maddmaxx1949 Posted July 6, 2021 Report Share Posted July 6, 2021 Bit of a stupid question here but I'm curious. I had nuts that came off my fluid drive coupling ('49 coronet) and I can't for the life of me find the same ones anywhere. They measure 7/16-20 thread, 5/8" width/wrench size and the hard to find part is that they are 3/8" thick. Any word on where to find these? I've already been through McmasterCarr and Grainger. The ones on my '51 were 19/32 and I don't want to mix and match. Followup question, do most of you just use a standard 7/16-20 , 11/16" nut?

Solution 61spit Posted July 6, 2021 Solution Report Share Posted July 6, 2021 You might try Aircraft Spruce & Specialty Co. for aviation type hardware. There are thin check nuts or hex nuts - low height. I don't know how thick they are but they are thinner than a standard nut. www.aircraftspruce.com 1 1 Quote Link to comment Share on other sites More sharing options...
maddmaxx1949 Posted July 6, 2021 Author Report Share Posted July 6, 2021 (edited) Wow this is why I love this forum. Found them in less than 5 minutes Thanks 61spit! Edit: for those looking the nut number is AN315-7 plain hex nut Edited July 6, 2021 by maddmaxx1949 part no. 1 Quote Link to comment Share on other sites More sharing options...
Doug&Deb Posted July 6, 2021 Report Share Posted July 6, 2021 They are also called jam nuts for applications where you need to double nut something. Quote Link to comment Share on other sites More sharing options...
maddmaxx1949 Posted July 6, 2021 Author Report Share Posted July 6, 2021 I did check the options for jam nuts but all I found were either on 1/4" thick or less and/or 11/16" wrench size. I looked a long time, it was a pain lol. Why so much effort for these nuts? I'm sure most people would just throw on a standard size and go but its just the way I am I guess. Got to be a little crazy to work on some of this stuff Quote Link to comment Share on other sites More sharing options...
Kilgore47 Posted July 7, 2021 Report Share Posted July 7, 2021 I went to that aircraft site to check it out. And there on the page when it came up was the cable I needed for the hood release on the 47 P15. 23 bucks. Thanks 61spit. The cable is on order.

61spit Posted July 7, 2021 Report Share Posted July 7, 2021 Glad you found something that will work. Maybe a bit more expensive because it is aircraft approved but if it works and the price is OK then that's all that matters. Quote Link to comment Share on other sites More sharing options...
Sniper Posted July 7, 2021 Report Share Posted July 7, 2021 Nice source for the nuts, now if only we had a similar source for the bolts? Quote Link to comment Share on other sites More sharing options...
maddmaxx1949 Posted July 12, 2021 Author Report Share Posted July 12, 2021 Update: Recieved the nuts and they are the same except ever so slightly thicker maybe 1/32" which is plenty close for my standards. Other than that right on. I didn't end up ordering from the company mentioned above but they should be the same. Quote Link to comment Share on other sites More sharing options...
