I have a metal rod with these threaded female connectors on each side. I'm hoping to cut the rod down a bit to shorten it but still keep the female connector on the side i cut. Is there a way to remove and reinsert this? I'm not sure how it's attached - I got it off amazon as a camera arm.

threaded insert

  • Probably just need to cut tube to length you want. Tread section is probably bonded to tube at/near ends for only an inch or two. Tube might be quite on weak/flimsy side towards centre(almost like a piece of thin tin).

  • If you look straight down that hole, is there a fastener or socket at the bottom? I assume not, but just checking. If not, I expect you will have to use destructive means to get it out.

    thread a bolt into the insert ... gently tap the bolt with a hammer ... it is possible that the insert will get pushed into the tube ... if it does, then push it into the tube as far as the bolt allows and cut off the extra tube length ... repeat until the tube is the desired length

Cut the rod to the desired length. Then get a rotary tool like a Dremel with a cutoff disk. Cut the tubing that holds the insert lengthwise down to the surface of the insert. Make three or four cuts. Then pry the tubing apart with a slotted screwdriver, freeing up the insert. Slightly chamfer the inside edge of the shortened length of tubing and tap/pound the insert into the tubing.


A bit of lateral thinking:

  • Leave the factory inserts at the end of the tube alone.
  • Cut a section out of the center of the tube.
  • Purchase a set of matching threaded inserts and a short length of all-thread with matching threads.
  • Insert a threaded insert into each of the newly cut ends, holding them in place with epoxy.
  • Screw together to make a shorter tube of the desired length.
    • Add epoxy to the threaded rod for a (mostly) permanent installation.
    • Leave loose for a tube that can pack down into an even smaller space for travel.
  • How about cut a section out of the center, then smear a metal rod with 5 minute epoxy and jam it into the open cut end of either side. Push the cut sides together over the rod. Wipe off extra epoxy.

  • That would also work, @Willk, for a permanently shorted and not disassemblable pole.

If you are willing to risk destruction of the item, heat may serve the purpose. As you wish to shorten the tubing, cutting off the threaded portion will prevent the remaining desired length from being damaged.

It's possible the insert is secured with what is often called Loctite™ and more generically called anerobic thread adhesive. The red version is nearly impenetrable once cured; only heat can break it loose. Secure the insert with a suitable bolt secured in a suitably immovable vise or similar. Consider to also add a locking jam nut on the securing bolt; see below.

Applying heat with a heat gun is probably more controllable than using a flame-based heat source. According to the Loctite™ web page, 500 °F / 260 °C is the release temperature. While heating, consider to twist and pull on the short section of tubing which you left in place for this purpose. You could also, prior to heating, drill a pair of holes perpendicular to the axis, beyond the insert, providing for easier twisting and pulling.

Once removed, thorough cleaning is indicated, as you'll want to use red thread locking adhesive for the replacement. You should have noted the approximate temperature at which the paint started to blister and consider that when heating the remaining tubing into which the insert is to be, well, uh, inserted. Place the insert in a freezer until frozen, or use dry ice for even lower temperatures. I don't know how red thread locker will handle the dry ice temperatures. Loctite's ™ web site says cold temperatures will slow curing time, but does not indicate any problems related to low temperature. I would not be surprised if the liquid freezes on contact with metals at dry ice temperatures.

This may be overkill, if the insert is not held by adhesive means. If thermal methods were used, the same method could be used to replace it.

Check also that mechanical crimping is not in evidence. If so, rotary grinding tools are indicated, aka Dremel™.

You already know the insert fits, so it should not take much convincing.

    Think the OP only needs to cut out a section of centre of tube length. Inserts probably only at ends. Problem of over thinking a problem.

  • @Crip659 - I was going to post exactly that but now people will think I am copying you because I will be. How about you put that as an answer along with how to join the 2 ends of the rod back in the middle. I have an idea about that but am going to post it as a comment if you have a different idea.

    @Willk it depends on what the OP wants exactly. Two short tubes with one threaded end or two short tubes with both ends threaded. Both ends threaded will probably require buying two threaded inserts to add to tubes. My thinking is those inserts are only an inch or two in length in cheaper tube. OP might want/need to add solid rod for strength to other end.
