We finished out Field Build yesterday, and I’m concerned that once we’ve dissassembled and reassembled it a few times, the various connections made with 1/4-20 hex bolts and Tee-nuts won’t line up, or the Tee-nuts will strip or not catch the thread or whatever.
So… I got some 4 inch long 3/8 LAG BOLTS (screws). So the plan is if we can’t make the existing 1/4-20 hex bolt / Tee nut connection work, we just widen the upper hole to 3/8, then use the existing 5/16 lower hole as a pilot hole for the 3/8 lag bolt.
I think for field building in the future, I’ll probably just substitute lag bolts from the start. 1/4 or 5/16 lag bolts would be fine - in the case above, I had to go up to 3/8 because of the pre-existing 5/16 holes.
