Dual Drive Design
Slotted recess provides a backup drive option for manual adjustment or removal in confined spaces.

DIN 7504N and DIN 7504M are essentially the same product. Their technical specifications, dimensions, and applications are identical, and the corresponding international standard for both is currently ISO 15481.
The main differences lie in the head style and intended applications. DIN 7504N is a standard fastener, while DIN 7504M is generally regarded as an improved version of the N type, featuring an additional bearing surface for washers.


1. No pre-drilling required
The self-tapping tip penetrates metal sheets directly, simultaneously forming the mounting hole and the mating threads, enabling one-step installation and improving construction efficiency.
2. Pan-Head Design
The larger contact area of the head provides better clamping force, making it suitable for applications that do not require countersunk installation.
3. Phillips Drive
Features a Phillips (PH) drive, suitable for quick installation with power tools, ensuring high assembly efficiency.
4. Suitable for Thin-Sheet Connections
Particularly suitable for connecting thin metal sheets to metal frames, such as in steel structures, ventilation ducts, and equipment enclosures.
Slotted recess provides a backup drive option for manual adjustment or removal in confined spaces.
Built-in washer face distributes load evenly and helps protect the fastening surface.
The pan head design provides a larger bearing surface, distributing pressure evenly and ensuring a stable, reliable connection.
Compared to the 7504K with an external hex head, the 7504N features a pan head with a rounded surface and no raised edges on top. Once tightened, it offers a more aesthetically pleasing appearance and is less likely to snag on clothing or hands, making it ideal for use in exposed applications.
Both DIN 7504M and DIN 7504N belong to the DIN 7504 series of self-drilling screws. The main difference between them lies in their head styles and intended applications. DIN 7504N is a standard fastener, while DIN 7504M is generally considered an improved version of the N type, featuring an additional bearing surface for washers.
In most cases, yes. Because it has a larger contact area at the head, DIN 7504M generally provides better clamping performance, but you need to confirm that there is sufficient installation space.
It is mainly used for thin steel sheets, aluminum profiles, light-gauge steel, and other metal materials.
