5.5mm x 50mm Security Torx Pan Head Self Drilling Screw | Security Torx | Delta Protekt® Hardened Steel

This 5.5mm x 50mm Security Torx pan head self drilling screw is designed to drill, form a mating thread and fasten into compatible metal in one installation process. The hardened drill-shaped point helps reduce the need for a separate pilot hole in suitable sheet metal, brackets, panels and fabricated components. The hardened steel construction with Delta Protekt® finish is intended for robust fastening applications where a coated steel screw is preferred.

What Are Pan Head Self Drilling Screws?

Self Drilling Screws use a hardened drill-shaped point to penetrate suitable metal before the screw thread engages. Pan head versions are useful where a visible low-profile head and good clamping area are preferred over a countersunk finish. The Security Torx drive is designed to require a matching security bit and helps discourage casual removal.

Common Applications

  • Metal Brackets: Fastens brackets and support fittings to compatible sheet or light-gauge metal sections.
  • Equipment Covers: Secures removable covers and access panels where a pan head provides a broad bearing surface.
  • Signage and Displays: Provides a neat fixing for suitable metal signs, frames and display components.
  • Light Engineering: Supports general non-critical assembly of compatible metal parts and fabricated components.
