P controlled root radius on external thread only.

UNJ external thread assembles only with UNJ internal thread. The UNJ thread standard (ASME B5) defines a system of threads for highly stressed applications requiring high fatigue strength. The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada.

It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries. The UNJF -3A adjustable thread gauge is with an extremely small allowance. In stock and ready to ship. Check with brochure table for exact sizes.
