Self-drilling screws (or self-drilling screws) defined in the DIN 7504 standard published by the German Standardization Institute (DIN) are similar to self-tapping sheet metal screws but have a drilling point. This standard eliminates the need for a pilot hole by simultaneously drilling holes in the substrate and creating mating threads.
The standard in question contains different requirements for three types of screws:
In the DIN 7504 standard, the dimensions and requirements for self-drilling screws with lead threads are described and test methods are defined.
In the mentioned standard, the requirements for self-tapping screws are listed under the following headings:
A self-drilling screw is a type of self-tapping screw that also has a drilling point. The sharp drilling point both drills the hole and creates mating threads in a single operation. These types of screws have a point that acts as a drill bit and sharp cutting threads that touch the hole during installation. Self-drilling screws are a commonly used type of screw for quick drilling in both metal and wood. A self-drilling screw is typically identified by its grooved (notched) end. This end acts as a drill bit for the screw, making installation much faster. The notched area on the end also acts as a reservoir to collect chips or metal shavings.
Our organization, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, also provides testing services for self-drilling screws within the scope of DIN 7504 standard, with its trained and expert staff and advanced technological equipment.
