Foreword

This part is one of the national standards for the “hexagonal flower-shaped screw” series. The series includes. ---GB/T 2671.1 hexagonal flower-shaped low cylinder head screw; ---GB/T 2671.2 hexagonal flower-shaped cylinder head screws; --- GB/T 2672 hexagonal flower-shaped pan head screw; ---GB/T 2673.1 Hexagonal flower-shaped countersunk head screw; ---GB/T 2673.2 hexagonal flower-shaped high countersunk head screws; ---GB/T 2674 Hexagonal flower-shaped half countersunk head screws. This part is the first part of GB/T 2673. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part replaces GB/T 2673-2007 "hexagonal flower-shaped countersunk head screw", compared with GB/T 2673-2007, the main technical changes as follows. --- Removed M12, M14, M16 and M20 thread size ranges, increased M2, M2.5, M3, M3.5, M4 and M5 thread gauges Scope (see Chapter 1 and Table 1, Chapter 1 and Table 1 of the.2007 edition); ---M5~M10 is specified as a product with shoulder screw (see Table 1, Table 1 of.2007 edition); --- Steel performance grade increased by 8.8 (see Table 2); ---Stainless steel performance grades are changed to. A2-50, A4-50, A2-70 and A4-70 (see Table 2, Table 2 of the.2007 edition); --- For steel screws, increase the technical requirements for hot dip galvanizing according to GB/T 5267.3 (see Table 2); --- For stainless steel screws, increase the passivation treatment technical requirements according to GB/T 5267.4 (see Table 2); --- Delete the provisions for non-ferrous metal screws (see Table 2 of the.2007 edition); --- Increase the surface defects of steel screws (see Table 2); --- Increase the reduced minimum tensile load regulation (see Table 3); --- Increase the signing rules (see Chapter 5). This section uses the redrafting method to modify the ISO 14581.2013 "fastener hexagonal flower-shaped countersunk head screw". The technical differences between this part and ISO 14581.2013 and their reasons are as follows. --- Remove the ISO 14581.2013 regulations "If you need other technical requirements, choose ISO 4759-1."
