It is highly unlikely that you are dealing with a left hand pipe thread. However,sometimes you can get first motion by tightening first. I'm assuming you are dealing with a 1/4 pipe plug as that is what most of them are. In which case you don't have much metal work work with. If you will file the end flat and start by drilling a 1/8 inch hole as close to center as possible and then slowly increase the size in 1/64 increments (this is the standard increment for a good drill index) and watching after each drilling for the first sign of threads you will be able to get to the point where you can pick the remaining threads of the plug out without damaging the radiator. finally chase with a pipe tap and you will be home free.

Frank Ruggiero wrote:wait, are you saying its possible I could be actually tightening it? Its an American radiator, and I am trying to loosen it by turning it counter clockwise. Could it be possible to loosen it by turning it Clockwise? I thought that would only make sense when the screw is holding on some type of wheel that spins counter clockwise...

hmmm..is it a left hand threaded bolt?
But another idea is to drill two holes about an inch apart ifthere is room..then put two bolts or steel rods into thoseholes and use an strap wrench or visegrip pliers onthose two items grabbing them and attempting to turnthe plug via that setup...rube-goldberg I know....but weare down to little remaining choices.

Frank..Not if you are able to tighten the bolt, lockwasher and
nut combo tighter than the plug....especially after the liquid
wrench treatment...

Jerry,
What would I actually need to put the backwards threaded bolt in? I reverse drill with a special bit?
thanks for your help.

Thanks for the reply. This is an interesting approach.
But let's say I drill it, thread it and put a screw a bolt into it. Once I tighten it, and then turn the bolt counter clockwise to loose it, won't the new bolt just unscrew leaving the plug in place?

Be sure to soak plug in liquid wrench as well...

The radiator is cast iron and the plug is in all probability steel, so if you drill the plug it will probably not crumble. If you can use a torch to apply heat to the cast causing it to expand and then use penetrating oil you can get it loose but it will take patience. Once you drill the plug you are committed to either removal or tapping, and will almost certainly damage the threads. Depending on how long the radiator has been out of service there is also a good chance that all of the paper gaskets have dried out and that it will leak.

Do you think it is feasible to drill it out? I just can't get it to budge. If I drilled through it, would the outside of the screw crumble around the center?
I don't want to ruin the threads because I need to screw a valve in where the hex screw is.
I don't even understand why they plug it up. It is so frustrating.

Try tapping on the end of the plug as you apply pressure with the wrench. It sometimes works to try tightening and then loosening until the rust bond is broken. If you can build a clay dam around the plug and fill with turpentine you might be able to get it loose after it soaks for a day or two.

Hi Plumbers.
Can anyone advise? I'm trying to install a new freestanding radiator. I have an issue. I am trying to remove the plug that has been inserted where I wish to place my air intake valve. The radiator was delivered with the plug inserted and I am having no luck removing it. I am afraid I will strip it. I'm trying liquid wrench and no luck.
Has anybody ever had this issue. It's so frustrating. Will this need to be drilled out?
Thanks for your help.

Hi Ed. Thanks for contacting me. I intend to try the torch on Saturday. My work schedule is so intense, I just cant get to it during the week.
I am hoping I will have that plug out, either by torch or by the easy out... (I hope)
