Ojiyas manufacture many diverse types of unified thread gauges: Ojiyas UN Thread Plug Gauge – Unified Fixed Pitch Commonly used: With 4, 6, 8, 12, 16, 20, 28 & 32 standard thread per inch. Ojiyas UNC Thread Plug Gauge – Unified Coarse The most used thread type for fasteners, General purpose inch gauging, lower tensile strength materials. Due to the inherent coarse pitch, the thread is deeper than UNF and easier to install without cross threading. Ojiyas UNF Thread Plug Gauge – Unified Fine External thread stronger in tension than coarse thread due to the lesser thread depth compared to UNC and it has finder tension adjustment and tighter tolerance. It is commonly used in the aerospace industry. Ojiyas UNEF Thread Plug Gauge – Unified Extra Fine Finer thread compared to UNF and it is used for incredibly special applications such as tapped in thin wall material and tapped holes material. Ojiyas UNJC & UNJF Thread Plug Gauge Similar thread form with UNC and UNF except that the outer thread has a larger root radius compared to UNC or UNF thread. This results in a larger tensile area and smaller stress concentration.

TECHNICAL SPECIFICATION

TPI (Thread per Inch) on Unified Thread Gauges

In unified thread the thread pitch measurement is count of number of threads per inched along the length of a thread. Generally, thread per inch used in Unified thread while Thread pitch are used in Metric thread.

Unified Thread System

The class for Unified Thread is designated by letter ‘A’ & ‘B’. Thread Plug Gauge is ‘B’ while Thread Ring Gauge is ‘A’. Therefore, tolerance classes 1A,2A and 3A apply to Thread Ring Gauge and Tolerance classes 1B,2B and 3B apply for internal threads. Most commonly used are the Class 2A and 2B.
