UNEF- 60 Degree Unified National Extra Fine Threads. UNEF Thread Series / UNREF, is applicable where even finer pitches of threads are desirable, as for short lengths of engagement and for thin-walled tubes, nuts, ferrules, or couplings. It is also generally applicable under the conditions stated above for the fine threads.. . .
Forinstance, when a screw or bolt measures 5.9mm, it is called a 6mm thread. There are two common methods to write the thread dimensions. 1.Thread sizes in inches are specified by diameter and threads per inch. For example, in the screw size 10-24, the first digit refers to the thread diameter, the and second digit is threads-per-inch

Thisstatement in B1.1 means that the threads described on a drawing as “Class 2A” are to be inspected using the size limits for Class 2A BEFORE PLATING OR COATING. This means that the Class 2A GO and 2A NOGO limits and gages must be used to inspect and accept the pre-plated or coated threads. After the threaded parts are

Theexternal thread is a 3/8-24 UNF class 2A. They assume that the internal thread must have the same 2A class of fit as the external thread they presently manufacture. Based on this assumption, they contact their gage distributor / manufacturer and order a 3/8-24 UNF 2A plug gage. The only 2A plug gage that exists is a setting plug.
