| 1 | This Indian Standard specifies the characteristics of slotted set screws with cup point, 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 7436 : 2024. The major changes are as follows: a) For M3, l = 4 mm has been classified as regular standard length with lnom calculated in order to get at least 4 full pitches and short standard lengths lnom have been calculated in order to get at least 2.5 full pitches; b) For stainless steel screw, grades A2 and A4 with hardness classes 12H and 21H have been added; c) Non-ferrous metal screws have been deleted (as a consequence of the withdrawal of ISO 8839); d) For steel fasteners, “plain” has been changed to “as processed” in Table 3; | |
| 3 | In addition, the following changes are there: e) For stainless steel fasteners, “plain” has been changed to “Clean and bright”, and “Passivated” has been added in Table 3; f) The requirement of surface integrity has been added for steel screws in Table 3; g) Specifications for marking and labelling have been added as clause 6 | |
