Iron Type 1A + Plate Tapping Screw Trivalent Chromate Black

Iron Type 1A + Plate Tapping Screw Trivalent Chromate Black

This is a screw that can be directly tightened into a pre-drilled hole without internal threading by plastically forming the internal thread in the counterpart material. The tip of the screw is pointed, serving as a guide for positioning at the center of the pre-drilled hole and improving the screw's grip. Since it tightens while forming the internal thread through forming (plastic deformation), it is less likely to loosen compared to small screws. Usable counterpart materials include thin steel plates (0.4 to 1.2mm), hardboard, and wood. It is compliant with EU-RoHS standards.
