Wood Screw ZP Phillips

Product Introduction

• Standard Name: Wood Screw, Zinc Plated, Phillips Drive.

• Common Names: Zinc-Plated Wood Screw, Electro-Galvanized Wood Screw, Phillips Head Wood Screw.

• Product Definition: A fastener specifically designed for wood-to-wood connections. Features include a pointed tip for easy penetration into wood, coarse threads providing strong grip without requiring nuts, and a Phillips drive. The surface undergoes zinc plating (ZP) treatment for basic rust resistance, suitable for standard indoor or dry outdoor environments.

Wood Screw ZP Phillips Key Features

• Zinc Plated (ZP): Provides basic rust protection and a bright silver finish, enhancing corrosion resistance,

  suitable for indoor or slightly damp environments.

• Phillips Drive: Phillips head design facilitates drive with electric screwdrivers, preventing slippage and

  improving installation efficiency.

• Coarse Thread Construction: Coarse, sparse threads with a sharp tip, self-tapping into the wood,

  providing excellent grip; common head types include flat, round, or pan head.

• Material and Strength: Commonly made of carbon steel, medium strength; various sizes available

  (e.g., #6-#12 diameter, 1/2"-4" length).

• Advantages: Strong grip, economical, easy to install, but requires pre-drilling pilot holes to prevent

  wood splitting.

Working Principle

• Self-Tapping Entry: Tip-guided, coarse threads cut and compress the wood fibers, forming a strong

  threaded groove.

• Pre-tightening force generation: When torque is applied, the head tightens the surface, generating

  a strong axial clamping force.

• Grip and distribution: The coarse threads deeply grip the wood, evenly distributing stress to prevent

  loosening; the zinc plating reduces friction and improves efficiency.

• Installation control: The cross-groove design ensures precise drive, preventing over-tightening and

  cracking of the wood; the principle involves material compression and frictional gripping.

Product applications:

• Furniture manufacturing: Provides stable connections for assembling tables, chairs, cabinets,or bed frames.

• Woodworking and DIY: Economical and reliable for home repairs, board fixing, or project assembly.

• Interior finishing: Installs wood frames, doors, windows, or trim strips; the zinc plating is suitable for

  dry environments.

• Construction aids: Secures lightweight wood structures such as fences or trellises.

• Industrial wood products: For bulk timber assembly; the cross-groove design facilitates rapid construction.
