ICS 49.030.30 CCSV20 National Standards of People's Republic of China MJ thread with countersink for aerospace Swimming self-locking nut for double-ear bracket (ISO 12272.1998, Aerospace-Nuts, anchor, self-locking, floating, Released on 2022-12-30 and implemented on 2023-04-01 State Administration for Market Regulation Released by the National Standardization Management Committee forewordThis document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules for Standardization Documents" drafting. This document is modified to adopt ISO 12272.1998 "Aerospace nuts, backing plates, self-locking, swimming, double lugs, with countersunk holes, MJ screws Grain, grade. 900MPa (at ambient temperature)/235°C, 900MPa (at ambient temperature)/315°C and 900MPa (at ambient temperature Down)/425°C Dimensions”. A chapter "Terms and Definitions" has been added to this document. The technical differences between this document and ISO 12272.1998 and their reasons are as follows. --- Deleted ISO 5858 (see Chapter 2 of ISO 12272.1998), the international standard is not commonly used in our country, it should be determined by the user Requirements to adapt to the technical conditions of our country; ---Changed the expression form of the structural diagram (see Figure 1), which is more in line with the drawing habits of the domestic industry; ---Changed the expression method of letters in the structural dimensions (see Figure 1 and Table 1) and the order of letters in the table (see Table 1), which is more in line with the national The labeling habits of the industry. The following editorial changes have been made to this document. --- In order to coordinate with the existing standard, the name of the standard is changed to "Swimming self-locking MJ thread double lug support plate with countersunk head for aerospace Nuts.
