hex bolt and nut steel structure hexagon head half thread bolt

The nut is a part that is screwed together with a bolt or screw to play a fastening role, and all production and manufacturing machinery must use a component. There are many kinds of nuts, common national standard, British standard, American standard, and Japanese standard nuts. According to the different materials, nuts can be divided into carbon steel, stainless steel, plastic steel and other types.

Type and standard of nuts

According to the attributes of the nut, there are mainly national standard (GB), German standard (DIN), international standard (ISO), Japanese standard (JIS), American standard (ASTM/ANSI) and other standards. Among them, the national standard, German standard, and Japanese standard are represented by M (such as M8, M16), and the United States system and British system are represented by fractions or # (such as 8#, 10#, 1/4, 3/8).

Material and characteristics of nuts

Nut materials include carbon steel, stainless steel, copper, alloy, etc. Plastic nuts are mostly made of nylon 66 (NYLON66), which has the characteristics of insulation, non-magnetic, good acid and alkali resistance, but low torque and poor strength.

Nut locking measures

To prevent nuts from loosening, you can use lock nuts in three ways: 1. Use two identical nuts on the same bolt to increase the tightening torque; 2. 2. Use special anti-lock gaskets and nuts; 3. Screw a small diameter countersunk screw into the inner round surface of the nut to exert centripetal force on the thread.
