The new CHT Thread Inspection System from The Johnson Gage Co. (www.johnsongage.com) with an extended range of measurement capability was designed for in-process inspection of large-diameter parts.

Available for any UN, UNJ, Buttress, metric, or Acme thread larger than 3.000 in. the new system is available in dedicated, adjustable and extended-range versions. All existing pitch diameter or functional size rolls are interchangeable on the new system.
