Product Overview
This product is a multi‑functional self‑tapping screw with yellow zinc coating, made of heat‑treated C1022 carbon steel, featuring a PH2 cross recess, bugle countersunk head, double‑thread design, and T17 cutting point.

It is a general‑purpose fastening accessory for home ceilings, cabinets, and woodworking applications.
