Hospa Screw, Chipboard, Pan Head, PZ, Fully Threaded, Galvanized

How do I know these screws will fit my application?

Please check the dimensions on the listing. This Hospa screw is 13 mm long with a 3.5 mm thread diameter and a 7.0 mm head diameter. It is designed for a PZ2 drive, which means your drill or screwdriver should match the same bit size for good engagement.

What drive type and bit should I use?

These screws use a PZ cross slot drive. You should use a PZ2 bit or driver to help prevent cam out and to keep the screw head properly seated during driving.

Are these screws fully threaded or partially threaded?

This model is fully threaded, which helps it hold securely along the full length once the screw is driven. Fully threaded screws are commonly used where you want consistent clamping and grip through the material thickness.

What head style do they have, and will they sit flush?

The screws feature a pan head. A pan head sits with a rounded top and typically does not countersink flush like some countersunk designs. If flush seating is important for your build, compare the head profile to your housing or surface requirements.

How many screws do I get, and are they supplied in a dispenser box?

This pack contains 1000 screws supplied in specially designed dispenser boxes for easier handling and storage. The packing format is an Orga Box, which is convenient for ongoing projects where you want reliable access to the right screw type.

Do they have any corrosion resistance for day to day use?

These screws are zinc plated, which provides a basic level of corrosion resistance for many indoor applications. If your project is exposed to damp or external conditions, it is worth considering the suitability of zinc plated fixings for that environment.
