Din 7505 Standard Pdf Better Jun 2026

DIN 7505, officially titled "Thread-forming screws for metric ISO thread" ( Gewindeformschrauben für metrische ISO-Gewinde ), is a German Institute for Standardization (DIN) standard that defines the dimensions, properties, and performance requirements for self-tapping screws designed to form threads in ductile metals.

Thread-forming screws create a continuous, residual radial pressure along the entire thread flank. This “prevailing torque” makes them naturally resistant to loosening under vibration, often replacing the need for chemical threadlockers or locking washers. din 7505 standard pdf
