Immelman Posted August 27, 2018 Report Share Posted August 27, 2018 Dont get screwed :))) buying a kit with a lot of stuff you don't need. I think youre better off figuring out the specific fasteners youll go through and buying a stock of those. Quote Link to comment Share on other sites More sharing options...

AN- aviation designation? 526? 832 is 8-32 thread size? R6/R8? I.E- whats the difference between these two screws AN507-832-R6/R8 wing inspection panels AN526-832R6/R8 wing inspection panels The best reference is the reference catalog from https://www.gen-aircraft-hardware.com/store.asp . Their website is not the best, but if you look for their printed reference catalog, it's absolutely fantastic. It has charts of all the various fastener shapes and explains the meaning of all the designations, including pictures and diagrams. On top of that, their prices for fasteners are quite good. The catalog is $8, but it is well worth the cost. One caution--their website actually closes on Sundays, presumably for religious reasons. I've never seen a website that does that before...

Designation replaced by MILSPEC, which adds a whole new set of numbers. 832 is 8-32 thread size (actually, #8 diameter, 32 threads per inch) R6/R8 etc. is length in 16ths, so R8 is 8/16 inch, or 1/2 inch long. AN507/526 etc. is the type of screw like pan head, countersunk, etc. The best place to see the different type of screws is just by looking through the Aircraft Spruce and Specialty catalog and do a search for the AN number. Pictures and descriptions pop up nicely. Never seen the specialty catalog. This is incredibly helpful! Quote Link to comment Share on other sites More sharing options...

DualRatedFlyer Posted August 29, 2018 Report Share Posted August 29, 2018 I was able to get the kit parts list to figure out what hardware and qtys are in the F kit. Adding up the prices of the hardware individually comes out to $89 bucks, while the hardware kit comes to $94 (for the F model). Dont think thats a bad deal to get a little hardware kit established in your hanger. 1 Quote Link to comment Share on other sites More sharing options...

Another bonus is that the F is just a stretched E, so there might be a few extra screws loose in there Quote Link to comment Share on other sites More sharing options...

Clarence What about tinnermans? Are there a handful of sizes commonly used? I have noticed when removing sections of my belly, some tinnerman nuts snap on perfectly and completely, others are too long and have been installed in a diagonal fashion to keep them in place (if that makes sense). The are prone to movement when reinstalling the panels. Quote Link to comment Share on other sites More sharing options...

What happens when your on screw number 476 on the belly panel and that sucker falls off. Now I gotta go back 20 screws to get access back in there.

Now I gotta go back 20 screws to get access back in there. I have a one-piece belly, 52 screws. The belly panel is about 7 feet long. Start them all before tightening any. I scatter ~6-7 screws around the belly panel to hold it, then start all of them. Then I push up in the middle, tighten a row all the way across, and work to one end then do the other end. Another benefit is that you have room to fish around with the ice pick to find those bits that try to hide. What style belly panel do you have? Please let us know so that no one else accidentally buys one like it! Quote Link to comment Share on other sites More sharing options...
0TreeLemur Posted January 18, 2022 Report Share Posted January 18, 2022 I've got a few of the No. 10 speed nuts on the belly of our C that are uncooperative and in need of replacement. Looking at the parts manual, I can't for the life of me identify them. Anyone point to the correct part? Is it this one? "U" TYPE NAS395 (A1787-10Z-1) Thx.

M20F-1968 Posted January 18, 2022 Report Share Posted January 18, 2022 Don't buy a screw "kit", buy the individual screws that you need from Aircraft Spruce. Go to Harbor Freight or your favorite cheep tool supplier and buy some storage bins to keep them separated. You will slowly build a collection of hardware that you will need and use.
