4.2mm x 45mm Torx Countersunk Self Drilling Screw | DIN 7504OT | A2 Stainless Steel
For sheet-metal panels, covers and fabricated assemblies, this 4.2mm x 45mm 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 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 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
- Sheet Metal Fabrication: Joins panels, overlapping sheets, covers and fabricated components where a flush fixing is preferred.
- Electrical Enclosures: Secures access panels, mounting plates and enclosure components without leaving a prominent raised head.
- Machinery and Equipment: Fastens suitable guards, housings and casings where head clearance needs to be maintained.
- Automotive and Transport: Provides a low-profile fixing for compatible brackets, trim panels and lightweight fabricated components.
