4.2mm x 38mm Torx Countersunk Self Drilling Screw | DIN 7504OT | A2 Stainless Steel
Providing drilling, thread forming and fastening in one operation, this 4.2mm x 38mm countersunk self drilling 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?
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
- 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.
