Table of Contents show Metrology is a significant department of Mechanical engineering that deals with the measurement of a workpiece. Thread plug gages are used to check tolerances of threaded parts according to a certain specification. Metrology is oftentimes called the science of measurement that depends upon two significant factors. A ring gauge, or ring gage, is a cylindrical ring of a thermally stable material, often steel, whose inside diameter is finished to gauge tolerance and is used for checking the external diameter of a cylindrical object. We also manufacture other related products such as the ground lock nut, ground screw, etc. View Datasheets by Spec.

Thread Ring Gages also referred to as thread ring gauges are used to check the outside major diameter and pitch diameter limits on threaded parts. When this ring gage is turned hand-tight onto the external pipe thread the small end faces of each must be flush within a tolerance of plus or minus one turn. externally threaded part. 5.3.4.2. Threaded ring gages cannot and will not detect an undersized product thread’s major diameter. API working plug and API thread ring gages are manufactured to American Petroleum Institute (A.P.I) specifications and are used as the benchmark for calibration by the National Institute of Standards and Technology (NIST). Full gauge specification for incoming and subsequent inspections purposes .....11 3. A thread ring gauge is designed to check the correctness of the thread, to include thread depth and pitch diameter (to the given pitch / TPI). Thread Ring Gauges. Thread gages are used to ensure the assembly of mating parts. 0.5 - 14 20, 16, 12, 10, 8, 6, 5, Thread Ring Gauges.
