    Try www.totallystainless.com. They have some high stength 9/16 but I don't remember if they have fine thread.

    ARP has added 1/2" in both fine and coarse thread to their 2011 catalog. Those should hold anything.

    5.5"? What are you trying to go through...that's long as heck. 3" is the longest 9/16-18 I've seen. You can get up to 5" long in 5/8-18 though. http://www.mcmaster.com/#92198a501/=b1viyd

    You might try to find some "ALL THREAD ROD" in 9/16-18 thread. Then have the nuts welded on one end and make them as long as you want............ Another option for you would be to find a metric fine threaded rod of similar diameter...........

    Thanks guy's ! I was kicking around all thread and welding nuts on but really not sure how heat would affect stainless strength at the end of the day . Went to Fastenal and no go , only fine thread in 9/16 up to 4 inch . I thought a few years ago I saw 9/16 fine thread bolts for sale on this site .

    What Metric size= 9/16 in fine thread ?

    9/16 is 14.29 mm. So 14mm would be close.

    14mm = .5512 ths while 9/16" = .5625

    Is that a fine thread ? I found 9/16 x 5.5 in course thread but at the end of day more than likely no more clamping force than fine thread 1/2 when you think about it . Pretty much given up looking , just went to Mc caster car and no fine thread stainless rod , only course thread

    2.0 is course thread in metric. You simply are not going to find fine thread US or metric in that length. The only other option is to have them custom made at a machine shop and at a premium price.
