Screws: Know the Difference Between SELF-TAPPING SCREW and SELF-DRILLING SCREW
What is the difference between a SELF-TAPPING SCREW and a SELF-DRILLING SCREW?
a) SELF-TAPPING SCREWs create threads as they are driven into a pre-drilled hole, while SELF-DRILLING SCREWs have a drill-like point that creates a hole as they are driven.
b) SELF-TAPPING SCREWs are used exclusively in metal applications, while SELF-DRILLING SCREWs are used in wood.
c) SELF-TAPPING SCREWs are larger than SELF-DRILLING SCREWs.
d) SELF-TAPPING SCREWs and SELF-DRILLING SCREWs are two different names for the same type of screw.
Final answer: SELF-TAPPING SCREWs create threads in a pre-drilled hole, while SELF-DRILLING SCREWs have a drill-like point that creates a hole as they are driven in. Both types can be used in various materials and their sizes are determined by the project's requirements.
Answer:
The primary difference between a SELF-TAPPING SCREW and a SELF-DRILLING SCREW is in how they are used to fasten materials.
A SELF-TAPPING SCREW creates threads as it is driven into a pre-drilled hole, which means you need to drill a hole first before it is applied. On the other hand, a SELF-DRILLING SCREW functions slightly differently as it features a drill-like point at its tip which allows it to drill its own hole as it's driven in.
It's important to note that it's not accurate to say that SELF-TAPPING SCREWs are used exclusively in metal applications, and SELF-DRILLING SCREWs are used exclusively in wood. Both types of screws can be used in various materials depending on the specific application.
Additionally, the size of the screws is determined by the requirements of the project and is not a distinction between these two types of screws.
