Product Introduction
Standard Name: Pan Head Self-Tapping Screw, Nickel Plated.
Common Names: Nickel-Plated Pan Head Self-Tapping Screw, Nickel-Plated Flat Pan Head Self-Tapping Screw.
Product Definition: A screw featuring a rounded pan head and a tapered or extruded point at the shank end. It eliminates the need for pre-drilled threaded holes, enabling self-tapping into thin steel sheets, aluminum, plastics, and similar materials to form connections through a single-step fastening process. Its nickel-plated surface provides excellent corrosion resistance, a bright decorative finish, and moderate wear resistance.
Self-Tapping Screw Pan Head Nickel Key Features
Pan Head Design: The slightly curved cylindrical head provides a large pressure surface and an
aesthetically pleasing appearance. Its slightly protruding surface facilitates torque application.
Nickel Plated Coating: Provides excellent corrosion protection, abrasion resistance, and a bright silver
finish, enhancing conductivity and aesthetics, suitable for electronic or decorative applications.
Self-Tapping Thread: Sharp tip, thread design cuts through the material to form an internal thread,
eliminating the need for pre-tapping.
Drive Type: Commonly Phillips or slotted drive for easy actuation.
Material and Specifications: Commonly carbon steel, various specifications (e.g., M2-M6), medium strength.

Working Principle
Self-Tapping Entry: The tip penetrates the material, cutting a matching internal thread.
Preload Generation: Rotation applies torque, generating axial clamping force, with the pan head evenly
distributing pressure.
Protection and Efficiency: The nickel plating reduces friction, improves corrosion resistance, and
enhances appearance.
Installation Control: Precise depth using a screwdriver avoids overtightening and material damage;
the principle involves material cutting and friction interlocking.

Product Applications
Electronics and Appliances: Secure panels, housings, or circuit boards; nickel plating enhances
conductivity and aesthetics.
Metalworking: Connect thin metal sheets or plastic components; easy self-tapping.
Automotive and Instrumentation: Interior trim or lightweight mounting; corrosion-resistant for
interior environments.
Furniture and Decor: Assemble metal fittings; aesthetically pleasing and shiny.
DIY and Repair: Quickly fasten thin materials in everyday projects.
