Hospa Screw, Flat Head, PZ, Fully Threaded, Galvanized

Product Details

Is this screw suitable for use with a PZ2 driver?

This Hospa screw is designed for a PZ2 drive. Using the correct driver helps improve grip in the cross recess and reduces the chance of cam out, which is useful for clean, accurate installation.

What does the size 3.5 x 30 mm mean?

The 3.5 mm refers to the thread diameter and the 30 mm refers to the screw length. This makes it a good choice for applications where you need a 30 mm fixing with a 3.5 mm thread.

Does the flat head work for flush fitting?

Yes, this model has a flat head to help the screw sit neatly against the surface. It is intended for installations where a low profile fixing is preferred.

Is the screw fully threaded or partially threaded?

This screw is fully threaded. A fully threaded design typically offers more consistent grip along the full length, which can be helpful in timber based and sheet material fixings where strong pull through resistance is important.

What type of coating is used and does it resist corrosion?

The screw is zinc plated. Zinc plating is commonly used to improve resistance to corrosion compared with uncoated steel, making it suitable for many indoor and light duty environments.

How many screws are included in the pack?

The pack contains a 1000 pack of screws. Supplied in an Orga Box format, it is convenient for job sites and workshops where you want steady supply and easy storage.

Will I need a washer with this screw?

This version is supplied with washer head. The integrated washer head style helps provide a wider bearing surface, which can assist with securing materials without the need for a separate washer in many standard installations.

Is there a guarantee on these screws?

These screws come with the Hafele Lifetime Guarantee of 25 years. This offers added reassurance when stocking or specifying fixings for long term projects.
