Specification for Threading, Gauging and Thread Inspection of Casing, Tubing, and Line Pipe Threads Upstream Segment API SPECIFICATION 5B FIFTEENTH EDITION, APRIL Measure the shank length of the bolt from the bottom of the head (where it meets the shank) to the bottom of the bolt, using a measuring tape to determine its overall length. Since the difference between metric and standard length bolts is very slight, most often, this measurement is done in inches.

Get this from a library. Gauging and measuring screw threads. [National Physical Laboratory (Great Britain). Metrology Division.]. Jan 28,  · The Ring screw gauge has similar principle to a plain ring gauge, except that screw threads are cut on the inner surface of the ring screw gauge.

Ring screw gauge in used to check screw threads on outside of cylindrical objects like bolts and shafts. Likewise, the screw pitch gauge cannot accurately determine the pitch. Measuring threads can be difficult, especially the internal thread. Often, tools are used such as the thread plug gauge for the internal measuring and a thread ring gauge or a thread pitch gauge for the external thread measuring.

thread pitch gauge, also called a threading gauge, pitch gauge, or screw gauge a device used to measure the pitch or lead of screw threads.

vernier height gauge: a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on. A go/no-go gauge refers to an inspection tool used to check a workpiece against its allowed tolerances via a go/no-go test.

Its name is derived from two tests: the check involves the workpiece having to pass one test (go) and fail the other (no-go). ISO sets a standard for threads and gauging.

(a) This Standard presents screw thread gauging systems suitable for determining the acceptability of Unified [UN], UNR [external threads only], UNJ [internal and external threads], M, and MJ screw threads on externally and internally threaded products.

It establishes the criteria for screw thread acceptance when a gauging system is used. The Gagemaker PD and PD Series gauges measure Pitch Diameters of internal, and external threads. The gauges can be preset to a nominal predetermined dimension using gauge blocks, micrometers, or the MIC TRAC gauge setting system.
