self Locking Nuts!
(OP)
Hello,
Does any one know any MS part numbers for "Non-Self locking nuts". There always seems to be only self locking nuts with or without dry film lubricant.
Like now I want MS21075L06, but I was only able to find this with a self locking feature. I would really appreciate if any one knew the number for without the self locking feature in same or similar sizes. Spoken to suppliers, done searches and found nothing.
Thanks,
Varoon

Maybe the OP is using plate-nuts for an application that is frequently opened, so the threaded features degrade over numerous repeated fastening operations.
If that's the case, may I suggest 1/4 turn fasteners for consideration? These are meant for repeated open-close operations though they will wear out in time, too. They are strictly non-structural fasteners, mind you, and may not be appropriate for whatever you are working on.

monkeydog - NASM14179 first size is 10, but I need 6-32 and 4-40.
Yes Sparweb. It is not a load critical application. The plates are opened very often and it is quite annoying when the self lock feature has no more material to hold it in place. I had a look at few 1/4 turn fasteners.
Two things - 1. It is too big I was looking more about the size of 15mm L x 10mm W x 5mm H.
2. How does it hold to my part? MS21075L06 is riveted to my part and I use the the threads or the locking feature to connect another piece (using 6-32 and 4-40 screws). I do not want to tap directly in my Aluminium part. I would also prefer a floating threaded nut or a threaded nut which is just sitting there and a screw can be used to hold together (not necessarily MS). The hole depths are also different at different locations - with a screw I could just get a long screw and it would work everywhere. How does the stud perform this function. Please do correct me if I am wrong.
Just for this time I can get away without an MS part as what I am doing wont leave our workshop. But still I would like to know if any one have heard about "Non-self" locking features with MS numbers?
Thanks for your responses.

Virtually all plain nuts have relatively low tensile strength.
NO aerospace nutplates [NP] that I am aware of are available without self-locking capability.
You are also asking for a reduced rivet spacing NP [MS21075 has reduced rivet spacing].
Perhaps what You really need is something like a Rivenut [NAS1329, NAS1330] with free-running threads or a threaded insert [NSL helical coil, etc].
SPS has various nut retainer that might be adapted for Your purpose: sheet metal retainer installs like a nutplate, while "capturing" a standard nut [may not come in small-enough sizes for Your purpose]. http://www.spstech.com/aero/fastenerfinder/browseS... Lug 12PT

Non-locking hex nuts are few... but available [AN310, AN315, AN316, AN320, NAS509, etc].
Var10 is looking for NUTPLATES that are NSL.
I think he is best-off looking at quick-turn structural panel fasteners.

RE: self Locking Nuts!
Reason behind why I didn't want to use helicoil was it will consume more time installing them than when they are in action and each part in average has around 8 holes. So labour will make it less worth.
RE: self Locking Nuts!
Other than aerospace do any industries use nut plates or floating anchor nuts
Ok here are a few and you are most likely to be in one of them, Electronics, cabinet and chassis industry. Automobile industry, Food packaging industry, medical device industry, oilfield industry, In fact just about any industry that has a need to quickly remove an access panel or component from a non machined component , then replace it just as quickly.
