RE: Will this work on a moving mechanism?

No, it won't!!!

A mechanical force and random vibrations are much more aggressive than a human thumb.

It will work within its load carrying limitations.

Since the Guy on YouTube didn't state what it's capable of, and you didn't state your loads no one can say if it will work for your application.

RE: Will this work on a moving mechanism?

It looks like that particular one is very lightly built, so I wouldn't have high hopes. The idea may be worthwhile.

There are some quick-release items used on moving equipment.

RE: Will this work on a moving mechanism?

Seems to me that there are a number of issues

> The device is being held essentially by friction, which has a limit threshold, considerably lower than the yield strength of bolt threads
> The device cannot provide compression force, which is often a requirement for bolting two things together
> The device is not readily scaleable and occupies a large volume, i.e., imagine doing that with a #2 screw.
> The form factor requires side access to the mechanism, which not always available, or even remotely desirable.

RE: Will this work on a moving mechanism?

wireshield,

You can work out the acceleration need to disengage your latch. This will define the vibration your screw can handle. You still need to look at accelerations due to impact, such as someone dropping it.

Isn't this just a very lightly built half nut? Wireshield, if you google half nut or split nut you can find plenty of images of these being used on manual lathes.

RE: Will this work on a moving mechanism?

I like it but I like most new stuff. Also I am so old that most of the stuff I use every day was impossible when I was in high school.

Doesn't mean I am wrong all the time.

Maybe equipment that comes apart frequently such as food equipment. I worked for Swanson Foods while in college and a lot of equipment came apart to be cleaned every 2 hours, 4 hours, shift and / or daily. High pressure hoses, steam, boiling caustic, chlorine rinsing, etc. - they were serious about cleanliness. Just an idea.

Maybe also safety straps.

A lot of cutting tools get changed during breaks and a stuck nut can be horribly expensive. Same with break downs anywhere.

Maybe low pressure plumbing requiting frequent cleaning or setup changes.

I thought I saw threads on the bolt. If so then this is more than just a friction hold isn't it?

It would help if you showed some strength demos and gave some verifiable numbers.

RE: Will this work on a moving mechanism?

(OP)
Thank you all for your opinions and ideas. I am going to try using it on moving parts and see how it holds.
