Fastener variety and function selection of industrial solutions

The usual fastening methods of the vehicle fasteners include bolts, screws, double-headed studs with nuts or threaded holes, self-tapping screws with prefabricated holes, clip pipe clamp embedded, and clamping ring hoop.

Its main application features are as follows:

1. The type of bolt, screw, double stud, and nut or thread hole matching is mainly used for high-strength connection pair with large loads, which have the characteristics of simple structure and stability.

2. self-tapping screw and prefabricated hole matching types are generally used for lightweight objects, such as the interior and small electrical parts fixed on the metal sheet.

3. Buckle, pipe clamp-type plastic fasteners are generally used for wiring harnesses and other small-diameter pipes fixed into the sheet metal class.

4. Clamp ring hoop for low-pressure hydraulic or pressure system, cooling pipe, etc. Each bolt's strength and friction coefficient are clearly defined, and the preload it can provide varies according to different torque strategies. Still, its minimum preload can be determined under a specific torque strategy. After obtaining the minimum preload required by the connection point and comparing which bolts can provide a minimum preload greater than it, you can choose the most economical specifications and performance levels. The following are the general steps for selection:

1. Determine the connection: tensile, shear, or composite loads.

2. According to the connection mode to determine the connection sub-working load;

3. Calculate the axial load and tangential load borne by the bolt;

4. Determine the minimum clamping force;

5. Check the surface pressure of the clamping part to prevent crushing;

6. Determine the appropriate specifications and performance levels.

1. Bolts: Bolts are generally matched with nuts (usually plus a washer or two washers) and used for connecting and fastening occasions.

2. Nuts: nuts and bolts match the use.

3. screws: screws are usually used alone (sometimes with washers) and generally play a tightening or tightening role.

4. stud: The stud is generally threaded at both ends (single-head stud is single-end with thread). Usually, a rib is firmly screwed into the body of the part; the other end matches with the nut and plays the role of connection and fastening, but to a large extent, it also has the role of spacing.

5. Washer: Washer is used between the supporting surface of bolts, screws, and nuts and the process supporting surface to prevent loosening and reduce the stress of the supporting surface.

6. self-tapping screw: the workpiece screw hole matching with the self-tapping screw does not need to be tapped in advance, and the internal thread is formed when the self-tapping screw is screwed in.

7. Rivets: One end of the rivets has a head, and the rod part has no thread. When used, the rod part is inserted into the hole of the connected part, and then the end is riveted tightly to connect or tighten.

8. Pin: When used, the pin is inserted into the workpiece and usually plays a connection or positioning role.

9. Stop ring: The stop ring is usually on the shaft or in the hole, limiting the workpiece's axis.

10. wood screws: wood screws are used to screw into the wood to connect or tighten.
