QUICK-ACTING KNOBS
QUICK-ACTING KNOBS
(OP)
Has anyone here used any of these fast acting knobs from Carr Lane? How reliable are they? Would you be comfortable securing equipment on top of a truck with them?

I have never used one. I have never handled one. I have never hit one with a hammer. I have never poured coffee on one. I have never seen one. That's why I am asking. I am being asked about quick release fasteners, and I can easily and safely implement studs.

Now of course this is all predicated on them remaining tight, so if the service environment has big temperature fluctuations and/or vibrations, then I would say avoid using them. But if that's not going to be an issue, then I think they may be a good solution particularly if being able to quickly and completely remove the knobs is highly desirable.

Prior experience with similar (hard plastic). Please test them first.

Grit, dust, vibration, truckers.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
RE: QUICK-ACTING KNOBS
They do speed up operations where you have to r&r them a lot.
They hold just fine, if you get them oriented correctly before attempting to tighten them.
If they're just a little cocked when you start tightening, they'll slip off.
Maybe if the extended end seated in a counterbore in a tight fitting thick washer, they would tighten more reliably,
but you'd lose time translating them over a couple of extra pitches.
Even with that modification, ...
No way would I use them to secure a load on a truck.

Can you re-engineer your box to include toggle clamps that will catch on a mounted loop/catch that is mounted to the truck? Especially the double-locking style of toggle clamp.

Thanks. My clearance holes are for M6, so drilling studs and using pins is not an option. My original plan was a threaded, knurled knob, large enough to ensure adequate torque. It looks like I will stick with it.

I cannot see the picture here at work. I saw it at home, so I know it is there.
This is an instrument mounted on a platform on the back of a truck, and I don't see how we could work up a snake theme. Do you think a racing stripe would improve the performance of quick release nuts?
