4.2mm x 25mm Torx Countersunk Self Drilling Screw | DIN 7504OT | A2 Stainless Steel
Made for efficient metal assembly, this 4.2mm x 25mm countersunk metal screw uses a drill-shaped point to penetrate compatible material before its thread forms a mating path. The 8.4mm head diameter and 2.60mm head height define the countersunk profile for this size. The A2 Stainless Steel construction provides good corrosion resistance for general engineering, sheet-metal fabrication and suitable exposed 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.
