How to use

Select an appropriate pilot hole diameter for the wood type and screw diameter to reduce splitting and ensure correct thread engagement. Position the screw and drive it with a compatible bit or screwdriver at steady speed, applying moderate pressure until the head sits flush or to the desired depth. When joining two wooden parts, clamp pieces if necessary to maintain alignment during driving. For repeated use in hard or dense wood, pre-drilling to the pilot diameter recommended to ease installation and protect the screw drive.

Usage recommendations

For best results, match pilot hole size to the wood species and avoid overtightening to preserve holding strength. If used outdoors or in humid environments, consider additional corrosion protection or selecting screws with specified coatings suitable for exterior use.
