The NAS6606-27 on the right has the standard thread depth which allows extra threaded length for the NAS1804-6 nut or other standard sized nut. Both of these bolts have the same un-threaded shank size, and the same diameter.

Awesome. I understand that these bolts are just the four outboard gear bolts that go through the U803 saddles and I need to torque them to 240 in/lbs but Aircraft Spruce doesn't have either one of them (unless the nut is NAS1804-6N and they add an N to the end, if it's the same one) and that's on backorder until next month. Where did you order them from?

Try Genuine Aircraft Hardware Co.

I ordered them from https://military-fasteners.com. Aircraft Spruce doesn't carry this size and the order person there refused to make special order. Bummer.

Unfortunately, the military-fasterner only sells in a pack of 10 bolts. After I install 4 bolts, I have 6 left. Let me know if you want the rest or a partial. Send me a PM.

Thanks,

Thanks for posting this picture and description. It is a great addition to the thread (ooh! is that a good pun?) to help people get the right bolts.

Thank you very much for the generous offer, yes I'll take 4 sets.

Is there any other difference between the NAS1804-6 and the NAS1804-6N that Aircraft Spruce sells? The only thing I found in the description on Military Fasteners is the N is "non dry film lube"
https://military-fasteners.com/nuts/...uts/NAS1804-6N

while the one without the N says "dry film lube"
https://military-fasteners.com/nuts/...nuts/NAS1804-6

Everything mentioned on this thread is the part model without the N.

This is the one I ordered from ACSpruce

Any if you are using Grove gear, you need a NAS6206-36 bolt to work with the NAS1804-6 nut. I may have some extras if someone needs them.

Please tell me the Grove gear was an option and not part of the kit back in 2007ish !

How do I know if I have a factory gear or a Grove? I just ordered the bolts and nuts everybody said here and now this wrench in the system. I checked the Grove webiste and they don;t show a landing gear for any Van's aircraft. Now I'm really confused. https://www.groveaircraft.com/aircraft.html
