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

[Ken K6MR]

Something must have changed recently: I have purchased 30 sets of bolts for 25G from Hill Radio within the last year or so and all worked well. The bolts I just checked are a mixture of JH and JDF markings.

One question I have not seen here: have you put a torque wrench on the bolt/nut combination to determine what the tightening torque actually is?  Did Rohn give you any clue as to what the proper torque should be?

Rohn says they’ve not changed the design of the bolts in “some time” and indeed it is because of the need to “meet standards”. THEY say they probably will remove the galvanizing!! So they’re aware apparently of the fact that their design will reduce the life of the bolt itself! On the first ‘set’ (leg set) I opened, and by the way these appear to be Chinese made as they have a “JDF” marking on the top which a Google search says is a Chinese metal fastener maker, (they are marked as Grade 5 also), I could not turn the nut past the point when the dimples met the thread of the bolt.
