FAQs
What is the Pozidriv (PZ) drive?
Pozidriv is a screw drive system designed to reduce cam-out and provide a more secure grip for the driver bit, improving torque transfer.
What materials can these screws be used with?
These screws are specifically designed for use with wood. Do not use them with metal, concrete, or other materials.
Do I need to pre-drill holes?
Pre-drilling is recommended, especially in hardwoods, to prevent splitting and to make the installation easier.
What size PZ driver bit should I use?
Use a PZ-sized driver bit that matches the recess in the screw head.
What does 'double countersunk head' mean?
A double countersunk head has a design that allows the screw head to sit flush with the surface of the wood.
Are these screws suitable for outdoor use?
Yes, they can be used outdoors, but ensure the wood is treated appropriately to withstand the elements.
How do I choose the right screw length?
Select a screw length that is long enough to penetrate the materials being joined and provide sufficient grip, but not so long that it protrudes out the other side.
Troubleshooting
Screw head stripped during installation.
Use a new screw. Ensure the correct size PZ driver is used. Apply steady pressure while driving the screw to prevent stripping.
Wood splitting when driving screws.
Pre-drill pilot holes, especially in hardwoods. Reduce the driving speed and pressure.
Screw not seating flush.
Ensure the countersinking is working, and use the correct PZ size bit. Check for obstructions preventing full seating.

Setup, Compatibility & Care
Selection: Choose the appropriate screw length and diameter for your project. Consider the thickness of the wood you are joining.
Pre-Drilling: In hardwoods, pre-drilling is recommended to prevent the wood from splitting. Use a drill bit slightly smaller than the screw's core diameter.
Driving: Use a PZ-sized screwdriver bit or driver. Apply firm, steady pressure when driving the screw.
Finish: Drive the screw until the head is flush with the wood surface. Avoid over-tightening.
Care: Store screws in a dry place to prevent corrosion.
