Sl.No. Synosis Points
1 This document specifies the characteristics of hexagon regular nuts (style 1), in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.
2 The major changes in this revision are as follows: a) Nuts with D < M5 and D > M39 (with mmin < 0.8D not conforming to IS 1367 (Part 6) nor to IS 1367 Part (14/Sec 2) have been shifted to informative Annex A; reference to ISO/TR 16224 for appropriate nut design has been added; b) M7 has been added; c) Values of cmax for sizes M1.6 to M2.5 have been amended in accordance with IS 1367 (Part 2); d) Dimensions of da,max, dw,min and mw,min have been specified with two decimal places; e) Dimensions of dw,min for sizes D ≤ M5 has been changed from smin – IT16 to smin – IT15 in order to have a larger bearing surface area and thus less contact pressure; f) For steel nuts, quenching and tempering condition has been specified in accordance with IS 1367 (Part 6), and property classes 5 and 12 have been added; g) For stainless steel nuts, grades D4 and D6 and property class 80 have been added; h) Non-ferrous metal nuts have been deleted (as a consequence of the withdrawal of ISO
