Iron Type 2 Grooved + Bind Tapping Screw Trivalent Chromate
This is a screw that can be directly tightened into a pilot hole that has not been processed with internal threads by plastically forming internal threads in the counterpart material itself. The screw pitch is finer than that of type 1 tapping screws, with the tip of the screw cut by 1/4, and the cut part acts as a blade to shape the internal threads by cutting into the counterpart material. Usable counterpart materials include thin and thick plates (0.4 to 5mm or less), non-metals, thermosetting resins, etc. It is compliant with EU-RoHS standards.
