Why the hell is this bolt size so hard to find. I only need one. I don't need to spend $25 on shipping and more bolts than I need. Anyone have extras or tell me where good place to buy one?5/16-18 x 7/8"

Yeah, but frequently with Fastenal you can't get just one, but these you can in zinc -- above is chrome.Fastenal...they have everything if it's a bolt...lol

Nylok nuts are a one time use. Besides there dirt cheap why wouldn’t you replace them for peace of mind.I'd be concerned with WHY and HOW it fell out..
Also, remember you can't re-use Nylock nuts forever they need to be replaced after a number of times on and odd the bolt. There are those that believe if it comes off the bolt, replace it with a new one. Not a bad idea inside a closed primary were it could do serious damage at speed.
I was thinking wrong bolt when I read it the first time, and I generally do replace them. I have on occassion reused them when I didn't have a replacement handy. (With a note to self to replace later at earliest opportunity)Nylok nuts are a one time use. Besides there dirt cheap why wouldn’t you replace them for peace of mind.
Yeah drove 20 minutes each way at lunch today to go to a Fastenal. All their locations are supposedly closed to the public now. at Least here. She still looked for me and they still had to be ordered. Those arent the same ones above. Don’t they need to be flat head screw caps? Nylock nuts? I’ll have to read up and see what you guys are talking about.Yeah, but frequently with Fastenal you can't get just one, but these you can in zinc -- above is chrome.
You are correct. All I need is # 65 chain adjust screwJust for clarification Phatnasty I believe your after part # 65 in the diagram below and not part # 22
