How to Select a Lock Nut for your Homebuilt Aircraft

[@edstoro3883]

One point that may help all, is: The treads in a fastener do not carry the same loads. The first thread carries almost a third of the load and the next less, until you come up to about thread #7. After that the treads are almost worthless. This really comes in handy when contemplating the load values in a shear nut vs. full load (AN365). Food for thought. Refinements on this statement are most certainly appreciated. Educate us.

At Hi Shear corp., a big supplier of "Nuts and Bolts" for Boeing and Airbus (famous for the Hi-Lok system) their terminology is "Pins and Collars". I worked in maintenance there for 10 years.

Hi sir, Thanks for sharing your knowledge on suitable nuts. Do you have an opinion on the Fujilock nut? It's for a car application. I believe they will fit between the Nyloc and the AN363 on the aspect of not being to though on the threads making them more suitable to be used multiple times? What do you think.

[@everettchester1517]

I have a pterodactyl ascended. Can you fill an order that has bolts, nuts, washers all an fittings? Hope springs eternal.

[@Michael-xo8lw]

outstanding resource!

[@AutomotiveCNC]

What about using a regular nut coupled with Nord-lock washers?

[@govindahirwar8927]

Make some videos on punches tools drawing and there calculation

[@mohammedpilot2335]

Thanks

[@acemaxximus7175]

Lovin' the profile pic btw

[@gnielse]

That was great. Thanks!

[@Ihaveseenthings577]

Good Video...

[@govindahirwar8927]

Can you give me that how can I make the pushes drawing of nut and there calculation

[@kylelaw7210]

Any disadvantages to the MS21042 or applications that it shouldn't be used for?

[@alexvonhoene1391]

They are more expensive than other kinds of locknuts, more damaging to threads than nylocks, and cannot be reused.

Is it ok to use cadmium plating in aircrafts? Rohs don't allow use of Cadmium or is aircraft accpetion

[@edstoro3883]

The cad plating is serving two purposes. First it is for corrosion protection. Second it is a lubricant. Yeah, no kidding. do not think of it as a grease/oil but it does serve a purpose of the inner-outer threads sliding over each other.

[@How2Desmo]

Do MS21042 damage thread the same way as AN363? thanks

[@markthompson8656]

I believe they do. after taking off about a hundred of these on a jet engine some were so loose once I boke the torque I could unscrew them with my fingers. but most I had to use socket wrench all the way off. Mind you these particular bolts have been removed maybe a hundred times. as this engine is one we practice on disassembly on.

[@How2Desmo]

@@markthompson8656 thanks a bunch

[@uppsala7347]

Surprised he didn't talk spring washers.

[@ronjohnson9507]

Never lose your nuts
