Manufacturers talk about the classification of standard fasteners

Release date:2018-02-06 The author: Click:

Each industry has its own standard products. The meaning of the standard is the standard, and the fastener industry is no exception. At present, the standards we use in our ordinary business are the following:


DIN - German National Standard (German Standard) ASME - American Society of Mechanical Engineers Standard


JIS-Japan National Standard (Japanese Standard) BSW-The British National Standard


GB-Chinese National Standard (GB) ANSI-American National Standard (American Standard)


The GB-National Standard is one of many standards in China, and there are also industry standards, professional standards, and departmental standards.


In addition to some basic dimensions such as head-to-edge, head thickness, etc., the most important are the differences in the thread parts. GB, DIN, JIS and other threads are all in MM (mm) units, collectively referred to as metric thread.


Another thread like ANSI, ASME, etc. is called American Standard thread in inches. In addition to the metric thread and the American thread, there is also a BSW-inch standard, the thread is also in inches, commonly known as Wyeth's thread.


The metric thread is in MM (mm) and its cusp angle is 60 degrees. Both American and British threads are in inches. The cusp angle of the U.S. thread is also 60 degrees, while the cusp angle of the U.S. thread is 55 degrees.
