Is there such a thing as a nylock 8m wingnut?

[Fanum]

Just what it says really.......


I'm after fitting some to my Vernatechs to make removal easier......I'll have one inside and the rest outside for security (and anti snagging on the inside) but I've never seen any

I don't know for sure, but I doubt it.
Nylocks are supposed to be one time use only, and wing nuts don't really fit the same criteria do they?

 

[Fanum]

OOoo......

Are they??




Bugger.

Aye, in theory. Most people reuse them, and get away with it in most applications, but really they should be thrown away once they are undone. The thread cuts into the nylon, which stops it from coming undone. Next time you use it the nylon is already cut into, so it doesn't "bite" as well.

Many KTM owners find this out when they reuse the nylock nuts holding their rear sprocket in place which then take out their swingarms as they loosen off.

You could try tacking some wings on to a normal nut, but a) it won't look pretty, and b) the heat may bugger the nylon.

They do exist in Imperial ( www.mcmaster.com) & the only source I have for that size & spec is a Chinese manufacturer but minimum production run is 1000...
What about a dab of Locktite blue on a regular metric wing nut....

 

[Fanum]

Hmm possible possible....



Or.....an over the centre lever arrangement that has a nut on it....flip it around the shaft till it's half a thread from tight then flip the lever over to tighten IYSWIM.....

That must exist

I can feel a Dragon's den moment coming on

Center punch the trailing edge of the tread ( one, two or three points) & it will be vibration resistant...

Could try tacking some wings on an oversized washer, then bend the washer to clamp onto the sides of the standard nylock nut, so turning the washer by it's wings turns the nut also.
Gonna be a tad fiddly on something that small tho.

Hmm there must be a simple, elegant and tested fastener for this sort of application.....

1) gotta be easy to use and quick
2) Requires no tools
3) Reliable and fairly strong

Time for some research I think

How about a normal wing nut with a spring washer...

Tried that on a previous set and they worked loose...these boxes spend a fair bit of time overloaded and off road

Must be something there that will do the trick Bill.

They are available in M6 and M10 in the Spaenaur catalog. Surely an M8 would exist.

 

[Rushy]

Can't you somehow use a large diameter bolt and then drill it and use an R clip on a safety wire behind the wingnut?

 

[NeverRodeBefore]

Instead of a wing nut and spring washer, you could try a serrated washer? Might provide slightly more protection?

Now, I haven't seen the actual fitting in place that your trying to work on, but assuming access is not a problem, I would consider bolting it up as tight as you would normally, and then drill through the bolt with a fine drill and through one of the wings on the nut, and then lockwire the two together. The tension on the wire should stop the wing nut rotating back off, and if it did the wire through the bolt would stop it going too far?

 

[shugie]

What about one of those lever thingies like you get on push bike axles? If such can be obtained in the right size.

 

[the civil one]

Compression !

Just what it says really...... (and anti snagging on the inside)

What your really after is a Compression latch !. or Bicycle skewer.
But again , its gonnie snag on the contents , a Consideration.
Hard to beat a secure Fastener.

 

[PIGGLET]

Dunno exactly what your mounting system looks like but what about a knurled handwheel/nut as shown in the picture of the inside of my panniers?
Mine haven't worked loose but if they start to I'm just going to cross drill the bolt to take an R clip against the knurled wheel so stop it moving IYKWIM
On and off in no time.

Quick release is what is being looked for in this application.

As rushy says, drill hole, R clip, with a "strong" spring washer loading it from behind.
In fact you don't need a bolt to drill. Use a button/stud, spring washer and an R clip, and a rubber washer to waterproof the pannier hole. .
