Removing Stuck MTB Pedal

[Skylark]

So I'm sitting with this same issue now, on the right pedal.

 

During hard lock down I had the pedals on the old Scott, transferred them to the Giant when we were allowed out again. I did grease the threads but obviously not so well. Left pedal came off with ease, right pedal has rounded 2 allen keys and a hex socket.

 

After I rounded the first allen key I doubted myself that I was turning it in the correct direction, so I jumped onto the interwebs to confirm.

 

With the second allen key I tried impacting it with a hammer to jolt it loose.

 

Would it be ok to get use the pneumatic guns at work to try and loosen it ?

A pneumatic impact wrench should get it loose.

A pneumatic impact wrench should get it loose.

just chatted to a technician in the workshop who is also a cyclist, he is hesitant to use the pneumatic drill, but he has good quality hex sockets so we are going to try that first.
