Color Painted Roofing Screw self drilling screw with EDPM Washer for Wall

1. Product Description

Hex Washer (Unslotted) Head Self Drilling Screws (Zinc-Plated Steel) are designed for use in metal applications. Self-Drilling Screws, also known as Tek screws, eliminate the need for a pre-drilled hole.

Like self tapping screws, self drilling screws cut threads while being installed. 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,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.
