4.2mm x 16mm Torx Countersunk Self Drilling Screw | DIN 7504P | Steel BZP
Designed for light-gauge steel components and overlapping sheet-metal joints, this 4.2mm x 16mm countersunk self drilling 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?
Countersunk Tek Screws are commonly used for metal-to-metal fastening where both self drilling performance and a flush installed head are required. Correct driver size, material thickness and countersink depth are important for secure installation.
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.
