It is a widely used screw for woodworking and consists of 3 parts: bugle head, single-start/high-low thread, and TY-17/TY-168 cut point.
* Recess with an appropriate depth provides a stable driving-in process.
* TY-168 cut point is designed for enhancing the cutting efficiency and can easily drill through the knots or growth rings in boards with high density.
* The single-start/high-low threads can improve the pull-out resistance of threads
