Unified Threads (UNC)(UNF)(UNEF)
The Unified Thread Standard (UTS) defines a 60° thread form in Inch dimensions as described in the ASME B1.1 standard.
It is the North American equivalent of the ISO metric thread system.
The UTS serves as the leading standard for bolts, nuts, and a wide variety of other threaded fasteners used in the USA and Canada.
Classes of fit
1A/1B are used where easy assembly is required. 2A/2B are the classes used for the majority of general engineering purposes. 3A/3B apply to threads requiring a closer fit, and are only used when a close accuracy of form and pitch are required.
Dimensions shown are in Inches, if you wish to convert to mm, please use our universal converter.
