I was trying to remove the oil pan plug nut and found that it was on extremely tightly. I was using a fairly inexpensive socket wrench ( for only the second time ) and couldn't get it to budge. So I took a small hammer and tapped ( really just tapped as I had no clearance to make any kind of serious swing at it ) the socket wrench handle for a little bit to try and loosen up the plug. The plug didn't move, and now the socket wrench no longer moves back and forth.

Should one not ever tap a socket wrench like that with a hammer ( even very lightly ) or is that usually OK and this is just a poor quality ratchet?
