    • 2021, Richard G. Budynas and J. Keith Nisbett, “Screws, Fasteners, and the Design of Nonpermanent Joints”, in Shigley's Mechanical Engineering Design, eleventh edition in SI units, page 423:
      A multiple-threaded product is one having two or more threads cut beside each other (imagine two or more strings wound side by side around a pencil). Standardized products such as screws, bolts, and nuts all have single threads; a double-threaded screw has a lead equal to twice the pitch, a triple-threaded screw has a lead equal to 3 times the pitch, and so on.
