Pan Head Self-Tapping Screws
Product Overview
This screw is a US-standard pan head cross-recess self-tapping screw, a general-purpose fastener widely used in both industrial and civil applications. Manufactured from high-quality carbon steel, it is hardened through heat treatment and finished with a blue‑white zinc plating, providing excellent self‑tapping cutting performance and rust resistance. It is suitable for connecting thin sheets, plastic parts, and medium‑ to low‑density wood. The pan head with Phillips drive combines installation convenience with stable load‑bearing performance, making it a common fastener in furniture manufacturing, appliance assembly, renovation works, and related fields.
Product Applications
Furniture Manufacturing: Ideal for assembling panel furniture, wooden boards, and plastic furniture; the pan head design helps prevent cracking of panels while ensuring connection strength.
Home Appliance & Electronics Industry: Used in the assembly of appliance housings, plastic components, and electronic device enclosures; the short‑length variants are well‑suited for thin‑part connections without interfering with internal space.
Renovation & Construction Engineering: Can be used for temporary or permanent fastening of light steel keels, gypsum boards, and color‑coated steel sheets; the self‑tapping structure improves construction efficiency, and the zinc plating suits indoor humid environments.
DIY & General Maintenance: Widely applied in home renovation, handicraft projects, and equipment repairs as a common fastener for everyday general‑purpose connections.
Product Features
Standardized Dimensions, Stable Performance: Produced in accordance with US standards, compatible with common tools; after heat treatment, it offers high hardness, reducing the risk of breakage or cam‑out, ensuring reliable connections.
User‑Friendly Installation: The pan head provides a large bearing surface that minimizes the risk of cracking panels; the cross recess works with standard screwdrivers or bits for efficient, slip‑resistant operation.
Sharp‑Point Self‑Tapping Efficiency: Eliminates the need for pre‑drilling in many cases—can be tapped directly into wood, plastic, and thin steel sheets, making it ideal for quick assembly scenarios.
Zinc Plating for Rust Protection and Durability: The blue‑white zinc plating forms a protective anti‑corrosion layer, suitable for indoor and mildly humid environments, offering high cost‑effectiveness.
