Introduction
Semi-tubular rivets are one of the most efficient permanent fastening solutions used in OEM manufacturing. Their partially hollow shank reduces the force required for installation while producing consistent, repeatable joints suited to high-volume production. They are especially valuable where manufacturers seek dependable automated assembly and long production runs.
Why Manufacturers Choose Semi-Tubular Rivets
• Lower installation force
• Faster assembly cycles
• Reduced equipment wear
• Repeatable joint formation
• Permanent fastening in a single operation
• Controlled pivot joints where required
• Excellent compatibility with automated riveting equipment
Automated Rivet Feeding and Assembly
One of the greatest advantages of semi-tubular rivets in production is their compatibility with automated assembly systems. Rivets are commonly oriented and supplied through vibratory feeder bowls and feed tracks that automatically present each rivet to the installation tooling in the proper orientation.
Historically, operators often hand-loaded the components being assembled while the riveting machine automatically fed and installed the rivet. Today, many manufacturers are moving toward conveyor-fed, indexed, and robotic work cells where the components themselves are automatically presented to the riveting station. Combined with automatic rivet feeding, these systems provide exceptional production throughput, repeatability, and quality.
Production Design Considerations
Proper rivet selection involves evaluating grip range, head style, shank diameter, material, hole size, installation method, and whether the assembly requires a rigid joint or a controlled pivot. These decisions directly influence assembly efficiency, joint performance, and long-term reliability.

Materials
Semi-tubular rivets are produced in carbon steel, stainless steel, brass, aluminum, and copper. Material selection should consider strength, corrosion resistance, conductivity, appearance, environmental exposure, and manufacturing requirements.
Production Quantities and Custom Designs
Many OEM manufacturers specify made-to-print semi-tubular rivets optimized for their assembly equipment and production requirements. G-Fast supplies both standard and custom production rivets and reviews customer drawings for manufacturability, feasibility, and cost-effective production before manufacturing begins.
FASTENEERING® Perspective
G-Fast reviews customer drawings and specifications for manufacturability, feasibility, and cost efficiency. When appropriate, we may recommend alternative rivet geometries, materials, or production methods that improve manufacturability or economy. Any recommendation must be approved by the customer’s engineering team and incorporated into an updated drawing before production.
