3、9:2005-09 2 Foreword This standard has been prepared by Technical Committee FMV-AA 3.12.2 Spannschlsser of the Normenausschuss Mechanische Verbindungselemente (Fasteners Standards Committee). The revision of this standard was considered necessary since the proper length of engagement of the connecti
4、ng component could not be easily checked when using turnbuckles of the type specified in the February 1998 edition. However, in order to ensure the safe use of such turnbuckles, particularly in the field of structural bolting, the length of engagement of the connecting component needs to be at least
5、 equal to length t. The control bore on the turnbuckles specified here ensures this. The DIN 4000-2-8.4 tabular layout of article characteristics shall apply to turnbuckles covered in this standard. NOTE Parts of DIN 4000-2 are intended to be superseded by DIN 4000-161 in which case the DIN 4000-161
6、-6 tabular layout of article characteristics will apply to turnbuckles complying with this standard. Amendments This standard differs from DIN 1479:1998-02 as follows: a) Control bores for checking the length of engagement of connecting components have been specified. b) Tolerances for length and wi
7、dth across flats have been specified. c) For M30 turnbuckles, the minimum width across corners has been corrected. d) For the steel used, property class 5 has been specified. e) Hot dip galvanized coatings have been included. f) Non-electrolytically applied zinc flake coatings have been included. g)
8、 The designation of turnbuckles made of austenitic steel has been amended.
