yea I know about the rubber insert... But what I was trying to do was take off lug nuts off of my trailer. The x handle one they supply didn't provide enough torque to take the nut off so I need a 13/16" socket and all I could find was the spark plug one... SOO that is what I used.

But why I asked the question was I needed to tap the socket onto the nut... then press it out and repeat 8 times!! :Lol:


I oculd go measuer it and everything with a caliper but I rather just ask
