About BlackJax Woodscrews

BlackJax Woodscrews are a twin-thread woodscrew range finished with a black organic coating, specifically designed for use with black ironmongery. They provide a neat, consistent appearance where visible fixings are required, making them a popular choice for decorative timber work and exterior fittings.

The twin-thread design allows for fast installation while maintaining reliable holding strength in timber. BlackJax woodscrews are primarily intended for use in softwood applications, where speed, appearance and consistency are key considerations.

Designed for Black Ironmongery Applications

BlackJax Woodscrews are intended for applications where the screw head remains visible and needs to match black fittings and hardware. They’re commonly used for:

  • Fixing black ironmongery and fittings to timber
  • Decorative timber work where a dark finish is required
  • Softwood timber applications
  • Joinery, fencing and outdoor timber projects
  • General exterior fixing where appearance matters

The black organic finish helps the screw blend neatly with black hinges, brackets and fittings for a professional finish.

Key Design Features

BlackJax woodscrews incorporate practical features to support fast installation and reliable performance:

  • Twin-thread design for faster driving and good pull-out resistance in timber
  • Black organic finish designed to complement black ironmongery
  • 25° sharp point and single lead for fast starts and improved thread acceptance
  • Manufactured for consistent quality and dependable performance
  • Corrosion resistance rated for urban and industrial environments with a low salt atmosphere

All sizes up to and including 30mm are fully threaded, while 32mm and above are partially threaded, making longer screws suitable where draw-up is required.

Where BlackJax Woodscrews Sit in the Range

BlackJax Woodscrews are a specialist, appearance-led fixing option within a wider woodscrew range. They’re designed for applications where the finish of the fixing is just as important as performance.

For general internal fixing where appearance is not critical, a standard zinc woodscrew may be more suitable. For decorative and exterior timber work using black ironmongery, BlackJax woodscrews provide a practical and visually consistent solution.

Trusted Trade Fixings

Our BlackJax Woodscrews are supplied by Timco and selected for reliability, consistent manufacture and suitability for trade applications where both performance and appearance matter.
