What is the relationship between the diameter, length and riveting strength of blind rivets?

As a commonly used connector, blind rivets have a close relationship between their diameter, length and riveting strength. These parameters not only determine the effect of the rivet, but also directly affect the reliability and durability of the connection.
The diameter of blind rivets is one of the important factors affecting their riveting strength. Rivets with larger diameters have larger cross-sectional areas, which can provide greater shear and tensile strength. However, too large a diameter can also bring some problems, such as difficulty in forming the upsetting head and easy deformation of the sheet. On the contrary, rivets with too small a diameter may cause connection failure due to insufficient strength, and the number of rivets needs to be increased to compensate, which will undoubtedly increase the difficulty and cost of construction.
The length of the rivet is closely related to the total thickness of the connected parts. The appropriate length can ensure that the rivet fully penetrates the connected parts and forms an effective upsetting head, thereby providing a reliable connection. If the shank is too long, the rivet head will be too large and the shank will be easily bent; if the shank is too short, the upsetting amount will be insufficient and the rivet head will not be fully formed, which will seriously affect the strength and tightness of the riveting. Therefore, it is very important to choose the right rivet length.
Riveting strength is an important indicator to measure the performance of the connector. It depends on the strength of the rivet and the strength of the connected plate. During the riveting process, the rivet shank fills the gap of the rivet hole due to pressure to form a tight connection. The diameter and length of the rivet directly affect the strength and tightness of the connection. Generally speaking, rivets with moderate diameter and length can provide the best riveting strength.
In summary, there is a close relationship between the diameter, length and riveting strength of blind rivets. In practical applications, we need to select the appropriate rivet specifications based on factors such as the material, thickness and working environment of the connected parts to ensure the reliability and durability of the connection.
