| 1 | This Indian Standard specifies the characteristics of slotted set screws with long dog point for regular standard lengths and with short dog point for short standard lengths, in steel and stainless steel, with metric coarse pitch threads M1,6 to M12 and with product grade A. | |
| 2 | This Indian Standard was first published in 1993 and subsequently revised in 2002 and 2018. The third revision of this standard has been undertaken to align it with ISO 7435 : 2024. The main changes are as follows: a) For short standard lengths, the lengths of the short dog points z have been added in Table 1; b) The following changes have been made in lengths: 1) The lengths for M1.6 (l = 3 mm), M3 (l = 4 mm) and M3.5 (l = 6 mm) have been classified separately as short standard lengths with lnom calculated in order to get at least 2.5 full pitches; and 2) Lengths for M10 (l =16 mm) and M12 (l = 20 mm) have been classified as regular standard lengths with lnom calculated in order to get at least 4 full pitches; c) For stainless steel screws, grades A2 and A4 with hardness classes 12H and 21H have been added; d) Non-ferrous metal screws have been deleted (as a consequence of the withdrawal of ISO 8839); | |
| 3 | In addition, the following changes are there: e) For steel fasteners, “plain” has been changed to “as processed”, and non-electrolytically applied zinc flake coating has been added in Table 3; f) For stainless steel fasteners, “plain” has been changed to “Clean and bright”, and “Passivated” has been added in Table 3; g) The requirement of surface integrity has been added for steel screws in Table 3; and h) Specifications for marking and labelling have been added as clause 6. | |
