As a supplier of lantern rivets, I often encounter inquiries about the typical length of these fasteners. Lantern rivets, also known as tubular rivets, are a type of blind rivet that is commonly used in various applications, including automotive, aerospace, and construction. In this blog post, I will discuss the typical length of lantern rivets, factors that influence their length, and how to choose the right length for your specific needs.
Understanding Lantern Rivets
Before delving into the typical length of lantern rivets, it's essential to understand what they are and how they work. Lantern rivets consist of a tubular body and a mandrel. When the mandrel is pulled, the body of the rivet expands, creating a secure connection between two or more materials. Unlike other types of rivets, lantern rivets do not require access to both sides of the material being joined, making them ideal for applications where one side is inaccessible.
Typical Length of Lantern Rivets
The typical length of lantern rivets can vary depending on the specific application and the materials being joined. Generally, lantern rivets are available in lengths ranging from 6mm to 30mm. However, the most commonly used lengths are between 8mm and 16mm. These lengths are suitable for a wide range of applications, including thin sheet metal, plastic, and wood.
Factors Influencing Lantern Rivet Length
Several factors can influence the length of lantern rivets required for a particular application. These factors include:
- Material Thickness: The thickness of the materials being joined is one of the most critical factors in determining the length of the lantern rivet. The rivet should be long enough to penetrate through both materials and form a secure connection. As a general rule, the length of the rivet should be at least 1.5 times the total thickness of the materials being joined.
- Application Requirements: The specific requirements of the application, such as the amount of shear or tensile strength needed, can also influence the length of the lantern rivet. For applications that require high strength, longer rivets may be necessary to ensure a secure connection.
- Accessibility: The accessibility of the materials being joined can also affect the length of the lantern rivet. If one side of the material is inaccessible, a longer rivet may be required to reach the other side.
Choosing the Right Length of Lantern Rivets
Choosing the right length of lantern rivets is crucial to ensure a secure and reliable connection. Here are some tips to help you choose the right length:
- Measure the Material Thickness: Before selecting a lantern rivet, measure the total thickness of the materials being joined. This will give you an idea of the minimum length of the rivet required.
- Consider the Application Requirements: Consider the specific requirements of the application, such as the amount of shear or tensile strength needed. This will help you determine if a longer or shorter rivet is necessary.
- Consult with a Professional: If you are unsure about the right length of lantern rivets for your application, consult with a professional or a supplier. They can provide you with expert advice and help you choose the right rivet for your needs.
Types of Lantern Rivets and Their Lengths
There are several types of lantern rivets available, each with its own unique features and applications. Here are some common types of lantern rivets and their typical lengths:
- Closed End Blind Rivet: Closed end blind rivets are designed to provide a watertight and airtight seal. They are commonly used in applications where a high level of sealing is required, such as in automotive and aerospace industries. The typical length of closed end blind rivets ranges from 6mm to 20mm.
- Steel Hollow Lantern Rivets: Steel hollow lantern rivets are made of high-quality steel and are known for their strength and durability. They are commonly used in applications where a high level of strength is required, such as in construction and machinery. The typical length of steel hollow lantern rivets ranges from 8mm to 30mm.
- Countersunk Head Blind Rivet: Countersunk head blind rivets are designed to provide a flush finish on the surface of the material being joined. They are commonly used in applications where a smooth and aesthetically pleasing finish is required, such as in furniture and electronics. The typical length of countersunk head blind rivets ranges from 6mm to 16mm.
Conclusion
In conclusion, the typical length of lantern rivets can vary depending on the specific application and the materials being joined. When choosing a lantern rivet, it's important to consider factors such as material thickness, application requirements, and accessibility. By choosing the right length of lantern rivets, you can ensure a secure and reliable connection that will last for years to come.
