Self tapping screw truss head with flange pozi cross recess with point

Thread and Pitch

DIN 968-C self-tapping screws are designed for direct fastening into sheet metal and rolled metal sections through simple drilling, without the need for pre-threading or tapping operations.
The self-tapping thread, extending along the shank, allows the screw to form its own mating thread in the material, ensuring fast, precise, and stable fastening over time.
For proper installation, particular attention must be paid to the correct pilot hole diameter: a hole that is too small does not necessarily provide better holding strength and may compromise the fastening performance. Drilling tables provide general guidelines only; fastening performance must always be verified according to the specific technical and mechanical conditions of the application.
These screws are primarily intended for sheet metal applications and are not particularly suitable for die-cast materials or certain technical plastics.

Head Type and Drive

The pan head with integrated stamped washer (flange head) provides a larger bearing surface compared to a standard pan head, improving load distribution and fastening stability.
The increased head diameter also allows coverage of through-holes, making it ideal for “sandwich” assemblies between two sheet metal parts. The low-profile, smooth-edged design makes it suitable for visible applications, ensuring a neat and professional appearance.
The Pozidriv cross recess offers improved torque transmission compared to the traditional Phillips drive, reducing the risk of cam-out and enabling more controlled and efficient tightening with manual or power tools.
