1. Product Description

Self-Drilling Screws, also known as Tek screws, eliminate the need for a pre-drilled hole.Similar to a sheet metal screw, but it has a drill-shaped point to cut through the substrate to eliminate the need for drilling a pilot hole. Designed for use in soft steel or other metals. The points are numbered from 1 through 5, the larger the number, the thicker metal it can go through without a pilot hole. A 5-point can drill a 0.5 in (12.7 mm) of steel, for example.he length of the drill point determines the material thickness which the screw can reliably penetrate.When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined.

Self-drilling screws have hardened drill points that will drill and thread in structural steel, mild steel, aluminum and wood. Hex Washer (Unslotted) Head Self Drilling Screws (Zinc-Plated Steel) are designed for use in metal applications.A self drilling screw, however, has a notched point that acts as a drill point and therefore does not require a pre-drilled hole before installing. The generic name for these screws are Self Drilling,These drill points are manufactured in the same method as the high speed drill bits. Self-drilling screws are available in a variety of finishes with unique product features to suit a wide range of environmental conditions.

4. Advantages

1· High-hardness points and lead threads for drilling and tapping

2· Lower-hardness in load-bearing threads for ductility

3· Virtually immune to delayed embrittlement failures

4.· Stalgard coating provides 800 hours of salt spray resistance (per ASTM B117)
