4.2mm x 13mm Security Torx Countersunk Self Drilling Screw | Security Torx | Delta Protekt® Hardened Steel
For machinery guards, housings and equipment covers, this 4.2mm x 13mm Security Torx self drilling screw can create its own entry hole in compatible metal before the thread engages the receiving material. The countersunk profile is useful where clearance, appearance or the positioning of adjacent parts requires a flush fixing. The Delta Protekt® Hardened Steel construction combines a hardened fastener body with a protective coating for demanding metal fastening applications.
What Are Countersunk Self Drilling Screws?
Self Drilling Countersunk Screws are metal fasteners that can drill and fasten during the same installation process in suitable materials. Their tapered head is designed to sit level with or below the surrounding surface which helps maintain clearance around covers, panels and adjoining components.
Common Applications
- HVAC and Ventilation: Secures suitable ducting accessories, covers and fabricated metal fittings where a countersunk finish is required.
- Control Cabinets: Provides a flush fixing for mounting plates, panels and compatible metal components in control equipment.
- Signage and Displays: Keeps the fixing head close to the surface on suitable metal signs, frames and display assemblies.
- Workshop Fabrication: Supports general repairs, prototype work and metal assembly using compatible sheet or light-gauge sections.
