Hospa Screw, Chipboard, Raised Head, with PZ Cross Slot, Fully Threaded

Product Details

What does the 3.5 x 15 mm size mean?

This screw is supplied with a thread diameter of 3.5 mm and a length of 15 mm, which helps you match it to the correct pilot hole and timber or board thickness. For best results, choose a fastener length that fully secures the joint without bottoming out.

Is this screw suitable for outdoor or damp conditions?

Yes, it is galvanized, which provides corrosion resistance for many common installation situations. While it is well suited to environments where moisture may be present, always consider your specific exposure level and follow any project guidelines.

Will it work with a Pozi drive bit?

These screws use a PZ cross slot drive, designed to be used with Pozi (PZ) bits. Using the correct bit helps improve grip and reduces the risk of cam out during driving.

What head style is it and where is it typically used?

The screw has a raised head, which sits on the surface and is commonly used where you need a secure fixing with a head that remains visible above the material. This can be helpful for holding components firmly during assembly.

How many screws are included in the pack?

You receive 1000 screws per pack, supplied in an Orga Box. This bulk quantity is useful for repeat jobs, workshops, and projects where consistent sizing matters.

Is the screw fully threaded?

Yes, it is fully threaded, meaning the threads run along the full length of the screw. This generally provides strong pull power through the entire fixing, which is beneficial for secure fastening in construction and renovation tasks.
