Semi-Tubular Rivets Supplier for OEM and Industrial Applications
When a permanent mechanical joint needs controlled forming, repeatable assembly and a compact fastener design, semi-tubular rivets are often a practical choice. Unlike a fully solid rivet, a semi-tubular rivet has a partially hollow end that can be flared, rolled or otherwise formed during installation. This design can support efficient assembly while reducing the forming force required for some applications.
Yueqing Yiwan Hardware Production Co., Ltd. supplies stainless steel semi-tubular rivets and other customized metal components for overseas buyers, OEM manufacturers and engineering teams. As a comprehensive hardware factory, Yiwan combines multi-station cold upsetting, CNC machining, automatic turning, manual instrument machining and stamping capabilities to support different rivet and component requirements.
Whether you need a standard-style part or a rivet developed from a drawing, sample or application requirement, Yiwan can review the technical information and advise on a suitable production approach. Product dimensions, material grade, head design, hollow depth, tolerances and surface finish should be confirmed against your drawing and intended assembly method before quotation.

What Are Semi-Tubular Rivets?
A semi-tubular rivet is a permanent fastener with a hollow section at the end of its shank. During installation, the hollow end can be formed to secure the joined components. The partially hollow construction distinguishes it from a solid rivet while retaining the basic advantages of a riveted joint: a compact profile, no threaded components and a permanent connection after setting.
The correct semi-tubular rivet depends on more than the outside diameter. Engineers and purchasing teams may need to evaluate:
- Rivet head style and head dimensions
- Shank diameter and length
- Hollow-end geometry and depth
- Material and required mechanical performance
- Joint thickness and hole condition
- Installation equipment and forming method
- Dimensional tolerances and inspection requirements
- Surface condition, corrosion environment and finish
These details influence both part performance and the stability of the assembly process. For that reason, a qualified semi-tubular rivets supplier should evaluate the complete specification rather than quote only from a general product name.
Custom Semi-Tubular Rivets Made to Your Specification
Yiwan supports custom rivet and metal-component production for applications where an off-the-shelf part does not meet the required geometry or material specification. Buyers can provide a technical drawing, sample, photographs with dimensions or a written requirement for review.
Custom Sizes and Geometry
Semi-tubular rivets can be specified around the needs of the joint and the installation process. Depending on the application, the design review may cover the rivet head, shank, hollow section, total length, concentricity and dimensional tolerances. Exact size availability and manufacturability depend on the drawing, selected material, tooling requirements and production process.
Yiwan will confirm the feasible specification after reviewing the technical information. This approach helps avoid a mismatch between the quoted rivet and the customer’s actual assembly conditions.
Material Selection
Yiwan manufactures and supplies stainless steel semi-tubular rivets and other metal hardware components. The website also identifies aluminum, copper, iron, stainless steel, aluminum alloy and cold-rolled steel among material options for tubular-rivet production. The final material grade should be selected according to the required strength, corrosion resistance, conductivity, appearance, forming behavior and application environment.
Material options and grade availability should be confirmed for each project. If your drawing specifies a particular stainless steel grade, carbon-steel grade, copper alloy or aluminum alloy, include that information in your inquiry so the production and quotation review can be based on the actual requirement.
Surface Finishes
The appropriate surface finish depends on the base material, service environment, appearance requirements and downstream assembly process. Yiwan can review requested finish requirements as part of the technical quotation process. Your specification may identify the required surface condition, plating or coating system, passivation requirement, color, gloss level or other appearance criteria where applicable.
Do not select a finish based only on appearance. The finish may also affect corrosion protection, conductivity, dimensional fit, friction and compatibility with the joined materials. For accurate quotation, provide the finish designation or describe the operating environment together with the drawing.
Yiwan’s Manufacturing Capabilities
Yiwan Hardware is a comprehensive factory integrating several manufacturing processes for rivets and customized metal parts. Its stated capabilities include:
- Multi-station cold upsetting for formed metal components
- CNC machining for precision features and secondary operations
- Taiwan automatic machines
- Ningbo automatic machines
- Manual instrument machining
- Stamping and punch processing
This combination allows the production method to be considered around the part design instead of forcing every requirement into one process. Cold forming may be considered for suitable high-volume formed components, while CNC, automatic turning or stamping can support other geometries and secondary features. The appropriate process depends on the material, dimensions, tolerances, tooling and expected production requirements.
For buyers, the benefit is a single manufacturing partner for semi-tubular rivets and related custom hardware, including pins, automotive parts, door-lock parts, electrical hardware and other precision metal components.
Applications for Semi-Tubular Rivets
Semi-tubular rivets are used in assemblies where a permanent fastening method and controlled end forming are suitable. The final selection must be verified against the joint design and installation process, but typical application areas may include:
Automotive Components
Automotive parts often require compact metal components that can be integrated into mechanisms and subassemblies. Yiwan supplies customized automotive parts and can review rivet requirements for automotive-related applications based on the customer’s drawing and assembly conditions.
Door Locks and Hardware
Rivets may be used in moving or fixed hardware assemblies, including door-lock components and related mechanisms. Head dimensions, joint movement, material compatibility and forming method should be considered before production approval.
Electrical Hardware
For electrical hardware, material choice and surface condition can be important in addition to mechanical fastening. Buyers should identify conductivity, insulation, corrosion and appearance requirements where relevant. Yiwan manufactures electrical hardware and can review a semi-tubular rivet requirement as part of a broader custom-component project.
General Industrial and OEM Assemblies
Semi-tubular rivets can also be considered for industrial equipment, mechanisms, consumer products and OEM assemblies that need a permanent, low-profile fastening solution. The correct design depends on the materials being joined, total joint thickness, access to the assembly and available riveting equipment.
How to Order Custom Semi-Tubular Rivets
A clear technical inquiry helps a supplier confirm feasibility and prepare a more accurate quotation. Include as much of the following information as available:
- Technical drawing, 3D file or sample reference
- Required material and grade
- Rivet head type and dimensions
- Shank diameter, length and hollow-end requirements
- Dimensional tolerances and inspection criteria
- Surface finish or surface-condition requirements
- Joined-material information and total joint thickness
- Installation method or riveting equipment
- Application environment and performance requirements
- Estimated purchasing quantity or production plan
Yiwan can then review the drawing, material, production method and requested finish. If any information is missing, the engineering or sales team can identify the details needed to continue the quotation discussion. Final specifications, pricing, tooling requirements, production arrangements and delivery terms should be confirmed for each project.
Quality and Specification Review
For a custom fastener, quality begins with controlling the specification. Before placing an order, confirm that the supplier understands the drawing revision, critical dimensions, material grade, surface requirements and inspection expectations.
Yiwan’s production capabilities cover forming, machining and stamping processes that can be selected according to the product design. A project review should establish which dimensions are critical to installation, which surfaces are functional and what documentation is required for approval. Any special inspection plan, material documentation or test requirement should be stated in the inquiry so it can be reviewed before quotation.
This specification-led process is especially important for semi-tubular rivets because the hollow-end geometry and forming behavior affect how the rivet is installed and how the finished joint holds the components together.
