Am I the only one who doesn't have sockets for square head bolts?
The other day I got into a comical usage of an assortment of wrenches to work a square head nut. Use this wrench and turn, then flip over and turn a little then grab the other wrench and turn some, then back to the first and repeat.  Drop one, bump your head...
Hey it was hot and humid out.

12 point sockets work just fine on them.

Your right Brian... 6 pt are worthless in this application. 12 point should work, but the OLD nuts normally have worn edges and not much to grab.. I normally TRY to use 12 point if i can get one that fits and dont slip.. They make 8 point for the square nuts and pipe plugs. I have a set of them, but you hate to spend much money if your not using them very often..

Like them all, but love the "B"s.

Heat them with a torch first, then toss some  squirtum on them and 12 pt will take them off most of the time.

Heat is the miracle for breaking stuck nuts.  I know about 12pt sockets, don't have enough of them and most of what I get into will round off.
So do you replace with square head hardware to keep original look, or use whatever they got at the store (hex heads). You can go broke and batty looking for original style hardware.  Then even in hex heads, there is common usage in ag equipment of  the "heavy"  hex's, bigger wrench and thicker nut. Is it just me who tries to find the heavy nuts if originally used?
Maybe some day I will relax and be ok with using a nail as a cotter pin, and any nut and bolt that fits and so on.

McMaster Carr is the one shop I buy a lot of odd fasteners from otherwise use Fastenal locally.

My craftsman set came with a full set of 8 point up to 3/4" plus i have a second set that came with the set my wife gave me back in 1981. I dont use them often but when you need one nothing else works. Ive taken down several grain bins that have square nuts. If you dont have a socket you wind up cutting many screws they usual have sloted head screws and square nuts

I just bought this 15/16" square impact socket to remove the square bolts in the steel wheels of my (steel wheeled) B.
I thought the price was reasonable. Lots of Kroil, but I am still torching a bunch of the bolts. Not surprising since they have been run in the dirt for many of their 75+ years." rel="nofollow -

Back when I had the Ford tandem dump truck those inner and outer fasteners for the bud wheels required a square drive socket - ended up with a couple different sizes in impact sockets to take care of the tough square nuts / headed studs . 
 Hub piloted buds are sure easier now

BrianC your talking about just for an example the correct nuts and bolts in the adjustable wide front on a WD45. When I got my 45 next trip to the tractor salvage yard I had to get the correct bolts to replace mine

Brian,  Try Spaenaur in Kitchener. Can order on line. Have everything you can imagine in fasteners including original hood clamps for D series and chrome original style grill clamps for D-21 and hundred series.

Nothing is impossible if it is properly financed

I don't think you're the only one. I didn't even have a socket for square head bolts some time ago. Moreover, I had no socket for other types of screws. When it came time to install the http://" rel="nofollow - decking screws I ordered, I couldn't because I didn't have the right tools. So I had to order the whole set needed to be equipped for such situations in the future. Your solution is just as good, but it is much more convenient and safer to use a socket for bolts. I think so ;) So I recommend you to buy one. It will be helpful.

If it's for rare uses, try one of the universal sockets:" rel="nofollow -

I always found that those things were only good for making a nut into a round piece of steel. Never had any luck with them.

LOL  Yeah, round it off, grab it with a pipe wrench, and problem solved!

Square bolts and nuts made sense at one point in history, and every once-in-a-while, there's circumstances where they're necessary NOW, but the flippin' wrench/bump head/drop wrench routine stinks.  Having the head rounded-off (or in more cases than not, just corroded off) to the state that ANY wrench or socket won't grip, I use one of two tactics:

Hold a 6-point NUT against the head, and apply hot-glue (ER70S is my favorite flavor here) to the bolt head THROUGH the nut, until the nut holds itself on, allow the 'glue' to fully cure, then apply impact socket and electric gun...


Apply enough heat for the offending fastener to develop a little red spot, then pull the magic trigger, and watch the fastener head vanish onto the shop floor, then use a suitable drift punch to drive the remains out...

I used to be young and patient... I guess I'm getting too damned old-and-grumpy for that, eh?LOL

Ha, today it is hot and humid and I needed a HEX thin/jam nut, 3/8-24.
I headed out to find one with full confidence that no store around here would
actually have it. I was right! So aside from square head hardware, now they
don't even stock hex head. The lathe was employed to face down a regular nut. I got lunch out of the trip.
Fastenal left town. I do have a Mcmaster-Carr account, and they do have everything, but the shipping is always a shocker.
And last week my welding tanks went empty while cutting up scrap. Wonder what kind of new pricing they have on welding gases.

Brian, that's the kind of day when we gotta say:

Somedays the dog...
Most days the Hydrant...LOL
