M2.2 M2.3 Two Three Holes Snake Eyes Pig Nose Flat Round Head Security Metal Screw Hardened Carbon Steel Plated With Nickel

This security screw series is offered in M2.2 and M2.3 diameters with either two holes (snake eyes) or three holes (tri‑grove style) drive configurations. The head can be flat (countersunk) or round, depending on the mounting requirement. The base material is hardened carbon steel, which is then plated with nickel for a bright, corrosion‑resistant finish. The hardening process increases mechanical strength, making these screws resistant to drilling or gouging attempts. The two‑hole or three‑hole pattern requires a matching security bit, effectively preventing tampering by standard tools. Ideal for consumer electronics, vending machines, and public infrastructure.
