #4 and #5—are available. Generally speaking, a #2 point is employed with light gauge materials, #3 for medium gauge, and #4 and #5 points with heavy gauge materials.

Type U metallic drive screws have spaced spiral threads and a sharp point. These screws are forced into the fabric. Drive screws are considered permanent whereas other tapping screws will be easily removed.
