Custom Large Flat Head Phillips Self-Tapping Screws
Hetai – Custom Fastener Manufacturer
Hetai Custom Large Flat Head Phillips Self-Tapping Screws are precision-engineered fastening components designed for applications requiring a wide bearing surface, secure thread engagement, and a clean Phillips drive. The large flat head distributes clamping force over a broader area, helping reduce surface pressure and improving fastening stability on sheet metal, plastics, wood, and other materials.
Manufactured according to customer drawings, samples, or application requirements, these screws can be customized in diameter, length, thread specification, head dimensions, drive type, material, and surface finish.
Large Flat Head Design
The enlarged flat head provides a larger contact area than a conventional flat-head or pan-head screw. This design helps distribute the fastening load and can provide better retention when securing thin panels, brackets, covers, and other components.
The Phillips recess allows convenient installation using standard Phillips screwdrivers or power tools, making the screws suitable for efficient assembly and production-line applications.
Self-Tapping Thread
The specially formed self-tapping thread enables the screw to create its own mating thread during installation. This can simplify assembly and eliminate the need for a pre-threaded hole in many applications.
Depending on the material and application, Hetai can customize the thread profile, pitch, tip geometry, and thread length to achieve the required installation performance.
