Product Description

This highly customisable anti‑theft screw series is based on an ST 3.5 self‑tapping thread (approx. 3.5mm diameter). The drive can be three holes (tri‑grove), H‑shape, or Y‑shape, depending on your security requirement. The finish is either black zinc plating or nickel plating – black zinc offers a dark, non‑reflective surface, while nickel provides a bright, decorative look. The screws are hardened carbon steel for good mechanical strength. As a customised product, the size, head shape (pan, flat, truss, etc.), and drive geometry can be tailored to OEM specifications. These screws are ideal for self‑tapping assembly into plastic, wood, or thin metal sheets where theft prevention is needed.
