Extrusion screw tap and cutting different point without cutting discharge as its characteristics of teeth, and the internal thread processing surface pressure created beautiful appearance. Smooth. Material wire continuous no cutting, thread strength increased by about 30%, the precision is stable, because of the extrusion die of wire diameter psychological endurance, torsional strength. The tap life long is not easy to break. Materials with great extensibility.

Because of the particularity of extrusion screw tap, screw extrusion and Cutting Tapping the bottom of the same size compared to. So please before use according to the specifications of purchase confirmation right bottom or it will cause the gage unqualified.

A simplified formula for the company to provide for the use of the bottom:


Metric screw extrusion wire tapping hole diameter = - wire tapping from /2 such as M3X0.5 underport 3-0.5/2=2.75;
