Plastobular
Plastobular thread-forming screws for plastic assemblies. Tell us the type of plastic and the application, and we'll review feasibility before quoting.
What it is and how it works
Thread-forming screws with an open profile and lobular body for plastic assembly requirements.
How it works
The profile is intended to form the thread in the material during installation. Body geometry and coarse pitch are specified separately from overall length.
What sets it apart
The open profile and lobular body distinguish it from high-low thread-forming screws and from screws with a cutting point.
When it's typically considered
Considered for plastic fastening requirements where a thread-forming profile is specified or under evaluation.
Substrate and application
Plastic, boss or hole geometry, and installation conditions, always based on the customer's application.
KEY POINTS TO SPECIFY
Use these references to describe your part and fill in only what you already know.
To identify the requirement, confirm the open profile, lobular body, mating material, and hole geometry.
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
Drawing or sample part, mating material, profile or part number, dimensions, head, drive, and quantity.
What each team can bring
