    • Yep. It’s a hammer wrench. The high brows may call it something else but tell a millwright or an iron worker you need a hammer wrench and this what you get. Used in same enviroment as a spud wrench. Made my own hammers out of old 4lb shop hammer and a bull pin. Handy for assembling booms in conventional motor cranes.

    • yup. used to know a guy who worked on big ass gas engines
      the size of a city block. he worked for the gas company.
      L shaped engine. the smaller pistons where the upright ones
      and the sideways ones where for pumping the gas.
      he had a whole set of them. up to like 2-3 inches.
      he also tried to get me a job with them too, but I was the wrong color to be hired then. early 1970’s

  1. Used in pipeline work if you have flange connection that you can’t get a torque wrench on these are used to get the flanges tight. Winging it…….mostly.

  2. We have a great collection of slugging wrenches that we got at a government auction when the Charleston Navy Base was closed down. They are perfect for removing or installing prop nuts.

  3. Its proper name is hammer wrench. Went to the tool crib and asked for the particular size needed and a sledge hammer. Head down to the vessel we were assigned to unbolt and open up and proceeded. Used the things my entire career and they were never called anything else but hammer wrenches. You tell me what the proper name is and I’ll consider it a good day for having learned something new.

      • Yep I saw that with Elmos post below. I learned something new today. A good day. In my entire 42 years working in the heavy construction and maintenance industry on refineries or blast furnaces for example, we always called them hammer wrenches. Nobody went to the crib to ask for a 12 point offset striking facebox wrench, 1 and a half inch. Tool crib guy would look at you cross eyed in all likelihood. Lol.

        • Steve, When I found it I was mildly surprised at it’s official name, I too called it a hammer wrench or slugging wrench.

  4. Wow! There’s a tool for that? You mean I don’t have to beat the shit out of my everyday spanners as I’ve been doing for sixty years? Amazing . . .

  5. But, but officer it’s just a wrench. And it slipped off the bolt when it hit that guy in the head who was trying to carjack me.

  6. Hammer wrenches are used for removing torqued bolts or nuts. Never for ‘pulling up’ unless you are measuring bolt stretch and not using a preset torque wrench.

    Electric and pneumatic impact wrenches have mostly replaced these.

  7. Huh, and here I’ve just been banging on my regular box ends without realizing I could be spending a bunch more money to buy some special ones to bang on. Silly me, who do I make the check out to?

  8. We still use them. We have 4 identical power boilers at work were one connection is in a bad spot so you cant use an impact gun or most of the torque wrenches so we use one of those to undo the bolts.

    Each boiler is 3 stories tall, so not small.

  9. Flogging Wrench in the southern hemisphere.

    I think Micheal Jackson wrote a song about one…

  10. It is used to place the box-end of the wrench over the nut, and the other end is suitable to weld a large piece of chain on it, then wrap the chain around the one-foot diameter concrete door guard before moving the trailer in order to loosen the fastener.
    Then walk into the shop and inform me the fastener is still tight, the concrete pillar did not win the fight and the pad in front of the shop is torn up.
    Retrieve another wrench of suitable capacity, strike once with a twenty-pound hammer – fastener is loose for disassembly.
    Yes. At the shop I was working at. Not all fish in the aquarium can be sharks.
