Semi-tubular rivets are widely used fasteners for assemblies that need reliable joining, clean appearance, and efficient production. Unlike solid rivets, semi-tubular rivets have a partial hole at the tail end. This design reduces the force needed during riveting while still providing strong mechanical fastening.
For OEM manufacturers, hardware factories, electrical component producers, lock manufacturers, and industrial assembly companies, choosing the right semi-tubular rivet is not only about size. Material, head type, shank diameter, hole depth, surface finish, assembly method, and production consistency all affect the final performance.
Yueqing Yiwan Hardware Production Co., Ltd. manufactures semi-tubular rivets, stainless steel semi-tubular rivets, tubular rivets, step rivets, copper rivets, pins, screws, nuts, CNC parts, cold forged parts and other customized hardware components for industrial applications.
What Are Semi-Tubular Rivets?
A semi-tubular rivet is a rivet with a solid head and a partially hollow shank. During installation, the hollow end is flared or rolled outward to lock the connected parts together. Because only the end needs to be formed, the installation force is lower than that of a fully solid rivet.
This makes semi-tubular rivets suitable for high-volume assembly, especially where manufacturers need stable fastening without damaging the surrounding components.
Semi-Tubular Rivets vs Solid Rivets vs Tubular Rivets
| Rivet Type | Structure | Main Advantage | Typical Use |
|---|---|---|---|
| Semi-tubular rivets | Partially hollow end | Lower setting force with good fastening strength | Hardware, locks, electrical parts, light assemblies |
| Solid rivets | Fully solid shank | High mechanical strength | Heavy-duty fastening and structural joining |
| Tubular rivets | Hollow through the shank | Easy forming and lightweight assembly | Light-duty products, decorative or low-load fastening |
Common Materials for Semi-Tubular Rivets
Steel Semi-Tubular Rivets
Steel semi-tubular rivets are commonly used where strength and cost control matter. They can be combined with surface treatments to improve corrosion resistance or appearance.
Stainless Steel Semi-Tubular Rivets
Stainless steel semi-tubular rivets are suitable for applications that require better corrosion resistance, cleaner appearance, or longer service stability in humid or demanding environments.
Copper and Brass Rivets
Copper and brass rivets are often used in electrical hardware, decorative parts, and applications where conductivity or appearance may be important.
Common Applications of Semi-Tubular Rivets
- Door lock parts and lock hardware
- Electrical hardware and switch components
- Hinges and small mechanical assemblies
- Automotive and motorcycle components
- Household appliance parts
- Tool accessories and small hardware products
- Custom OEM fastening applications
Key Specifications Buyers Should Confirm
| Specification | Why It Matters |
|---|---|
| Head diameter | Affects appearance, contact area, and assembly fit |
| Shank diameter | Controls hole fit and riveting stability |
| Rivet length | Must match the total assembly thickness |
| Hole depth | Affects forming force and tail expansion |
| Material | Determines strength, corrosion resistance, and forming behavior |
| Surface treatment | Supports corrosion protection, appearance, or matching with other parts |
| Tolerance | Important for automatic assembly and repeat orders |
How to Choose a Semi-Tubular Rivets Manufacturer
The right manufacturer should not only make the rivet shape. They should understand how the part will be assembled and how stable the product must be during production.
- Can they produce according to drawings or samples?
- Can they support different materials and surface finishes?
- Can they control diameter, length, head shape, and hollow depth?
- Do they have inspection equipment for batch consistency?
- Can they support samples before mass production?
