4.2mm x 22mm Torx Countersunk Self Drilling Screw | DIN 7504OT | A2 Stainless Steel
Made for efficient metal assembly, this 4.2mm x 22mm self drilling 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?
Self Drilling Countersunk Screws are metal fasteners that can drill and fasten during the same installation process in suitable materials. Their tapered head is designed to sit level with or below the surrounding surface which helps maintain clearance around covers, panels and adjoining components.
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.
