- With the rapid transformation of the economic development mode of the fastener industry, enterprises have to consider the need to make fine products, improve the technological content, and transform the original extensive production mode. Thus, the standard became the weapon in their hands. While enterprises regard quality as a lifeline, they must use standards as a nourishment to produce healthy vitamins and nutrients.
We are delighted to see that the basic standards led by the China Fastener Standardization Technical Committee have issued more than 10 new standards every year.
In 2009, a number of fastener standards and related standards were announced and implemented in 2010.
Fastener standards such as: GB/T802.3-2009 "hexagonal flange cap nut welding type", GB/T802.4-2009 "hexagonal low spherical cap nut welding type" GB/T802.5-2009 "Non Metal insert hexagonal locking cap nut welding type", GB/T923-2009 "hexagonal cap nut", GB/T3098.22-2009 "fastener mechanical properties fine-grained non-tempered steel bolt screw and stud" .
Fastener related standards such as: GB/T5267.4-2009 "fastener surface treatment corrosion-resistant stainless steel passivation treatment", GB/T5953.1-2009 "cold steel wire part 1 heat-treated cold-rolled steel wire", GB /T5953.2-2009 "Cold-free steel wire second part non-heat-treated cold-rolled steel wire", GB/T230.1-2009 "metal material Rockwell hardness test part 1 test method", GB/T4340.1-2009 "Vickers hardness of metal materials Part 1 test method", GB/T4340.4-2009 "Metal material Vickers hardness part 4 hardness value table", GB/T23904-2009 "Non-destructive testing ultrasonic surface wave detection method" and so on.
The newly developed standards include non-tempered cold-rolled steel hot-rolled wire rods and cold-rolled steel hot-rolled wire rods; revised GB/T3098.1-20XX “Mechanical performance bolts and studs for fasteners†are also submitted for approval. in.
Through the extensive development, revision and publication of fastener standards, we can see that the fastener industry has achieved brilliant results in these years. In the future, these standards will lead the healthy development of China's fastener industry to the international advanced level.
