Bugle Head Drywall Screw Fine Black

Product Description

• Standard Name: Drywall Screw, Bugle Head, Fine Thread, Black (Phosphated) Finish.

• Common Names: Black Fine Thread Drywall Screw, Phosphated Fine Thread Drywall Screw.

• Product Definition: A specialized screw designed for securing gypsum board/drywall panels to metal studs (typically light-gauge steel studs). Key features include: Bugle Head design allows smooth countersinking into panels without tearing the surface layer. • Fine Thread profile facilitates easy penetration into thin-walled metal while providing strong, reliable grip in steel. • Surface typically treated with Black Phosphate finish.

Bugle Head Drywall Screw Fine Black Key Features

• Bugle Head Design: The flat-topped, tapered head gradually embeds into the paper during installation,

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

• Fine Thread: The dense, fine threads are ideal for securing to steel studs, providing superior grip and

  pull-out resistance.

• Black Phosphate or Black Oxide Coating: The matte black finish provides basic rust protection, abrasion

  resistance, and lubrication, reducing light reflection and making it suitable for dry indoor environments.

• Drive Type: Typically Phillips head (#2 point), facilitating electric screwdriver operation and preventing

  slippage.

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

Working Principle

• Self-Tapping Entry: The tip penetrates the drywall, and the fine threads cut and compress the board and

  steel studs, creating a secure 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: Fine teeth grip the metal deeply, providing higher pull-out resistance; the black

  coating reduces friction and improves installation efficiency.

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

  stability; the principle involves material compression and friction interlocking.

  
  

Product Applications

• Interior Decoration: Fixing drywall to metal framing, ceiling or partition construction; fine teeth ensure

  strong grip.

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

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

• Steel Structure Auxiliary: Drywall systems combined with metal frames; the black appearance reduces

  glare.

• Professional Construction: Mass drywall projects, suitable for metal framing environments.
