Double-threaded screw 8x100mm with M8 thread. Quantity in package: 50 pieces. 98100EDR

What is it and when is it useful

The double-threaded screw M8 × 100 mm is a practical solution for installations requiring simultaneous access to wood and metal components. One side features a wood thread – ideal for fastening into beams, posts, or connections with plastic dowels – while the other side has a standard metric M8 thread, enabling the attachment of pipe elements or sanitary fittings. This single component replaces two separate screws, accelerating work both during the assembly of wooden structures and the installation of water and sewage systems.

Key features and benefits

• Zinc coating – protects against corrosion even in humid conditions, extending the service life of the connection.
• External hexagon located in the middle of the screw ensures a secure grip with an 8 mm open-end wrench, facilitating precise tightening without slippage.
• Torx (TX) socket at the end enables quick work with a screwdriver, reducing assembly time and minimizing strain on the installer's hand.
• Double-sided thread:
  • Wood thread – excellent for direct screwing into wood or for use with plastic dowels in various base materials.
  • Metric thread M8 – allows secure fastening of pipes or sanitary fittings in plumbing installations without additional mounting elements.
• Versatility – a single screw can simultaneously secure structural components and piping systems, reducing the number of parts required in the kit.

Installation and compatibility

1. Preparation – select a location in the wood or near the pipe that requires connection; ensure the hole has the appropriate diameter for the wood thread.
2. Positioning – orient the wood thread toward the wooden material and the metric thread toward the pipe element.
3. Tightening – use an 8 mm open-end wrench or a screwdriver with a Torx bit; thanks to the central hexagon, you will achieve uniform torque and avoid damaging the thread.

Packaging of 50 pieces provides a convenient supply for larger construction and installation projects, while also allowing quick replenishment of missing components on the construction site.
