Thread-cutting tapping screws
Thread-cutting tapping screws cut the thread into the mating material. Tell us the thread size, point, and application, and we'll review everything before quoting.
What it is and how it works
Tapping screws with cutting geometry at the point that helps create the thread in the mating material.
How it works
The slot or flute cuts material as the screw advances into a prepared hole. The point type affects how the screw starts and cuts the thread.
What sets it apart
The visible slot or flute distinguishes it from thread-forming tapping screws, which form the thread without that cutting geometry.
When it's typically considered
Considered when the requirement specifies a cutting point and a thread that must be created in the assembly.
Substrate and application
A prepared hole and a defined mating material. We review the specific application and chip formation with you.
KEY POINTS TO SPECIFY
Use these references to describe your part and fill in only what you already know.
The point references available to describe your part are Types D (or Type 1), 23, 25, and F. If your drawing calls for a different one, include it in your quote request.
What to send
Share the part number, drawing, or sample part, plus the dimensions, estimated quantity, and any known requirements. If something is still to be defined, note it in your request.
What helps us quote
Point type, thread, dimensions, mating material, head, drive, material, finish, and volume.
What each team can bring
