4.2mm (No.8) x 55mm, Countersunk Self Drilling Screw (TEK), BZP, DIN 7504

55mm countersunk self-drilling screw

Increase speed and efficiency with countersunk self-drilling screws. A drill-like tip allows the screw to create its own pilot hole. Combined with a self-tapping thread allows improved holding power and a tighter grip compared to traditional screws.

Known as TEK screws they are manufactured with a Phillips countersunk head for installation with a

range of standard tools. The countersunk head also allows for a flush finish to the surface of the material.

Manufactured from steel with a bright zinc plating (BZP) for a medium level of corrosion and conforms to DIN 7504 standards.

An impressive combination that makes for a versatile screw when ease of installation, speed, and reliability are needed.
