| 1 | This Indian Standard was first published in 2005. This first revision of has been undertaken to align it with ISO 7434 : 2024. The main changes are as follows: a) The point angle with tolerance of ±2° has been changed to a reference angle of 90° or 120°, without tolerance; b) The values of dt for cone point have been added in Table 1; c) In relation to length: 1) For M1.6, length of 2 mm has been classified as too short (see Table 2); 2) The lengths for M2 (l = 3 mm), M3 (l = 4 mm), M3.5 (l = 5 mm), M4 (l = 5 mm) and M5 (l = 6 mm) have been classified separately as short standard lengths (see footnote in Table 2) with lnom calculated in order to get at least 2.5 full pitches; and 3) Regular standard lengths have been calculated in order to get at least 4 full pitches up to M3.5 and 3 full pitches above M3.5; d) For stainless steel screws, grades A2 and A4 with hardness classes 12H and 21H have been added; e) Non-ferrous metal screws have been deleted (as a consequence of the wi | |
| 2 | In addition, the following changes are there:e) Non-ferrous metal screws have been deleted (as a consequence of the withdrawal of ISO 8839); f) Mechanical properties of steel and stainless-steel screws have been added for d < 1.6 mm (“As agreed”) in Table 3; g) For steel fasteners, “plain” has been modified to “as processed”, and non-electrolytically applied zinc flake coating has been added in Table 3; h) For stainless steel fasteners, “plain” has been changed to “Clean and bright”, and “Passivated” has been added in Table 3; j) The requirement of surface integrity has been added for steel screws in Table 3; and k) Specifications for marking and labelling have been added as Clause 6. | |
| 3 | This Indian Standard specifies the characteristics of slotted set screws with cone point, in steel and stainless steel, with metric coarse pitch threads M1,2 to M12, and with product grade A. | |
