Size Designations
Size is usually determined by dimensions such as across-flats distance (inscribed-hexagon size). In the 19th and early 20th centuries, it was common to define the nominal size of the wrench according to the nominal size of the screw thread that it was meant to be used on. This is seldom if ever done anymore. (The accompanying photo explains visually.)

Famous quotes containing the word size:
“Crotchless trouser allows wearer to show private parts in public. Neoprene-coated nylon pack cloth is stain resistant, water repellent and tickles thighs when walking. Tan-olive shade goes with most fetishes. Adjustable straps attach to belt for good fit and easy up-down. Pant is suitable for fast exposures as well as extended engagements. One size fits all.”
