What is a 'Pozi' head?

Can I use these screws for interior projects?
While the screws can be used in some interior applications, they are primarily designed for outdoor use due to the green coating and weather resistance properties.
How many screws are in a box?

What is the colour of these screws?

Troubleshooting
Screw head snapping off during installation.
Reduce driving speed, ensure the drill bit is correctly aligned, and pre-drill pilot holes if necessary.
Screw not going in flush.
Ensure the pilot hole is the correct size. If the screw still won't sit flush, try using a countersinking bit or applying more pressure while driving.
Wood splitting when inserting the screw.
Always pre-drill pilot holes, especially when using hardwoods, and adjust driving speed.

Setup, Compatibility & Care
Setup:
Preparation: Ensure the timber is clean and dry.
Pre-Drilling: Pre-drill pilot holes, particularly when working with hardwoods, to prevent splitting. The drill bit should be slightly smaller than the screw's core diameter.
Driving the Screws: Use a drill with a Pozi-compatible bit. Drive the screws straight into the wood until the head is flush with the surface.
Compatibility:
Compatible with most types of timber commonly used in decking and fencing, including treated softwood.
Compatible with Pozi-drive bits.
Care:
Regularly inspect your decking and fencing for loose screws, and tighten them as needed.
If the screws are exposed to harsh conditions, consider applying a wood sealant or stain to the surrounding timber to further protect the screws.
