--- GB/T 846 countersunk countersunk head self-tapping screws;
--- GB/T 847 cross recessed countersunk head self-tapping screws;
--- GB/T 2670.1 hexagonal flower-shaped pan head tapping screws;
--- GB/T 2670.2 hexagonal flower-shaped countersunk head self-tapping screws;
--- GB/T 2670.3 hexagonal flower-shaped semi-countersunk head self-tapping screws;
--- GB/T 5282 slotted plate self-tapping screws;

--- GB/T 16824.1 Hex flange self-tapping screws;
--- GB/T 16824.2 Hex flange self tapping screws.
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 5283-1985 "Sinking countersunk head tapping screws", compared with GB/T 5283-1985, the main technical changes
as follows.
--- Increased R type (see Figure 1 and Table 1);
--- Increase the general technical conditions according to GB/T 16938 (see Chapter 2, Table 2);
--- Steel screws, non-treated zinc and non-electrolytic coating technology requirements according to GB/T 5267.2 (see Table 2);
--- Increase the stainless steel screw products and technical requirements (see Table 2);
--- Added "For other technical requirements or surface treatment, by the supply and demand agreement" (see Table 2).
This standard uses redrafted law revision adopted ISO 1482.2011 "Slotted countersunk head self-tapping screws."
Technical differences from ISO 1482.2011 and their causes are as follows.
--- Normative references, with our standard instead of international standards (see Chapter 2), increase the reference GB/T 90.2 (see Table 2) and
GB/T 1237 (see 5.1), in order to meet the basic standards of fasteners.
--- Increase packaging requirements (see Table 2), in line with China's basic standards fasteners.
--- Modify the mark example To simplify the mark example (see 5.2), to comply with the provisions of GB/T 1237.
This standard is proposed by the China Machinery Industry Federation.
This standard by the National Standardization Technical Committee fasteners (SAC/TC85) centralized.
This standard is drafted by. Machine Productivity Promotion Center.
Participated in the drafting of this standard. Machinery Industry General Parts Product Quality Supervision and Testing Center.
This standard by the National Standardization Technical Committee fasteners responsible for the interpretation.
This standard replaces the standards previously issued as.
