5.5mm x 25mm Phillips Countersunk Self Drilling Screw | DIN 7504P | Steel BZP
Providing drilling, thread forming and fastening in one operation, this 5.5mm x 25mm metal self tapping screw is designed for compatible metal assemblies. The PH3 recess gives controlled tool engagement and the countersunk head creates a neat low-profile finish when seated correctly. The BZP Steel construction provides a zinc-plated finish for general indoor and suitably protected metal fastening 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.
