Description
Zinc-plated countersunk timber screw TX25 4.5×45 mm – partial thread – pack of 500

The countersunk timber screw with a Torx TX25 drive is a fastener for timber structures. The countersunk head sits flush with the surface of the wood, while the steel shank is protected by an electro-zinc-plated coating.
This listing is for one pack of 500 partially threaded screws measuring 4.5×45 mm. Screws of this design are used where timber components need to be pulled together and the head must not protrude above the surface.
Applications and selection
- Joining timber structural components in carpentry work
- Installation in wood wherever the head needs to sit flush with the surface
- Driving with a power screwdriver and a Torx TX25 bit
- Indoor applications and locations where an electro-zinc-plated coating provides sufficient protection

A Torx drive generally holds the bit more securely than a conventional cross-head drive, making it easier to drive the screw while applying greater pressure. The TX25 size is matched to screws with a diameter of 4.5 mm.
Low-carbon steel with an electro-zinc-plated finish is a common combination for timber fasteners used in dry environments. The partial thread, which leaves part of the shank smooth, allows the component being joined to be pulled tight against the supporting material.
Key benefits at a glance
- Countersunk head for installation flush with the surface of the wood
- Torx TX25 drive for secure bit engagement

Selecting the size
The screw dimensions are specified by its diameter, overall length and thread length. When selecting a screw for a particular joint, consider the thickness of the timber components so that the thread anchors securely in the receiving component.

The bulk pack contains 500 screws, and this listing corresponds to one such pack.
