5.5mm x 50mm Phillips Countersunk Self Drilling Screw | DIN 7504P | Steel BZP
Made for efficient metal assembly, this 5.5mm x 50mm self tapping screw for metal uses a drill-shaped point to penetrate compatible material before its thread forms a mating path. The 10.8mm head diameter and 3.40mm head height define the countersunk profile for this size. The BZP Steel construction provides a zinc-plated finish for general indoor and suitably protected metal fastening applications.
What Are Countersunk Self Drilling Screws?
Countersunk Self Drilling Screws combine a drill point, self-tapping thread and tapered head in one fastener. The point creates the installation hole in compatible metal, the thread forms its mating path and the countersunk head seats into a prepared recess for a flush finish.
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.
