4.2mm x 50mm Torx Countersunk Self Drilling Screw | DIN 7504OT | A2 Stainless Steel
Providing drilling, thread forming and fastening in one operation, this 4.2mm x 50mm self threading metal screw is designed for compatible metal assemblies. The T20 recess gives controlled tool engagement and the countersunk head creates a neat low-profile finish when seated correctly. 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.
