Rivets are a simple yet versatile fastening system used in manufacturing, construction, and even everyday household items. A rivet consists of a cylindrical shaft with a head on one end. The shaft is inserted into pre-drilled holes in the materials being joined, and the empty end is deformed to create a second head. The force created locks the rivet in place, creating a permanent mechanical fastener. While other removable fasteners like screws or bolts may seem more useful, rivets have distinct advantages that make them ideal for many applications.
In manufacturing and industry, rivets are commonly used to assemble metal parts and structures. The aircraft and aerospace industries rely heavily on rivets to construct lightweight but sturdy airframes. Thousands of rivets hold together aluminum sheets to form fuselages, wings, and other components. Rivets create smooth exterior surfaces crucial for optimal airflow. They also evenly distribute stress loads across connected pieces. In bridges, trucks, railroad cars, and other large metal constructions, rivets provide reliable structural integrity under demanding conditions.
Rivets are also ubiquitous in consumer goods and household items. Jeans and other clothing use rivets to reinforce points of strain like pocket corners. Rivets attach handles to pots and pans for a solid grip. They fasten blades and other accessories to swiss army knives and multi-tools. Eyeglass frames, bicycle kickstands, ladders, gutters, and countless other everyday items rely on rivets for assembly and durability.
The popularity of rivets stems from their simple but ingenious design. Installation only requires access from one side of the workpieces. Holes are quickly punched or drilled to match the rivet shaft. Manual, pneumatic, or electric tools quickly insert and "buck" the rivet by crushing the empty end. This creates a permanent headed stud that won't loosen over time. The process is easily automated for large-scale production. Little surface preparation is needed compared to welding or bonding. And dissimilar metals can be riveted together with minimal corrosion issues.
Rivets come in a wide range of sizes, shapes, and materials to suit specific applications:
- Aluminum and steel rivets are common for high-strength structural connections. Stainless steel provides corrosion resistance. Copper or brass rivets avoid galvanic corrosion when riveting different metals.
- Drive rivets have pre-formed heads so they can be driven like a nail and bucked cold. Blind rivets can be installed from one side when there is only rear access. Split rivets are inserted in holes and mechanically expanded for a tight fit.
- Standard round head rivets provide the basic flattened bucked head. Countersunk rivets have a flush conical head for smooth surfaces. Large head rivets maximize load bearing surface area. Multi-grip rivets expand to accommodate different material thicknesses.
- Tiny micro rivets less than a millimeter in diameter are ideal for electronics and precision devices. Oversized structural rivets bear enormous loads in civil construction projects.
- Self-piercing rivets can cut and penetrate sheet metals in one step without pre-drilling. Special pull-through blind rivets can be set by pulling the stem rather than bucking the tail.
Installation best practices should be followed to get optimal results:
- Holes must match the rivet shaft diameter precisely. Loose holes will not allow the rivet to expand and grip properly. Excessively tight holes can split the surrounding material.
- Hole edges should be lightly deburred to prevent tearing or cracking during rivet setting. Hole depths should match rivet lengths to ensure proper bucking.
- Use rivet sets that fit the rivet head profile and diameter. Flat riveting hammers will damage rivet heads and surrounding material.
- Set rivets firmly until the bucked end is 1.5 times the shank diameter. Over or under driven rivets will not reach full strength.
- Stagger parallel rows of multiple rivets for best load distribution. Space at close intervals along stress concentration lines.
With the right techniques, rivets form invaluable permanent fastenings in countless manufacturing and construction applications. Their simplicity, strength, and ease of automation will ensure rivets remain a trusted fastening method for assemblies large and small. CNC Milling
