Specifications
What is a drill screw?
A self-drilling screw is a type of screw that has similar design features with a drill bit with a tip that enables it to drill its own
hole. As the name implies, self-drilling screws do not require a pilot hole in order to perform as a fastener.
 
 
 

 

How are self drilling screws measured?

They are measured from the top of the head to the tip. Hex and hex washer head screws and bolts, although flat on the top and the bottom, are measured from the bottom of the head. From that point to the tip is the length of the screw. Self drilling screws are measured all the way to the end of the drill point tip.

 What does a self-drilling screw do?
Typically made from stainless steel, self-drilling screws are characterised by their drill-shaped point. This point enables the screws to drill into materials without the need for pre-drilled pilot holes, resulting in a more efficient fastening process.


Application

What are self drilling screws used for?

Self drilling screws have a point that acts as a drill bit and sharp cutting threads that tap the hole during installation. Self drilling screws are a commonly used variety of screw for quick drilling into both metal and wood. A self drilling screw can typically be identified by its point and flute (notch) tip.
