Angle wrench? what do you mean? an offset open end? a wobbler open end? I don't have any of those, actually, but I'll buy one if I have to, I want it sealed tight.
Yeah they are open ends but are at a different angle than the normal wrench. If I remember right a standard combination wrench open end is 30 degrees. These have one end that's 15 degrees and the other is 45 degrees. You can get in just about anywhere with them.
