Hospa Screw, Chipboard, Countersunk Head, with PZ Cross Slot, Fully Threaded, St

Product Details

Is this screw suitable for general household and trade use

Yes. Hospa Scr Ful Csk PZ2 D4.0x55mm is a multi purpose screw designed for everyday fastening tasks where a countersunk finish and reliable hold are needed.

What head style does the screw have and why does it matter

Countersunk head allows the screw head to sit flush or near flush in compatible materials. This is useful for cleaner finishes on wood and timber based applications.

Which screwdriver or bit do I need

You will need a PZ cross slot driver or bit. This matches the screw drive type and helps improve grip and reduce the risk of cam out during installation.

How do I confirm the correct size before ordering

The key size details are length 55 mm and thread diameter 4 mm. Checking these against your project requirements helps you select the right fastener length for the depth you need.

Is the thread fully threaded, and what difference does that make

Yes, it is fully threaded. Fully threaded screws typically give a more consistent grip along the full length that enters the material, which is helpful when you want a secure hold.

Is the screw protected against corrosion

Galvanised coating provides corrosion resistance for many indoor and protected outdoor uses. For fully exposed marine or very harsh environments, it is still best to check suitability for your conditions.

How many screws are included in the box

This product is supplied as an orga box containing 200 screws. It is a practical quantity for repeat jobs, small site work, or stocking a tool bag.

What projects is this screw commonly used for

Given the countersunk head, PZ drive, and 55 mm length, it is commonly chosen for timber fastening tasks such as fixing boards, securing components, and applications where a neat, flush style finish is preferred.
