Woodspur torx, self-piloting, self-countersinking screws: https://cdn.axminstertools.com/media/catalog/product/cache/6aa9e1e59bcc5998e1687ab5ba3e27a4/5/0/503323_xl.jpg https://cdn.axminstertools.com/media/catalog/product/cache/6... The tip is scalloped and sharp for precise driving and piloting, the threading is also sharp, as is the profiled head which does a very good job of counter sinking into soft timber. They are so sharp in fact that it’s very easy to accidentally drive them an inch deep. Comes wax lubricated in zinc plated or A4 marine stainless for external use.
