The "gimlet" point of wood screws is a "pinch point" that is produced by a special threadroll die that shears off a very small portion of the end of the (square-ended) headed blank and produces the finished point. As the square-ended blank is produced in a "straight hole" ("non-pointing&quot die, different blank (and screw) lengths of the same diamter can be made in the same die.
