Double-threaded screw 12x125mm with M12 thread. Quantity per package: 50 pieces. 912125EDR

Universal Wood and Pipe Connection

The double-threaded screw with dimensions 12 × 125 mm combines two thread types – a traditional wood thread and a metric M12 thread. This allows a single component to simultaneously secure a wooden element and mount a piping system, significantly simplifying installation work in residential and industrial buildings.

• Double-sided thread – on one side, screw into wood (e.g., beams, posts); on the other side, screw in pipe clamps or other M12-threaded components.
• External hexagon located at mid-length facilitates manual positioning of the screw before final tightening, speeding up installation even in hard-to-reach areas.
• TX socket at the end ensures a secure grip when using a socket wrench, eliminating the risk of tool slippage.
• Galvanized coating protects against corrosion, making the screw suitable for humid conditions, such as bathrooms or sanitary installations.

Applications and Benefits for Installer and End User

• Installation of piping systems in sanitary zones – the metric thread enables quick and durable mounting of pipe clamps, which is especially important for water and sewage installations.
• Joining wooden and metal components – thanks to the wood thread, beams or panels can be directly attached without the need for additional dowels.
• Single solution for two materials – saves time and space in the tool box, eliminating the need to carry separate screws for wood and metric applications.
• Connection stability – the galvanized surface ensures long-term mechanical strength, reducing the risk of loosening during operation.

Installation and Practical Tips

1. Prepare a hole in the wood with a diameter slightly smaller than 12 mm to ensure strong thread engagement.
2. Screw in the screw manually until the external hexagon is firmly seated; then complete tightening using a socket wrench on the TX socket.
3. Fit pipe clamps onto the M12 thread on the opposite side – simply tighten them for a few turns to achieve a secure connection.
4. Check the tightness of the water or sewage installation before finishing the work; make any necessary adjustments before fully tightening the screw.

The double-threaded screw 12 × 125 mm is a practical solution for every professional who needs a fast and durable connection between wood and piping components in a single step.
