What are Rivets?
A rivet is a mechanical fastener that consists of two main parts - a smooth cylindrical shaft and a head. The shaft is inserted into holes in the materials being joined and the head is smashed against the material using powerful squeezing force from a riveting gun or hammer. This deforms the tail of the rivet to form a second head, creating a permanent joint.
Rivets come in a range of styles, sizes and materials like aluminum, steel, copper and more. The most common types are blind rivets, solid rivets and drive rivets. Blind rivets can be installed from one side when there is only access to one surface. Solid rivets require access to both sides. Drive rivets have serrations under the head that lets the rivet dig into softer materials like plastics.
Key Uses and Applications
Aircraft and Aerospace
One of the most common uses for rivets is in aircraft and aerospace applications. Rivets are extensively used in the manufacture of aircraft fuselages, wings, engine nacelles and other structures. Aviation rivets are typically lightweight aluminum alloys that offer the ideal balance of strength, weight and corrosion resistance needed. Rivets don't require welding, avoiding potential distortion and the need for extensive post-weld work. Riveted joints also absorb vibration well, preventing metal fatigue.
Beyond aerospace, rivets are commonly used in the manufacture of metal products like trailer homes, shipping containers, farm equipment and motor vehicle accessories. Steel and stainless steel rivets provide durable fastening for sheet metal parts, machinery housings, truck accessories and more. The installation of rivets is fast and economical compared to welding or adhesives. Riveting also allows easy disassembly for maintenance or part replacement.
Rivets have many construction uses, including fastening steel I-beams, pipes, HVAC ducting, aluminum siding and more. Stainless steel and copper rivets withstand outdoor weather exposure. Blind rivets are ideal for installing metal studs, joining galvanized sheet metal and any application where only one-sided access is available. Aluminum rivets are also used to fasten flashing, gutters and roofing.
In electronics manufacturing, tiny blind rivets securely fasten internal components of devices together. Blind rivets are ideal for this application because they can be installed from the front side only, keeping backsides clear for circuit boards and other electronics. Blind rivets help minimize device size while providing solid, reliable fastening inside phones, appliances, computers and more.
Plastics and Composites
Along with metals, rivets can join engineered plastic, composites, fiberglass and other non-metal materials. Drive rivets have serrated shafts that tap and hold firm in plastics where smooth shanks would spin freely. Rivets provide robust fastening without the need to drill and tap threads or bond with adhesives. Riveting is fast and inexpensive compared to these other methods.
Rivets provide reliable fastening for industrial attachments like handles, hinges, latches and more. The flanged head and body of a rivet withstand repeated forces better than screws or adhesives alone. Machined aluminum or steel rivets also don't loosen over time like screwed handles. Press-in rivets easily join components like machine guards, nameplates, transaction drawers and any application where a permanent mechanical attachment is needed.
Jewelry makers use rivets to securely fasten pieces of metal jewelry together without glue or soldering. Copper and brass rivets provide an attractive alternative to modern adhesives and a more durable fastening than just wire wrapping. Rivet heads can also be an ornamental design element of the jewelry. Lap joints, butt joints and other intricate connections are easily achieved with small jewelry rivets installed with a hand-set tool.
Binding and Fastening
In stationery applications, small copper and brass rivets provide an attractive and functional alternative to stitches for binding paper, leather and bookbinding. Cutters and anvils specifically designed for hand setting 1/8" to 3/16” diameter rivets are used to peen the rivets over and clamp materials firmly together. Rivets won’t tear or wear like threads and provide a strong yet reversible way to bind materials.
Key Advantages of Rivets
After reviewing the many uses for rivets across products and industries, some key advantages emerge:
- Rivets create incredibly strong, permanent joints that withstand vibration and repeated forces better than many fasteners.
- Installation only requires access to one side for blind rivets, making them ideal for electronics, furniture and other assemblies.
- Riveted joints can be disassembled if needed for repair or part replacement.
- Riveting is fast, easy and economical compared to welding, tapping threads or adhesives.
- Rivets are available in a wide range of materials and sizes to suit the design needs.
- The installation process deforms the rivet tail rather than the materials being joined, preventing damage.
- Rivets distribute load over a wider area compared to screws or bolts.
For reliable, versatile and strong permanent fastening across countless applications, rivets are a trusted and proven choice. Understanding their capabilities and advantages allows engineers, designers and manufacturers to take full advantage of riveted joints.
While they may seem like humble pieces of hardware, rivets offer immense versatility and strength across a vast range of products and industries. From aircraft wings to jewelry, rivets are an economical, expedient and durable fastening solution. With an array of materials and specialty designs to choose from, rivets can tackle just about any permanent fastening need. The unique qualities of riveted joints make them a preferred solution in the most demanding applications. So don’t underestimate the power of the rivet - it’s often the best choice for securely and permanently joining materials together. CNC Milling CNC Machining
