What is Bulb Tite Rivet?
Bulb tite rivets are waterproof rivets with a large riveting area. The rivet tail has been specially designed to create a new “bulb-like” extension when installed.
In practice, Bulb tite rivets are often used with gaskets in order to achieve excellent waterproofing. Bulb tite blind rivets can be riveted to soft, thin-walled or porous materials, and its unique design is designed to distribute the load evenly, avoiding material breakage or pull-through.
3 Main Features of Bulb Tite Rivets
Bulb tite rivets are used frequently in applications that require waterproofing. So what’s the reason? Let’s take a closer look.
1. Bulb-like Body Extension
The most significant feature of Bulb tite rivets in terms of appearance and construction is that the end of the rivet, when installed, creates a rounded extended shape similar to a light bulb. This design provides full coverage of holes and the backside of the parent material, and the expanded shape has no sharp edges.
The bulb tite rivets have a lot of rivet expansion. After the expansion of the tail, the contact area with the base material is significantly larger than that of ordinary blind rivets. Therefore, bulb tite rivets can effectively disperse the pressure exerted on the base material, preventing soft, thin-walled or brittle materials from being pulled through or deformed due to excessive localized pressure.
2. High Clamping Force
Bulb tite blind rivets’ high clamping force is one of its distinguishing features, in addition to its ability to prevent pulling through soft materials. This feature is particularly useful in connection applications that require reliable fixing, high dynamic loads or vibration environments.
Bulb tite rivets provide a large contact area for even distribution of clamping force. As a result, Bulb tite rivets can provide ultra-high clamping forces for connections.
Advantages of High Clamping Force
The high clamping force of rivets can provide many benefits. The following are the main advantages:
- Ensure stable connection
- Prevents the base material from shifting or slipping
- Improves vibration resistance
3. Excellent Sealing Performance
Why do Bulb Tite Rivets provide excellent sealing performance? It’s actually due to two main factors:
- The bulb-shaped tail extension
- Sealing gasket
With the combined effect of these two measures, bulb tite blind rivets can provide efficient protection against water, dust and air. As a result, this type of rivet is widely used in construction, marine, automotive, industrial equipment and electronics, providing a reliable solution for applications requiring high sealing performance. Despite its high cost, its excellent performance makes it an ideal choice for demanding connection scenarios.

3 Disadvantages of Bulb Tite Blind Rivets
Of course, there is no perfect product in the world.The unique features of Bulb tite rivets provide a great solution for customers. At the same time. bulb tite blind rivets has some disadvantages.
Higher Costs
Due to the unique rivet body design and functional requirements of bulb tite blind rivets, the cost of manufacturing them is higher than open end blind rivets.
Typically, the rivet body of bulb tite rivets is more difficult to produce, which can greatly increase production time and equipment costs. As far as I know, there are very few manufacturers in China who can produce perfect bulb tite rivets.
Back Space Needs to be Large
Bulb tite blind rivets require more space for the rivet body to expand than open type blind rivets. Therefore, bulb tite blind rivets are not suitable for confined areas.
Limited Strength
Bulb tite blind rivets have a high clamping force though. But the tensile and shear strength is not as good as structural rivets.
Applications of Bulb Tite Blind Rivets
Due to their high clamping force, corrosion resistance and waterproofing, bulb tite rivets are used in a variety of applications where waterproofing or lightweighting is required. Below are some common applications for bulb tite rivets:
- Construction and curtain walls: for fixing of aluminum alloys, fiberglass panels or composite materials. Examples include curtain walls, roof panels, partition walls.
- Automotive & Transportation: for roof components, plastic interiors, door panel fixing.
- Ship and marine equipment: deck, cabin equipment, shell fixing.
- Industrial equipment: for thin-walled metal casings, pipe supports, machinery protective covers. It can provide large area support and protect the base material.
- Home appliances and electronic equipment: for plastic shell, metal support structure fixing. Protect lightweight materials from being pulled through.
