CORRECTION!  It's a BOX wrench!

I have, or had? a 12" T handle about a foot long, but there us now a socket wrench that ratchets available in the big box stored and many hardware stores. I think the one brand is Cobalt. They seem well made and have a nice finish.

##  agreed.  I use the never seize  made by Loctite corp. Looks like
silver goop. The deluxe version is called marine grade never seize, also
made by Loctite corp.

## Where I had real bad issues with galling was when using .25-20 SS bolts and mating SS NYLOCKS. The slightest nick or ding on either the SS threads of either the bolt threads ..or SS Nut threads and they would seize up asap. The nylock would bind and gall...and thats b4 the nut was even all the way down. IE: tiny air gap. Then I had to cut the bolt off.... behind the SS nylock... on the inboard side, where the gap lay...with a 1 inch cut off wheel on a dremel. SS bolts + regular SS nuts.... IE : non nylocks
have given me zero issues.

## My fix for SS these days..is to..chase the threads with a die 1st..on the bolt. And ditto with a tap into the SS nylock threads. Once both threads are cleaned up, then apply the never seize goop.... onto both bolt threads and Nylock nut threads. End of problem.

## absolute bitch to try and run a die on a SS U bolt though. The ..T handle of the die gets in the way, since the U bolt is parallel threads ! Best I can come up with is to ditch the T handle..and
just screw the die onto the SS  bolt on both legs of the SS U bolts.

## When buying or storing SS hardware, keep them separated, dont allow the SS threads to get bashed about. If down at your local hard ware store, examine the SS hardware that u pull out of the bins.... b4 you buy anything. Avoid dinged up threads like the plague, or any minor, visible imperfections.

## You really should not have to be mucking about with SS hardware up a tower in a lot of cases. The SS hardware, like .25-20, for boom splices.... and say 10-24 or 10-32 or 8-32 SS hardware + SS nylocks..like if used for ele joint splices.... is all done on the ground..in advance.

## If using the double plate scheme... aka.. easy on mount, like F12 uses to mount a boom to the mast, I would use galvanized G-5 hardware to mate the 2 x al plates, which requires a total of 5 x bolts + 5 nuts.

## I use the DXE jumbo super mast clamps to hold the Vert plate to the mast...and those use armor plated G8 bolts and nuts etc. Even on the galvanized hardware, I use either never seize.... or penetrox on the threads.
