Gate Bolt

[RichardScott]

Hi,

I need some help with a gate bolt. I have a gate which is metal framed but with wooden slats. The gate is held to the metal posts by two bolts, one at the top and one at the bottom creating two hinges. The problem is, as you open and close the gate it slowly undoes the nut at the bottom. As the nut loosens the gate begins to drop until after a week or two of use it has dropped so low the gate won't shut.

Tighten the bolts hard doesn't seem to help, and loosening them off didn't solve the problem either. I wondered whether a washer above the nut and below the bolt head would solve the problem?

Any other suggestions gratefully received

Second nut tightened against the first to lock them standard engineering practice.
Should sort it once and for all

That would work, except the bolt isn't long enough. I may have to look at replacing with longer bolts if that's the best fix.

Cheers

Bit like Jaws "We're gonna need a bigger bolt"
Or a nylock nut this sort of thing.

If you have any spare thread on the bolt?

Any hardware shop will have a locking nut (nyloc) to replace the original

Or just damage the threads on the bolt

Buy a bottle of loctite threadlocker, smear it on the thread then tighten the bolt. You can still undo the bolt with a little force but it wont work itself loose.
