Slugging / Striking wrench for square nut

[pharmvet]

In restoring a heavy duty disk harrow it has occured to me that a slugging or striking wrench might me useful to tighten and loosen the axle nuts. The nuts on my disk are square. I looked all over ebay at striking / slugging wrenches (after I finally found the proper name for them) and found many. I realize a machine shop could make one, but they can be had for around $40 so that would definitely be less trouble and possibly cheaper than having one made at a machine shop. The question is, what point wrench would you use for a square nut if a square wrench (boxed of course) could not be found? Also, do you hit these things with regular steel sledge type hammers, or do you use brass hammers?

Check Snap On Tools and Grainger. Strike it with a steel ball peen. Brass with take the blow more and deform.

On construction sites putting things together we used sledge hammers with the handles cut down to about two ft long. Brass gets beat up to quickly. Would it be possible to use some 1/4 or 3/16 steel plate maybe one inch wide and just build up a box by stacking and welding it together. Heat and a pipe wrench with an extension helps with the removal.

Good evening Dr.,


I strongly suggest you forget the beating wrench for your rebuild work.

You can obtain pair of 12 point impact sockets for spline bolts and acheive the same results using a small torque multiplier with a good quality manual ratchet which would much safer and faster for the purpose. The torque multiplier is held by the ground using its long handle for the fulcrum to break the nut.


The torque multiplier will gradually break the nut loose and be a much more controlled method of removing the nut on the harrow.


You may be able to rent a torque multiplier from a tool warehouse but it will come in very handy for wheel nuts on the tractor(s) and wagon tires and forever for flat tire issues.

Do you have an Oxy Acetylene torch? If not , get one.:thumbsup: Invaluable for heating rusted bolts. Or cutting out extremely rusty fasteners.

On the sockets, id pass on the sluggers. Get a proper size impact rated 12 pt. (or 8 pt, 12pt are more common) socket and the most powerful 1/2" gun you can. With a torch to heat the nuts, there isnt much a good 1/2 gun cant remove. If its a very large bolt, you might have to go to a 3/4 gun.

On large sockets, you can cheat and use a quality chrome socket IF you cant find a 12 pt in the proper size. Yes is not recommended, and some will say its not safe. Alot comes down to the wall thickness of the socket. Larger sockets tend to be thicker, so chrome wont flake or the socket wont split. Thin sockets... no way. Snapon has both 8pt and 12pt 1/2" drive impact sockets up to 1.25".]

Leonz,
12 points sockets don't work well on square nuts, as only contact is a little on 4 corners, which quickly round. I have rounded out numerous tight hex (6 point) nuts with 12 point sockets at home and work.

Striking wrenches are usually 2-3 times thicker than normal everyday 12 point wrenches so they have more contact area on the nut flats.
hugs, Brandi

If a socket is needed for space reasons, 8 point do pretty well on square nuts. Snap On can order these.

The 12 point impact grade flank drive sockets are perfect for this using a small torque multiplier to eliminate the use of a cheater bar which will do a lot of damage.

The problem with the striking wrenches is that they will fly off if the socket head is not fully set and in complete contact with the nut or bolt head or if the bolt head or nut is worn.(been there done that even with good bolts)

The 12 point spline head bolts have the same placement as the corresponding 4 sided bolt heads of the same size as the measurement is the diagonal across the head of the nut or bolt head.

I learned long ago a little heat from a propane torch, patience and penetrating oil can do wonders...

I also have some 8 point sockets...

I agree fully. I have two strike wrenches and they both have sent me to the hospital for stitches. I will never willingly use one again if there is another tool that will fit, even if I have to order it and wait on the brown truck.

Okay, I misread the OP. I was thinking of those open end wrenches with the point on the other end, that can be used as a hole aligner or put a cheater pipe on.

I think 12 and 8 point sockets are sized differently for a given bolt then an open end wrench. I have some (almost) square bolts and nuts that take a 15/16 open end wrench. That same bolt takes around a 1 & 1/16 or 1 & 1/8 inch 12 point socket. Just tried them.

The correct point socket for a square nut is a 8 point socket, right?
