Use and selection
This chipboard-screw type is distinguished by its countersunk head and Type 17 point. Describe the board and supporting timber or other receiving material so the point, thread and seating arrangement can be reviewed together. The size table is a catalogue reference for nominal diameter and length; use the joint drawing to specify the particular length and thread arrangement needed.
