Retard here.

If I want to bolt two things together and there's a gap between them, will the nut and bolt loosen over time even if it's initially tightened?

Will this be fine?

>> No.1476577

How is it tightened if there's a gap there?

You could use two nuts and lock them together

>> No.1476578

>>1476574
Shouldnt really be aa gap if it's bolted together bit if youre worried throw some blue loxtite on it or us a a lock nut. Or i guess you coult just use 2 nuts.

If you want it welded together use 2 lock nuts and red loctite

It's for my campervan, the bottom of the van is a piece of plywood and I don't want it moving around when I'm driving, so I'm going to bolt it to the bottom of the van

Is using 2 nuts much stronger? Why?

Thanks

They have to fight each other to get loose. Also, if they are never comming off without a torch beat the fuck out of the threads with a hammer. They may back off but they'll never fall out that eay

Put some nylon spacers or a bunch of washers on the bolt in the gap. How much of a gap do you have?

>> No.1476682

>>1476574
nylock nut or castle nut

He means that, if you want to ensure that they can't fall off (but they can still come loose), mangle the threads so the nuts get stuck if they start coming off.

Or you could do it non-ghetto status and use a cotter pin. (Castellated nut optional.)

Fully cured red Loctite is stronger than steel.

Then how come buildings aren't made of red loctite?

>> No.1476900

if your going to use a loctite product make sure it is compatible with the material of the bolt you are using it on. For instance stainless requires a special primer. there are different formulas for different size fasteners as well

No polymeric adhesive is even remotely as strong as steel. A Locktited fastener can break rather than loosening because the geometry involved may concentrate stress is places other than the bonded surfaces, but that's not the same thing as material strength. With the right setup, you can break steel with any adhesive no matter how weak.

Do you mean to tell me the loctite rep lied to me? >:(

>>1476800
If this were true nobody would use red locktite. This would mean to get the thing lose the locktite would have to pull the threads apart. Why the fuck would you want a single use bolt, have welders for that

Because jet fuel melts it.

Do it the old fashioned way.
Just a single drop of battery acid on the nut.
lock-tite ain't got anything on that.

define tight
use a spacer even if its just a piece of plywood

>gap is unintentional

Finish torquing it down, spazz. Aforementioned loctite, nut, pin etc can all help hold it all together on top of the pressure of the nut via its threads+bolt.

>gap is intentional
Spacer of some sort along the bolt the measure of the gap you wish to preserve. Washers, another nut, various materials/sleeve, etc all work just makes it so you can torque down the bolt+nut properly.

>rust-tite by nature co, patent pending

An older formula to be sure but no less effective for its age.

>> No.1477405

>>1477309
why?

>> No.1477567

use a spacer between them to take up the slack

or a stack of washers, piece of pipe, piece of wood whatever

>> No.1477825

>>1476574
You could fill the gap with washers. That's the easiest.
