Technical regulations and scope of the ANSI\/ASME B18.2.2 standard<\/h2>\n

This standard establishes comprehensive requirements for the geometric parameters and dimensional characteristics of inch-series fasteners: square, hex, and coupling nuts. The document regulates the design features of the products, ensuring their interchangeability and compliance with general-purpose engineering specifications.<\/p>\n

The normative documentation includes reference appendices describing tolerances for calibrated clearances in slotted nuts, requirements for mating holes for fasteners, as well as mathematical formulas for calculating basic dimensions and methods for monitoring the wear of bearing surfaces. In disputed situations during the acceptance of finished products, priority is given to the calculated values obtained based on the provided formulas.<\/p>\n

It is important to note that the presence of a size in this standard does not guarantee its stock availability from all manufacturers. Engineers and supply specialists at EV Group China are advised to pre-coordinate the nomenclature of items available for order with the supplier’s technical department.<\/p>\n

Compliance with international standards<\/h3>\n

For the inch series of fasteners described in ANSI\/ASME B18.2.2, there are no direct equivalents in the ISO metric system of standards.<\/p>\n

Measurement system and tolerances<\/h3>\n

All linear and angular dimensions in the documentation are given in inches, unless otherwise specified in the specification. When choosing design options not strictly regulated, the manufacturer reserves the right to choose the optimal production technology, unless other requirements were previously agreed upon by the customer when placing an order with EV Group China.<\/p>\n

Terminology<\/h3>\n

For the interpretation of special technical terms and definitions not disclosed in the text of this standard, the provisions of ASME B18.12 should be followed.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[110],"class_list":["post-70229","wiki","type-wiki","status-publish","hentry","wiki_category-asme"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70229","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":0,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70229\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=70229"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=70229"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
