4.2mm x 45mm Torx Countersunk Self Drilling Screw | DIN 7504P | Steel BZP
Designed for signage, display equipment and metal framework, this 4.2mm x 45mm self drilling metal screw combines an integrated drill point with a self-tapping thread and countersunk head. The T20 drive provides the specified tool engagement while the tapered head helps reduce protrusion once installed into a suitable countersunk recess. The BZP Steel construction provides a zinc-plated finish for general indoor and suitably protected 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.
