Thumb screws and wing screws, recognized as American National Stand

32、ard, are included in ASME B18.6.8. The inclusion of dimensional data in this Standard is not intended to imply that all the products described are stock production sizes. Purchasers should consult with suppliers concerning availability of products. 1.2 Comparison With ISO Standards There are no ISO

33、standards at this time. 1.3 Dimensions All dimensions are in inch units. When specifying normal sizes, decimal zeros in the fourth place shall be omitted. 1.4 Terminology For definitions of terms, other than those defined below, relating to fasteners or components thereof used in this Standard, see

The wing nuts covered by this Standard are classified, first, by type, on the basis of the method of manufacture; and second, by style, on the basis of design characteristics. They consist of the following:

35、 Type A: cold forged or cold formed solid nuts having wings of moderate height. In some sizes, they are pro- duced in regular, light, and heavy series to best suit the requirements of specific applications. Dimensions are given in Table 1. Type B: hot forged solid nuts available in two wing styles:

36、Style 1, having wings of moderate height; and Style 2, having high wings. Dimensions are given in Table 2 and Table 3, respectively. Type C: die cast solid nuts and are available in three wing styles: Style 1, having wings of moderate height; Style 2, having low wings; and Style 3, having high wings

37、. In some sizes, the Style 1 nuts are produced in regular and heavy series to best suit the requirements of specific applications. Dimensions are given in Tables 4, 5, and 6 for the respective styles. Type D: stamped sheet metal nuts and are available in three styles: Style 1, having wings of modera

38、te height; Style 2, having low wings; and Style 3, having wings of 1 moderate height and a larger bearing surface. In some sizes, Style 2 and Style 3 nuts are produced in regular, light, and heavy series to best suit the requirements of specific applications. Dimensions are given in Tables 7, 8, and

39、 9 for the respective styles. 1.5 Referenced Documents ASME B1.1, Unified Inch Screw Threads (UN and UNR Thread Form) ASME B1.3, Screw Thread Gaging Systems for Dimensional Acceptability Inch and Metric Screw Threads (UN, UNR, UNJ, M, and MJ) ASME B18.12, Glossary of Terms for Mechanical Fasteners A

The

42、bearing surface shall be free from burrs, fins, and protruding surface irregularities. 2.3 Options Options, where specified, shall be at the discretion of the manufacturer, unless otherwise agreed upon by the manufacturer and the user. 2.4 Threads Threads shall be in conformance with ASME B1.1, Clas

43、s 2B, for all types of wing nuts except Type D, which shall be Class 2B with a modified minor diameter. Becauseofthemethodofmanufacture,theminordiame- ter of the thread in Type D nuts may be larger than the Class 2B maximum size, but in no case shall the minor diameter exceed the minimum pitch diame
