Unified thread size and \u003cstrong\u003e40\u003c\/strong\u003e indicates that the thread has 40 threads per inch. \u003cstrong\u003eUNF\u003c\/strong\u003e means Unified National Fine. Fine-pitch threads have more threads over a given length than their corresponding coarse-thread versions and should always be matched with the correct UNF component or specified thread.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003cdiv class=\"info-products\"\u003e\r\n\u003ch3\u003eWhat does tolerance class 2A mean?\u003c\/h3\u003e\r\n\u003cp\u003eThe \u003cstrong\u003e2A\u003c\/strong\u003e designation identifies the external-thread tolerance class specified for this die. In Unified thread terminology, the letter \u003cstrong\u003eA\u003c\/strong\u003e denotes an external thread, while Class 2 represents the commonly specified general-purpose fit. The mating internal thread must be selected according to the requirements of the application.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003cdiv class=\"info-products\"\u003e\r\n\u003ch3\u003e60° Unified thread profile\u003c\/h3\u003e\r\n\u003cp\u003eUNF threads use a symmetrical \u003cstrong\u003e60° thread angle\u003c\/strong\u003e.
