5.5mm x 25mm Pozidriv Countersunk Self Drilling Screw | DIN 7504OZ | A2 Stainless Steel
This 5.5mm x 25mm Pozidriv self tapping screw for metal is suited to HVAC panels, ducting accessories and fabricated fittings where a raised screw head could interfere with another panel, cover or moving component. The self-drilling point can reduce separate pilot-drilling operations in suitable metal while the countersunk head finishes level with the prepared surface. 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
- Metal Brackets: Secures suitable brackets and support fittings while keeping the installed head low to the surface.
- Equipment Covers: Fastens removable covers and access panels where a protruding screw head could obstruct adjacent parts.
- Light-Gauge Steel: Joins compatible thin metal sections using the integrated drill point and self-tapping thread.
- General Construction: Provides a flush metal fixing for suitable fabricated accessories, panels and interior metalwork.
