Windshield Bolt Help
Windshield Bolt Help
Got in my new National Cycle VStream windshield today. A little upset because they sent me the clear rather than the light tint I ordered so it's going back to swap out, but that's another story. My issue is that this windshield seems to be a little thicker than the wind splitter it's replacing and with my windshield bags it seems I need longer batwing windshield bolts. Can anyone provide a part number or the bolt's dimensions so I can find the proper size bolt in just a longer length? Thanks.

1/4-20 is the correct diameter and pitch. I have a National Cycle shield and the extra thickness is only about .050" or one thread of a 20 pitch thread. The stock bolts work fine for me but I have no windshield bags.
I'm assuming that the winshield bags must also attach in the gap for the windshield. If that's the case I would measure the thickness of the bags, add .050 for the winshield, and get a bolt close to that much longer than stock. Probably somewhere around 9/16" or 5/8" long.
Be careful. If you go too long you'll bottom out and either pull out the brass inserts or f up your inner fairing. I think 3/4" length would probably be too long. Finding bolts in 1/16 or 1/8 inch length increments may be an issue (I'm sure you can get them somewhere but they may not be an in-stock item). If that's the case, get longer ones and cut them to length.

Thanks for all the info everyone; especially the link to depss. I was able to buy 5/8 and 3/4 length 1/4X20 polished allen head bolts for less than $10. Bought both lengths at that price just in case the 5/8 isn't long enough. Pretty sure they will be but didn't think I would find that length. Thanks again all.

I recommended the 3/4" length because thats what I sell with the the Fast Aire Chrome & Black trims. If you add a thicker windshield and a set of windshield bags, it ends up close to the same thickness as the trim.
I have checked the 3/4" w/ washers on my 07 and there are no issues with a stock 1/8" windshield with no bags.
Also, you should always use washers under the windshield screw heads or the screw heads will dig into the painted fairing... it leaves a nasty mark.
