2. Trapezoidal thread form - Wikipedia

   en.wikipedia.org/wiki/Trapezoidal_thread_form

   The original trapezoidal thread form, and still probably the one most commonly encountered worldwide, with a 29° thread angle, is the Acme thread form (/ ˈ æ k m iː / AK-mee). The Acme thread was developed in 1894 as a profile well suited to power screws that has various advantages over the square thread , [ note 1 ] which had been the form ...

   en.wikipedia.org/wiki/Screw_thread

   A screw thread is a helical structure used to convert between rotational and linear movement or force. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread.

   The thread angle also has an effect on the strength of the threads; threads with a large angle have a wide root compared with their size and are stronger. Standard types of screw threads: (a) V, (b) American National, (c) British Standard, (d) Square, (e) Acme, (f) Buttress, (g) Knuckle

6. Unified Thread Standard - Wikipedia

   en.wikipedia.org/wiki/Unified_Thread_Standard

   The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries.

8. Thread pitch gauge - Wikipedia

   en.wikipedia.org/wiki/Thread_pitch_gauge

   A thread gauge, [1] also known as a screw gauge [2] or pitch gauge, [3] is used to measure the pitch or lead of a screw thread. Thread pitch gauges are used as a reference tool in determining the pitch of a thread that is on a screw or in a tapped hole. This tool is not used as a precision measuring instrument, rather it allows the user to ...

9. Buttress thread - Wikipedia

   en.wikipedia.org/wiki/Buttress_thread

   In oil field tubing, buttress thread is a pipe thread form designed to provide a tight hydraulic seal. The thread form is similar to that of Acme thread [10] but there are two distinct threaded portions of differing diameters and profiles, the larger having a wedging profile, with a tapered sealing portion in between the larger and smaller diameters.
