4.2mm x 25mm Torx Countersunk Self Drilling Screw | DIN 7504P | Steel BZP
Designed for electrical enclosures, mounting plates and access panels, this 4.2mm x 25mm metal self tapping screw combines an integrated drill point with a self-tapping thread and countersunk head. The T20 drive provides the specified tool engagement while the tapered head helps reduce protrusion once installed into a suitable countersunk recess. The BZP Steel construction provides a zinc-plated finish for general indoor and suitably protected metal fastening 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.
