The dimensions of these screws are critical for selecting the correct driver size and ensuring proper grip. Key metrics include:
The DIN 7504 K standard covers a specific range of thread sizes and head dimensions to ensure mechanical reliability. 1. Dimensional Overview
The standard specifies the requirements for self-drilling tapping screws with a hexagonal head and an integrated flange (stamped washer) . Often referred to as "Tek screws," these fasteners are engineered to drill, tap, and fasten in a single operation, eliminating the need for pre-drilled pilot holes in metal substrates.
Common sizes include ST 3.5, ST 4.2, ST 4.8, ST 5.5, and ST 6.3.
Understanding the DIN 7504 K Standard: Specifications and Technical Data
This determines the socket or wrench size needed. For example, ST 4.8 and ST 5.5 typically use an 8mm driver, while ST 6.3 uses a 10mm driver.
While the German DIN standard remains widely used, it has been largely superseded by the international equivalent, . Technical Specifications and Dimensions
The integrated flange provides a larger bearing surface to distribute the load. Thread Size Width Across Flats (s) Head Height (k max) Washer Diameter (dk max) ST 3.5 ST 4.2 ST 4.8 ST 5.5 ST 6.3 Data compiled from various technical datasheets. 2. Drilling Capacity
