How to use

Pre-drill pilot holes as required by the wood type and screw diameter to reduce splitting, especially near edges or in hardwoods. Position the screw perpendicular to the workpiece and drive it in using a compatible screwdriver or power driver set to an appropriate torque to avoid overdriving. For visible surfaces, countersink the head if a flush finish is required and use appropriate plugs or fillers for aesthetic finishing.

Recommendations

For best results, match pilot hole diameter to the core diameter of the screw and select a driving speed and torque suitable for the wood species. When used outdoors or in high-humidity environments, verify the metal finish or corrosion resistance is suitable for the exposure conditions; apply additional protective treatment if necessary.
