The Hiatt Countersunk Hard Twin Posi Screws are designed for professional tradespeople and home DIY enthusiasts who require reliable fastening hardware specifically for hardwood applications. These screws excel at providing high-torque driving force and consistent performance, though they are specifically engineered for dense woods, meaning they may be overkill for lightweight or soft materials.

The zinc plating provides corrosion resistance, making them suitable for many outdoor applications, though they are primarily designed for indoor or protected hardwood projects.
While designed for ease of starting, a pilot hole is highly recommended when working with very dense hardwoods to prevent wood splitting.
Use a standard Posi-drive bit that corresponds to the screw head size to ensure optimal torque transfer.
These are specifically engineered for hardwood; while they may work in other materials, they are optimized for the grain density of hardwood.
Keep them stored in their original packaging in a dry environment. If used outdoors, consider an additional sealant or finish over the screw head.
Ensure you are using the correct size Posi-drive bit and apply consistent, firm downward pressure while driving.
Increase the size of your pilot hole or move the fastening point slightly further from the edge of the wood.
Check that the pilot hole is deep enough and verify that you are not using a bit that is too small for the screw head.
For best results, always ensure you are using a correctly sized Posi-drive bit to match the head. While these screws are designed for easy starting, it is recommended to drill a small pilot hole if you are working close to the edge of a hardwood board to prevent splitting. To maintain the life of the zinc plating, avoid using power tools with excessive torque settings that might strip the coating off the head during the final tightening phase. Store in a cool, dry place to prevent premature oxidation.
