Description
Countersunk timber screw, zinc-plated, TX25, 4.5×80 mm – partially threaded – pack of 250

The Countersunk timber screw with a Torx TX25 drive is a fastener for timber structures where the head needs to sit flush with the wood surface. It is sold in a pack of 250 screws, giving the installation team a uniform set of screws with identical dimensions.
The screw is made from low-carbon steel with an electroplated zinc coating. The partial thread leaves a smooth shank beneath the head, while the Torx drive accepts TX25 bits, commonly used with timber screws.
Applications and selection
- Joining timber components in wooden structures
- Installations where the head needs to sit flush with the wood surface
- Jobs requiring a large number of identical screws in one pack

Construction and performance
Timber screws of this length are used to join thicker beams or several layers of wood. The countersunk head allows the screw to sit flush in the wood, while the profiled partial thread engages the deeper layer of material. Low-carbon steel with an electroplated zinc coating is a common choice for wood screws, and the golden hue of the coating is consistent across the entire batch.
