5.5mm x 40mm Torx Countersunk Self Drilling Screw | DIN 7504OT | A2 Stainless Steel
This 5.5mm x 40mm Torx self threading metal screw is suited to control cabinets, equipment housings and mounting brackets where a raised screw head could interfere with another panel, cover or moving component. The self-drilling point can reduce separate pilot-drilling operations in suitable metal while the countersunk head finishes level with the prepared surface. 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 Tapping Screws with an integrated drill point can reduce separate drilling and tapping stages in compatible sheet metal. Once the point has penetrated the material, the thread engages the metal and the countersunk head seats into a matching recess.
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.
