5.5mm x 70mm Torx Countersunk Self Drilling Screw | DIN 7504P | Steel BZP
Made for efficient metal assembly, this 5.5mm x 70mm self threading metal screw 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?
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.
