[TowerTalk] Rohn Bolts AND nuts - won't mate

[Wayne Kline]

IMHO  Rohn knows  what they are doing .
 
the "dimpled " locking  nut  are not a new  
 
Use then in  the   HD  Truck industry for  years

 IMH use them and if you feel it my  cause rust a simple can of cold galvanizing  for the win ...

I don't know when they started using locknuts, but for decades they did not use them.  There are thousands of towers installed without locknuts and without problems as a result.

It – the nut, has 3 dimples that Rohn now stamps in to provide a locking mechanism. But its so aggressive that once the dimpled part of the nut – the outside of the nut gets to the bolt you’re done turning at least with the larger bolts. I don’t see how I can turn this without some form of air wrench and then all the galvanizing is going to be stripped off! I managed to get the nuts on the small ones in place – small bolts that is – but it is pretty shiny where the threads are and not sure there’s a great deal of zinc there.

It is used. I bought new Rohn (yes – Rohn) bolts and I’ve never had bolts that were SO tight before. These have a dimple on one side – actually a set of 3. I’m sure it’s a self locking mechanism. You can’t thread them on at all starting with the dimpled face – they won’t go – so I’m pretty sure I’m doing it the right way ... the small bolts went on with lots of effort seeming to strip the galvanizing off the bolt as they went on .. the large ones don’t want to go much more than when the dimple gets on to the bolt.

They also said I’m probably putting them on backwards – which isn’t possible as you can’t even thread them on on the dimple side!]
