Torx With Pin Drive Two Snake Eyes Flat Pan Csk Head Anti-theft Safety Tamper Proof Security Metal Screw Half-thread

Torx With Pin Drive Two  Snake Eyes Flat Pan Csk Head Anti-theft Safety Tamper Proof Security Metal Screw Half-thread

This versatile security screw is offered with a choice of two different tamper‑resistant drives: Torx with centre pin (pin‑in‑Torx) or two‑hole snake eyes. The head can be flat (countersunk), pan, or CSK (countersunk) depending on the application. A key feature is the half‑thread design – the upper portion of the shank is unthreaded, acting as a pilot or allowing free rotation in clearance holes. Materials vary but typically stainless steel or hardened carbon steel with anti‑corrosion coating. This screw is designed for situations where the fastener must be removed only by authorised personnel and where a smooth unthreaded shank improves alignment or shear strength.
