Since Creo Parametric 2.0 comes by default without fastener or standard parts library most of us had to download/make those by our self. Major problem is that you have to download different part for different standard and size so in the end you end up with a huge pile of files. And every time you start new assembly you have to add those parts in given folder or use the link to the library via search.pro/config.pro. Last few years I`ve made let's say "compressed" fastener library made up of only 3 files/parts. Basicly you have screw,nut and washer part and each one is actually one big family of parts.
So now you can just copy these 3 in working folder and you are done.
Supported standards and dimensions of fasteners are given in PDF file.
All fasteners are given with cosmetic thread by default.
To turn on physical thread resume feature “navoj-physical_thread” in bolts, “fizicki_navoj-physical thread” in nuts.
Hope you find these usefull...
27.06.2017 Update
Added bunch more standards weld bolts-nelson type, threaded rivets, pop rivets etc.(read PDF) and every part has its own placement interface now.
Also, part names are now in English for easier use. Parameters still in Serbian tho.
Still Creo 2.0 and upward compatibile files.
