At Rapid Rivet and Fastener Corp., we supply a wide range of Mil Spec semi tubular rivets as well as custom rivets designed to meet specialized application requirements. Our inventory includes aerospace approved specifications, proprietary series, and multiple material and head style options.Semi tubular rivets are an economical fastening solution for joining two materials when a solid structural rivet is not required. Because the shank contains a partial hollow section, these rivets require significantly less installation force and can be installed using simple tooling.
What Are Semi Tubular Rivets?
- Semi tubular rivets are mechanical fasteners with a partially hollow shank at the end of the rivet. During installation, the hollow portion of the rivet shank rolls outward using a rivet press and anvil. This process forms a secure joint between materials.
- Because less material must be deformed during installation, semi tubular rivets require less force than solid rivets while still maintaining strong mechanical performance.
- Semi tubular rivets can create permanent fastening or controlled movement joints depending on the application.
-
- Common characteristics include:
- -Lightweight construction while maintaining structural reliability
- -Lower installation force compared to solid rivets
- -Consistent fastening performance in high production environments
- -Customizable head styles, materials, and finishes
- -Lightweight construction while maintaining structural reliability
Benefits of Semi Tubular Rivets
Semi tubular rivets provide several advantages compared to other fastening methods.
Reduced installation force: The hollow shank allows the rivet to deform easily during installation, reducing required press force.
Faster assembly processes: Manufacturers can install semi tubular rivets quickly in automated or high volume production environments.
Cost efficient fastening: Semi tubular rivets use less material and require simpler tooling than solid rivets.
Reliable mechanical strength: Despite the hollow shank, semi tubular rivets provide strong shear strength and consistent fastening performance.
Versatile application capability: These rivets can be used for rigid joints or hinge type assemblies depending on installation technique.
Common Applications for Semi Tubular Rivets
Semi tubular rivets are widely used in industries that require reliable fastening with efficient installation.
-Aerospace: Semi tubular rivets are used in aircraft interior assemblies, control surfaces, and lightweight structural components. Many aerospace applications require rivets that meet Mil Spec standards for safety and reliability.
-Automotive: Automotive manufacturers use semi tubular rivets for brake linings, seat frames, hinge assemblies, and vibration resistant joints.
-Electronics: These rivets are used to secure circuit boards, electrical enclosures, and electronic housings because they provide lightweight fastening with minimal vibration impact.
HVAC and Industrial Equipment: Semi tubular rivets are often used in duct systems, sheet metal assemblies, and ventilation components where corrosion resistant finishes are important.
Consumer Products and Appliances: Many appliance and hardware manufacturers use semi tubular rivets for hinges, brackets, and moving components.
Frequently Asked Questions
What is the difference between a semi tubular rivet and a solid rivet?
Semi tubular rivets contain a hollow section at the end of the shank, which reduces the force required for installation. Solid rivets require significantly more force but provide maximum structural strength.
Where are semi tubular rivets commonly used?
They are commonly used in aerospace assemblies, automotive brake systems, electronics enclosures, appliances, and HVAC equipment.
Are semi tubular rivets permanent fasteners?
Yes. Once installed, semi tubular rivets form a permanent mechanical joint. However, they can also be installed in a way that allows controlled movement for hinge assemblies.
