They have lots of information in them so you'll have to surf around a bit. Sorry I couldn't get a specific link for you. --Scott Upvote 0 Downvote

Feb 19, 2001 #4 Guest Try VDI2330 (German bolted joint standard)or the book by J Bickford ' An introduction to the design and behaviour of bolted joints' From experience the COF of a lightly oiled phosphate coated bolt is around 0.17. But don't quote me on this. Good luck Upvote 0 Downvote
