--- Unify the reference screw standards to be GB/T 193, GB/T 9145 (see Chapter
2);
--- Increase the property class of steel and non-ferrous metal screws of “d< 3mm, as
per agreement” (see Table 2);
--- Increase the steel screws non-electrolytically applied zinc flake coating technical
requirements as per GB/T 5267.2 (see Table 2);
--- Increase the stainless steel screws passivation treatment technical requirements
as per GB/T 5267.4 (see Table 2);
--- Increase the non-ferrous metal screws electroplating technical requirements as
per GB/T 5267.1 (see Table 2).
This Standard adopts re-drafting method to modify and use ISO 1207.2011 Slotted
