I am a fabrication engineer based on the Gold Coast. I specialize in Bobcat & Earth moving equipment I undo hydraulic cylinders all the time. People come to me if they cant undo them. I came across Macht Tools and Steve a few months ago. Stilton's used to be my go to tool but not now!
With stilton's you're only using half the tool to get the head on and as soon as you put the pressure on the stilton's tend to screw off to one side and come off and damage the head. where Macht wrench doesn't because its contact in three places, it's holding it a lot better. The top head square and because of that configuration, It wants to stay on the head rather than leave it. They don't tend to slip off and they lock on straight away with no adjusting required
They are a brilliant tool. I wouldn't tell people about them if they did not impress me. They are my go to tool without doubt on a daily basis
