I've stopped into a couple of big box stores as well as our local parts purveyor looking for the ever popular 1/2" x 9/16" open end wrench. All they stock are combination wrenches. If you have to separate two parts held together with a 5/16" bolt and nut, you'd need two 1/2" combination wrenches. If you have those pieces held by 3/8" fasteners, you'd need two 9/16" combination wrenches. Fortunately, I started buying tools in 1957.
