Spoon Screw Thread

· The threaded portion is the same as the coarse thread, and the head is a flexible head.
· A spoon point is provided on the screw tip portion (similar to the tip of a lance), and an internal thread can be created cleanly since it is screwed in, forming a pilot hole in the opposite material, by cutting just the same thickness as the screw shaft diameter itself
· It takes some time to machine the fitting material at the spoon point when first starting to insert the screw, but it produces a beautiful finish from the fitting material surface without excessive pushing.
· Can be used for all kinds of wood, especially effective for hard materials and wood knots
· It can also be used for thin iron plates of about 0.8 mm
