In some mechanical equipment, we often use the small part of hexagon flange face drill tail self tapping screw. The flange screw mainly plays a fixing role. Through the cooperation of screw and nut, the stability of products and machinery is strengthened! What is the function of hexagon flange drilling tail tapping screw? What are the specifications?
1、 What is a hexagon flange drilling tail tapping screw?
Hexagon flange face drilling tail tapping screw is one of the threaded fasteners that self tap and drill the matched female thread in the pre drilling of metal or non-metallic materials. Self tapping screws are mostly used for the connection between thin metal plates (steel plate, saw plate, etc.). When connecting, first make a threaded bottom hole for the connected part, and then screw the self tapping screw into the threaded bottom hole of the connected part. Since the thread table * of the self tapping screw has high hardness (≥ 45hrc), the internal thread can be tapped out in the threaded bottom hole of the connected part to form a connection. The price of hexagon flange drilling tail tapping screw is about 20 yuan.
2、 What is the specification standard of hexagon flange face drill tail self tapping screw?
The standard GB / t6177.1-2000 specifies that the thread specification is M5-M20, performance grades 8, 9, 10 and 12 are A2-70 and products, etc. * hexagon flange nuts of grade and B * nuts for d16mm.
3、 What is the function of hexagon flange drilling tail tapping screw?
The function of hexagon flange face drilling tail tapping screw is: hexagon flange face drilling tail tapping screw is that two identical nuts are screwed on the same bolt, and a tightening torque is added between the two nuts to make the bolt connection reliable. The working principle of hexagon flange lock nut is self-locking by using the friction between nut and bolt. However, the reliability of this self-locking will be reduced under dynamic load. On some important occasions, we will take some anti loosening measures to ensure the reliability of nut locking. Lock nut is one of the anti loosening measures.
