Various Types Of Nuts Characteristics And Shortcomings

1. Ordinary outer hexagon - widely used, characterized by relatively large fastening force. The disadvantage is that there must be enough operation space during installation. When installing, you can use adjustable wrench, open end wrench or glasses wrench. The above wrenches need to be very large. Operating space.

2. The hexagonal hexagon socket - is the most widely used of all screws, because it has a relatively large fastening force, can be operated with an Allen key, easy to install, almost used in a variety of structures, the appearance is more beautiful and tidy, The disadvantage is that the fastening force is slightly lower than the outer hexagon, and the repeated use of the inner hexagon is easy to damage and cannot be disassembled.

3. Pan head hexagonal - mechanically seldom used, mechanical properties are the same as above, mostly used in furniture, the main role is to increase the contact surface with wooden materials and increase the ornamental appearance.

4. Headless hex - some structures must be used, such as the top wire structure that requires a large top force, or where the cylinder head needs to be hidden.

5. Countersunk head hexagon - mostly used in power machinery, the main role is the same as the inner hexagon.

6. Nylon lock nut--Inlay nylon ring in hexagonal surface to prevent loose thread structure and use on strong power machinery.

7. Flange nut - mainly to increase the role of contact with the workpiece, mostly used in pipes, fasteners have been stamped and cast parts.

8. Ordinary hex nut - the most versatile, and one of the most common fasteners.
