Self-drilling screw, pan head | Zinc-plated | DIN 7504N
This pan head self-drilling screw is manufactured from hardened, zinc-plated (FZB) steel, which provides good durability and basic corrosion protection for dry indoor environments. The screw is designed to provide stable and secure fastening in both metal and wood.
FIELD OF APPLICATION
The self-drilling screw is primarily used for fastening in metal structures and woodwork. Its steel construction makes it ideal for indoor use. The pan head offers a smooth and aesthetic finish, which is beneficial for visible installations.

FREQUENTLY ASKED QUESTIONS (FAQ)
What is the benefit of a self-drilling screw and how does the drill point work?
A self-drilling screw has an integrated drill point that drills its own hole and forms its own threads in a single operation:
-
Significantly reduces work time: You avoid pre-drilling and changing tools, which saves a huge amount of time when installing sheet materials, profiles, and sheet metal.
-
Secure and play-free fastening: Because the screw threads directly into the self-drilled hole, a perfect fit with high pull-out strength is achieved.
-
Versatile use: Works excellently for attaching thin sheet metal to steel profiles, sheet metal to wood, or harder sheet materials to metal and wood studs.
What does it mean that the screw has a pan head and is made of FZB steel?
-
Pan head: The rounded head provides a wide contact surface against the substrate. It effectively distributes clamping force and prevents the screw from pulling through thinner sheets or damaging softer materials.
-
Zinc-plated steel (FZB / C1-C2): The screw is made of hardened carbon steel so that the drill point can cut through metal. The zinc layer (FZB) provides good basic protection against rust and wear in dry indoor environments, as well as in heated buildings and protected structures.
What should be considered when installing self-drilling screws?
-
Adjust the speed of the screwdriver: Drill with even pressure and medium speed. Too high a speed can burn the drill point before it has penetrated the metal.
-
Respect the maximum drilling capacity: Check the screw's approved drilling range (e.g., max 2.5–3 mm steel plate) so that the material thickness does not exceed the cutting length of the drill point.
-
Use the correct bit: The screw is usually equipped with a Phillips or Torx drive. Ensure you use the correct bit type so that you do not slip and damage the corrosion protection on the head.
