Carbon Steel Black Oxide High Strength Hex Head Bolts Grade 10.9 12.9 Astm A490

1. Description:

   

      The external hexagonal screw is a hexagonal screw, also known as a hexagonal screw. The Chinese standard for external hexagonal screws is based on Chinese standard parts. Abbreviated as the national standard. Then this external hexagonal screw standard refers to the external hexagonal screw national standard.

 

        The outer hexagon bolt standard has one standard is the grade standard. Grade standard is divided into 4.8 grade and 8.8 grade. These two grades are used in particular on the market. Especially 4.8 grade external hexagonal bolt. Because it is much cheaper than 8.8 class outer hexagon bolt. Use more widely, of course. Some. But for high-demanding products. Because of the high requirements of hardness and other aspects. This requires the use of 8. 8 grade external hexagon bolt. 8.8 class external hexagon bolt from the hardness and torque of screws, etc. More secure in the use of products. More fastening. More stable.

Mechanical part, cylindrical threaded fastener with nuts. A type of fastener consisting of a head and a screw (a cylinder with external threads), which shall be matched with the nut. Used to fasten two parts with through holes. This form of connection is called bolt connection. If you unscrew the nut from the bolt, you can separate the two parts, so the bolt connection is detachable.
