- Application
- Suitable Ductile Metal Assemblies
Trilobular thread-forming screws are designed to form internal threads in suitable ductile metal components during assembly.
Their three-lobed thread geometry allows the screw to form mating threads in properly designed pilot holes, potentially reducing the need for a separate tapping operation.
Typical applications include electrical equipment, industrial housings, metal brackets and OEM assemblies.
Hextro supports custom trilobular thread-forming screws based on customer drawings, samples and assembly requirements.
Product Features
- Trilobular thread-forming geometry
- Pan head, flange head and other specified designs
- Torx, Phillips and other drive options
- Steel material and heat-treatment requirements according to the application
- Zinc plating and other specified surface finishes
Application and Technical Considerations
Thread-forming performance depends on the mating material, pilot-hole dimensions, screw geometry and installation conditions.
The screw must be compatible with the metal component and the intended assembly process.
Driving torque, stripping torque, thread engagement and joint performance should be evaluated according to project requirements.
Quality Inspection
Important inspection points may include dimensions, thread geometry, hardness, surface finish and agreed functional tests.
Request a Quotation
Please send the drawing or sample, thread specifications, head and drive requirements, mating material, pilot-hole dimensions, quantity and finishing requirements.
Hextro supports technical clarification, manufacturing coordination and quality inspection follow-up.
