Product Overview
Product Application
DIN 7504R is a raised countersunk head Phillips self-drilling screw that combines drilling, tapping, and fastening functions into one. It is primarily used for joining thin steel sheets, metal profiles, and metal components.
Its head is intermediate between a pan head and a countersunk head; once installed, it maintains a low protrusion height while providing an aesthetically pleasing finish.
The international standard corresponding to DIN 7504R is ISO 15483.

Key Technical Characteristics
- Head Style: Raised Countersunk / Oval Head (matches the dimensions of DIN 7983 / ISO 7051).
- Drive Type: Primarily Philips cross recess (Type H), though Pozidriv (Type Z) or Torx variants exist.
- Functionality: It features a pilot drill-point tip that drills its own hole, forms its own mating threads, and completes the fastening operation in a single step—eliminating the need for pre-drilling.
- Corresponding International Standard: ISO 15483 (Note: The ST 3.9 size is an exception, as it is unique to the DIN standard and omitted from the ISO equivalent).
Product Advantages
Better Appearance After Installation
The raised countersunk head sits partially flush with the surface, providing a cleaner finish than pan-head screws while maintaining higher head strength than fully countersunk designs.
Strong Holding Power in Metal
Designed for metal-to-metal fastening, the self-drilling point creates precise threads and provides reliable pull-out resistance in sheet steel applications.
Common Questions
What is the difference between DIN 7504R and DIN 7504N?
DIN 7504R features a raised countersunk head for a lower-profile finish, while DIN 7504N uses a pan head that remains above the surface and provides a larger bearing area.
Does DIN 7504R require a pre-drilled hole?
No. The drill-point tip drills and forms threads simultaneously, eliminating the need for pre-drilling in most sheet metal applications.
Which drive type is most common?
The most common drive is Phillips (PH2), providing fast installation with standard screwdrivers and power tools.
What materials can DIN 7504Q fasten?
DIN 7504R is commonly used for:
- Steel-to-steel
- Sheet metal assemblies
- Metal profiles
- Thin-gauge structural components
