This advanced security screw combines a Y‑shaped (triangular) drive with a central pin – often called “Y‑type pin‑in‑torx” or simply “triangular with pin”. The pin blocks standard triangular bits, requiring a special hollowed bit. Manufactured from Super Duplex Stainless Steel (DSS) , which offers superior strength and exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking – far superior to 316. Sizes available: M3, M4, M5. The screw is ideal for harsh environments where both anti‑theft and extreme corrosion resistance are demanded. The Y‑shaped drive provides three points of contact for high torque transmission.
| Industry | Usage |
|---|---|
| Automotive | High-strength applications in engines, heavy-duty machinery, and bridge construction |
| Mechanical | Connecting mechanical parts, circuit boards, engines, transmissions in various industries |
| Energy | Connecting power generation equipment and transmission lines |
| Architectural | Building structures, shipbuilding, and petrochemical equipment |
Offshore platform equipment – DSS resists seawater chloride attack.
Chemical processing plants – exposure to acids and high chlorides.
Desalination plant control cabinets and access covers.
Bridge and coastal infrastructure inspection panels.
Swimming pool and water treatment equipment.
Y‑shaped drive with pin – two‑layer security: unusual recess plus central obstruction.
Super Duplex material – exceptional chloride resistance and high tensile strength (>800 MPa).
High torque capability – three contact points distribute load.
Suitable for extreme environments – offshore, chemical, marine.
Available in M3–M5 – common sizes for instrumentation and panels.
