Some times nuts are too much seized on screw or head is so much damaged or worn that they cannot be unscrewed with conventionnal wrench or socket.
So last solution is to destroy the nut to loosen the assembly. For this you can try using a saw or an angle grider but you risk to damage the screw and access may be difficult.
Nut splitter is a simple low cost tool that will do this work without above problems.
Working principle is based on a wedge that is pushed by mean of a screw and forces the nut to break.
Use is very simple, just put the nut you want to loosen in the hole of the tool and screw tool until the nut breaks. Do not overtighten to prevent damage to the threads under the nut.
When the screw is broken normaly it can be loosen without effort.
