They absolutely do! I spent many hours with a pair of these as a boy running fence on my grandparent's farm.
The Channellocks that no one knows about, but should have are Channellock 410's, the parrot jaw pliers. The parallel curved jaws are great for removing bolts with rounded heads. Smaller than, but just as tenacious as a pipe wrench with even more gripping surface area. They aren't often used, but when I need them there really is no substitute.
