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.

We’ve been asked by a number of clients how to size and build with metal studs a few times. While it’s always good to go with an engineered design there are tables for metal stud framing that can help us size steel framing based on existing data out there.

What Are Standard Sizes for Metal Studs? Metal stud manufacturers are required to stamp the stud size and gauge on each product. For instance, ClarkDietrich labels 6-inch, 16-gauge studs with CD600S162-54 50 KSI. This tells you the stud is 6 inches wide with a 1-5/8 inch (1.62 inch) flange and is 16-ga (54 mils) thick.

Metal Stud Size Chart. Metal studs are available in different widths, depths, and gauge thicknesses. The gauge of the metal and width of the stud determine the lateral and axial load capacity. Different manufacturers fabricate metal studs of similar sizes, plus some with unique characteristics.

ClarkDietrich studs are made in a variety of flange widths to meet different applications. ClarkDietrich iTools - Structural Stud Lookup Tool. Flange Sizes: 1-3/8”, 1-5/8”, 2”, 2-1/2”, 3”. Thickness: 33 mils (20ga), 43 mils (18ga), 54 mils (16ga), 68 mils (14ga) and 97 mils (12ga).
