1/2 - 13 UNC : Basic Thread Dimensions (Pitch, minor & major diameters, depth, lead), Tolerance range for all applicable classes and much more.
23 Φεβ 2024 · The UNC thread chart referenced on the Engineering Toolbox page is a comprehensive table listing the dimensions and specifications for Unified National Coarse (UNC) threads as defined by ANSI/ASME B1.1 standards.
Overview. 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.

ANSI/ ASME INTERNAL Screw Thread Size Chart. All units are in inches. Unified Screw Threads per. ANSI/ASME B1.1-1989 (R2001), R2001) Nomenclature, are used. Acceptability criteria are described in ANSI/ASME B1.3M-1992 (R2001).
Selecting a fastener that can best match these requirements is critical to the overall performance of an application. Type B, type AB and other standard fasteners, with wide flank angles and shallow threads, were designed for use in sheet metal and can not meet the dynamic requirements of plastics.
