How to remove a screw without hex end

How to remove a screw without hex end

How to remove a screw without hex end

(OP)
Hello, does anyone know how to remove the connector in the attached photo without damaging it?

RE: How to remove a screw without hex end

From which end?
How much is exposed?
What materials are involved?
Is access limited?

RE: How to remove a screw without hex end

(OP)
The small end of the aluminum connector is screwed into the board and the remaining whole part is exposed.

RE: How to remove a screw without hex end

How did it get screwed in?  Seems like it couldn't e torqued very much.

RE: How to remove a screw without hex end

the threads on the left side are right hand, a driver threads on to this thread and bottoms out on the flat, thus the small right end threads into board and torqued so that the driver can be removed.

the center  threads are left handed, a driver threads on to this thread on bottoms out on the end flat, thus the small end can be unscrewed

I think byrdj was right about the threads, thanks for your replies my fellow ME.

Clamp some vice-grips on it and turn it.

Oh, you wanted less damage?

Find a female threaded thing that goes on the protruding part, like say a nut. Slit it so it's collapsible. Put it on the protrusion. Grip THAT with Vice-Grips so as to grab the protruding piece w/o damage. Unscrew.  

RE: How to remove a screw without hex end

FreddyZ - I like the slit nut idea.  So obvious I overlooked it.  I could have used this on dozens of things over the years and will probably forget itbefore I need it again.  But what a simple and elegant solution.

RE: How to remove a screw without hex end

FreddyZ...never thought of that!  Excellent for many applications!

RE: How to remove a screw without hex end

Dont forget the other old trick used for removing studs.
  Run two nuts on, jam one back against the other,  turn the part off using the bottom nut.
B.E.

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them.  Old professor

RE: How to remove a screw without hex end


I would use berkshire's method. It has been used for ages to remove studs. No special tools needed.

RE: How to remove a screw without hex end

The two-nut method works fine on steel studs.  

However, on thin-walled, fragile parts like connectors, and on solid but weak parts like copper studs, it may stretch the part to failure between the nuts.  I'm sure I have done so at least once.

FreddyZ's method is so stupidly simple and easy to overlook that they should teach it in engineering school.
