I intend to use these in a Live Steam hobby project. I intend to use them to join one inch high Steel rail sections together.

Always a pleasure to see the folks in West Chicago. They are so helpful and greet everyone with a smile. Thank you for coming to the Midwest. I look forward to the time when you start carrying wood, as I am restoring a 1942 Stinson L-5 Sentinel and a 1945 Percival Proctor - both ground up restorations. Thanks for your assistance.

They lock! True AN hardware to Mil Spec.

Exact size ordered, work perfectly.

These things are the way to go for very secure connections

I write reviews as a hobby. However, its kind of hard to attach a Product Review to a lock-nut. Nevertheless, AircraftSpruce requested my assessment. These appear to be very well-made. While I do not know the country origin of manufacture, Im hoping these are NOT made in China. I think it would be in the best interest of AircraftSpruce to list Made in America whenever it applies. On the admin side, AircraftSpruce efficiently managed my multiple orders. The real test will come over time, both functionally and weather or not AircraftSpruce carpet-bombs me with ads.

These nuts are the nuts.

The AN nuts are priced very good and the shipping options are awesome. I love buying from Aircraft Spruce because of the great products, fast and affordable shipping, and ease of buying small quantities if needed.

I love my nuts!! They worked great!!

order went very smoothly

As advertised and very quick shipping like it always is from Aircraft Spruce. Sherwood

Good stop nut, but not for engine side of the firewall.

How do you review a bolt? I trust Aircraft Spruce to do their due diligence sourcing their hardware so as not to be selling counterfeit parts.

Parts I ordered and previous parts arrived and were exactly what I ordered and function perfectly- I needed a new Vacuum pump for my Cessna150 and is working perfectly. Thx

Great , exactly what I wanted and shipped the way I asked

Best nuts ever.

just as described

I always count on Aircraft Spruce!

its a nut..... it works for me

good prize

Happy with the product but shipping And handling seems too expensive

Elastic (keeper) nuts are just right. Minor problem — I ordered 8, received 7. Good thing I was only using 4, the other 4 were for backup.

It is hard to get excited over stop nuts but they appear to come in bags of 25. This is not mentioned as best I can see. I think this should be stated as when making an order up for stock, whether is is 20, 25 or 30 does not matter much. I much appreciate that one can purchase the nuts one at a time, but knowing that they can come in bags of 25 each has merit.
