Is A Sheet Metal Screw The Same As A Self-tapping Screw?
A self-tapping screw can be defined as a tapping screw. It is referred to as a sheet metal screw as they are heavily used in the sheet metal trade. Whatever name it is the device is designated to contain a form of mating threads.
What Is The Difference Between Self-tapping And Self Drilling Screws?
Self-tapping screws are designed having a capability to tap threads into the material. These screws cannot be employed to go through metal without having a pre-punched hole. A self drilling screw has a drill bit-shaped point in front of the metal. These screws are designed to create their own pilot hole to affix the material. Both these screws are used interchangeable, and mixing them up can cause failures in the field.
How Do You Turn A Bolt Into Self-tapping?
Start by simply grinding the taper onto the tip of the bolt. The next step is to add vertical grooves into the threads. You can add 3 or 4 grooves, depending on the size of the bolt. These grooves help in adding a sharp edge to the threads of the bolt when screwing the bolt. The next step is to drill a hole in the equipment and affix it securely.
Are Stainless Steel Self-tapping Screws Rust Proof?
Stainless steel self-tapping screws are designed with a superior chemical composition. This allows them to exhibit excellent corrosion resistance properties, thereby preventing rusting. The screws are, however, prone to rust when exposed to moisture continuously. When these screws are exposed to high temperatures continuously, they are prone to rust.

Self Tapping Screw Vs Self Drilling Screw
Self-tapping screws tap their own threads, but cannot bore through metal and require a pilot hole. Self-drilling screws dispose of the require for a pilot hole, but can tap as well. These screws are not conversely, and mixing up the two can cause many headaches or possible failures within the field.
