Hex Bolt DIN960
DIN 960 is a German standard partially threaded hex head bolt, most notably characterized by its fine-pitch thread design. Compared to standard coarse-pitch threads, it features a smaller pitch and a finer thread profile.
Products Description
Regarding material and grade, it is typically manufactured from carbon steel, with common performance grades including 8.8 and 10.9, emphasizing high strength. Stainless steel variants such as A2-70 or A4-70 are also available. For surface treatment, carbon steel options include electrogalvanizing, blackening, hot-dip galvanizing, or Dacromet coatings to meet diverse rust prevention and aesthetic requirements.
The core advantage of DIN 960 bolts lies in their fine-pitch threads. This design delivers superior self-locking performance, effectively preventing loosening in vibrating environments while enabling more precise adjustments and tightening. Consequently, they are particularly suited for applications demanding high anti-loosening, sealing, and adjustment accuracy. These bolts find extensive use in critical components such as precision machinery, optical instruments, automotive transmissions, and high-pressure flange connections.
