Bugle Head Drywall Screw Coarse ZP

 Product Description and Name

• Standard Name: Drywall Screw, Bugle Head, Coarse Thread, Zinc Plated.

• Common Chinese Name: Bugle Head Coarse Thread Drywall Screw, Electrogalvanized Drywall Screw, Zinc-Plated Coarse Thread Self-Tapping Drywall Screw.

• Product Definition: A specialized screw designed to secure drywall or plasterboard to wooden studs. Key features include: a bugle head that countersinks smoothly without tearing the surface paper; coarse thread for rapid penetration and strong grip in wood; and a zinc plating (ZP) surface for basic rust protection. Typically installed using a Phillips screwdriver.

Bugle Head Drywall Screw Coarse ZP Key Features

• Bugle Head Design: The bugle head gradually embeds into the paper during installation, preventing

  tearing of the drywall surface and ensuring a smooth finish for easy putty application.

• Coarse Thread: The sparse, coarse threads are ideal for securing to wood joists, providing excellent

  grip and quick engagement.

• Zinc Plated (ZP): Provides basic rust protection and a metallic sheen, suitable for dry indoor environments.

• Drive Type: Typically Phillips head (#2 point), easy to drive with a power screwdriver and prevents slippage.

• Various Sizes: Commonly #6 or #8 diameter, length 1"-3" (25-75mm), sharp self-tapping tip.

Working Principle

• Self-Tapping Entry: The tip penetrates the drywall, and the coarse thread cuts and compresses the

  board and wood joists, creating a strong grip.

• Head Embedding: The flared head gradually sinks into the paper surface, generating axial clamping

  force to secure the board without protruding from the surface.

• Load Distribution: Coarse teeth deeply grip the wooden joists, evenly distributing pressure to prevent

  loosening; the zinc plating reduces friction and improves installation efficiency.

• Installation Control: Use a screwdriver to control the depth, avoiding excessive depth tearing the paper or

  insufficient depth causing instability; the principle involves material compression and friction interlocking.

Product Applications

• Interior Decoration: Fixing drywall to wooden joists, ceiling or partition construction.

• Home DIY: Quick and reliable wall panel installation, cabinet fixing or repair.

• Commercial Buildings: Office or shop partitions, providing a smooth surface for easy finishing.

• Furniture Manufacturing: Lightweight panel connections, economical for non-humid environments.

• Timber Structure Auxiliary: Combined with drywall systems with timber frames, ensuring stability.
