Full info on DIN7990 bolts 1

[IJR]

Could a fellow engineer suggest a website or source where I can find full information on DIN7990 bolts?. I have a catalogue showing geometrical properties of this group of bolts, but what I actually want is an original document showing typically manufactured bolt grades(e.g 4.6) and their mechanical properties, eg proof strength, pretension limits etc. Thanks in advance

You can use the following link to search for your desired standard. The site is originally written in Germany but an English version is also available:

Good luck
