Making nuts stiffer to undo

[transatlantic]

I have a thread with a custom wing nut type thing that rotates too freely. I want the wing nut to only rotate when a fair bit of finger pressure is applied, like a nylon nut. So thought I'd look for some compound to run over the thread. It looks like loctite blue may do what I want. Can anyone tell me if it will hold up with lots of use? This thing is used daily, so am looking for something that will retain it's hold.

could you put a bit of plumbing tape on thread?
cheap and easy to replace

You're probably wear through the Loctite after a while. What is the wing nut made of? Is it big enough that you could drill and tap a snug hole for a nylon screw that would bind on the threads a little? It would be adjustable if needed.

It's quite a fine thread, about M6, too fine for PTFE tape I think

I don't want to change anything if I can.

A thin threaded 'locking ring' to butt up against it maybe?

Slotted nut?

 

[sunnybob]

use a sharp centre punch and hammer a "ding" in each side of the nut at the wing nut end, pushing the metal into the thread. That will give friction. I think you want to undo and do often? if so, start with a small ding and re-ding it untill you have the friction you need.

Oil the thread and then dip it in sawdust. Screw the wingnut back and forth to force the sawdust down into the thread.

That method has worked well on the old vice I am cleaning up 8)

 

[no idea]

Squeeze the threaded part of the wing nut slightly in a vice until you get the required resistance on the thread.

Thanks for the suggestions guys!

Why wouldn't you want a vice to work as smoothly as possible?

I routinely clean and lubricate thread, nut and slides.

Hello,

Anything wrong with a spring washer? Designed precisely to prevent nuts coming loose until you want them to.?

Mike.

And if a conventional spring washer is too visible, a crinkle washer. Both available via eBay in small quantities, often 99p delivered.

No I was joking

I am cleaning up an old vice I bought on ebay and the thread is caked with old oil and sawdust, making it harder to turn.

So old oil and sawdust works well to impede the free turning on the thread which is what the op needs.
