ASME B18.2.2, “Nuts for General Applications: Machine Screw Nuts, Hex, Square, Hex Flange, and Coupling Nuts (Inch Series),” has just been updated. The new 2015 Edition is available now from Document Center Inc. It is part of the B18 fastener series published by ASME, the series for defining the nuts, bolts, and other fasteners that are a part of so many products and installations.
What’s in the ASME B18.2.2? The standard covers the complete general and dimensional data for the various types of inch series square and hex nuts. It also has appendices covering gaging of slots in slotted nuts, wrench openings for nuts, and the formulas that are the basis for the dimensional data. It is recognized as an American National Standard and was once known as ANSI B18.2.2.
ASME has been publishing fastener standards since the beginning of the 1900’s and the first standard for Proportions for Machine Screws actually predates the first publication of the Boiler Code. Today there are approximately 70 active standards included in the B18 fastener series.
