Prevailing torque type hexagon regular nuts (with non-metallic insert) with metric fine pitch thread - Property classes 6, 8 and 10
|Publication Date:||15 December 2012|
|ICS Code (Nuts):||21.060.20|
This International Standard specifies the characteristics of prevailing torque type hexagon regular nuts (with non-metallic insert) with metric fine pitch thread with nominal thread diameters, D, from 8 mm up to and including 36 mm, in product grade A for sizes D up to and including 16 mm and product grade B for sizes D above 16 mm, and with property classes 6, 8 and 10.
If other specifications are required, they can be selected from existing International Standards, for example ISO 261, ISO 724, ISO 898-2, ISO 965-2, ISO 2320 and ISO 4759-1.
NOTE 1 The dimensions of the nuts correspond to those given in ISO 8673 plus prevailing torque feature.
NOTE 2 As there is an insufficient nut height due to the fine pitch thread, there is a higher probability of nut thread stripping. Hence, high nuts according to ISO 7041 are preferably used.
