5.5mm x 50mm Security Torx Countersunk Self Drilling Screw | Security Torx | Delta Protekt® Hardened Steel
For sheet-metal panels, covers and fabricated assemblies, this 5.5mm x 50mm Security Torx self drilling screw can create its own entry hole in compatible metal before the thread engages the receiving material. The countersunk profile is useful where clearance, appearance or the positioning of adjacent parts requires a flush fixing. The Delta Protekt® Hardened Steel construction combines a hardened fastener body with a protective coating for demanding 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
- 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.
