Anodized Self-Tapping Screws

Anodized self-tapping screws are fasteners consisting of a threaded shank with a point or drill tip at the bottom and a head at the top. They are made of steel with an electroplated coating. The main requirements for this type of fastener are set out in GOST 11652-80 and GOST 1180-91.

Typical manufacturing process for anodized self-tapping screws:

• preparation of raw material — drawing, calibration, pickling;
• cold heading on automatic horizontal-type machines;
• thread rolling and application of the electroplated coating by anodic oxidation.

The self-tapping screw can be silver or gold in color depending on the type of material used in anodizing. Recommended for indoor use to fasten structures made of wood and wood-based materials.
