4.2mm x 22mm Torx Countersunk Self Drilling Screw | DIN 7504P | Steel BZP
Made for efficient metal assembly, this 4.2mm x 22mm metal self tapping screw uses a drill-shaped point to penetrate compatible material before its thread forms a mating path. The 8.1mm head diameter and 2.50mm 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?
Countersunk Self Drilling Screws combine a drill point, self-tapping thread and tapered head in one fastener. The point creates the installation hole in compatible metal, the thread forms its mating path and the countersunk head seats into a prepared recess for a flush finish.
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.
