Point;
--- GB/T 16824.1 Hexagon Washer Head Tapping Screws;
--- GB/T 16824.2 Hexagon Flange Head Tapping Screws.
This Part belongs to Part 1 of GB/T 16824.
This Part was drafted as per the rules specified in GB/T 1.1-2009.
This Part replaced GB/T 16824.1-1997 Hexagon Head Tapping Screws with Collar;
compared with GB/T 16824.1-1997, this Part has the major technical changes as
follows.
--- Increase the Type-R end (Chapter 3);
--- Dimension a is measured from the small diameter of the first circle of perfect
thread (Figure 1);
--- Increase the provisions of stainless steel materials, mechanical performance as
per GB/T 3098.21, surface simplified treatment and passivation treatment as per
GB/T 5267.4 (Table 2);
--- Increase the provisions of untreated surface of steel nuts, and non-electrolytically
applied zinc flake coating technical requirements as per GB/T 5267.2 (Table 2);
--- Only allow to omit the markings of galvanizing technical requirements given in
marking example (Chapter 5).
This Part adopts re-drafting method to modify and use ISO 7053.2011 Hexagon
Washer Face Tapping Screws (English Edition).
The technical differences and causes between this Part and ISO 7053.2011 are as
follows.
--- In the normative references, use national standards to replace the international
standards (Chapter 2); add the reference of GB/T 90.2 (Table 2), and GB/T 1237
(5.1); delete the reference of ISO 724 and ISO 965-1, so that conform to China’s
fastener basic standard;
--- Increase the packaging technical requirements (Table 2); so that conform to
China’s fastener basic standard;
--- Modify the marking examples into simplified marking examples (5.2); so that
conform to the provisions of GB/T 1237.
This Part was proposed by China Machinery Industry Federation.
This Part shall be under the jurisdiction of National Technical Committee for
Standardization of Fastener (SAC/TC 85).
Drafting organizations of this Part. China Productivity Center for Machinery.
Participating drafting organizations of this Part. Machinery Industry General Parts
Product Quality Supervision and Inspection Center, and Ningbo Zhongji Machine Parts
