Rivets are a popular type of mechanical fastener used to join and assemble materials. Though often associated with metalworking, rivets have many versatile uses across various industries due to their strength, durability, and ease of installation. In this article, we will explore the functionality and benefits of rivets as well as their numerous applications.
What Are Rivets?
A rivet is a short metal pin with a head on one end that is inserted through holes in multiple layers of material. The unheaded end is then mechanically deformed with a riveting hammer or riveting machine to create a second head that sandwiches the materials together. The rivet shank fills the hole and the heads on both sides grip the materials to form a solid, permanent attachment.
Rivets come in a variety of head shapes, shank lengths and diameters, and materials. Common head shapes include round, brazier, countersunk, and pan heads. Shank lengths range from 1/8 inch to several inches. Aluminum, steel, copper, and Monel are popular rivet materials, each offering different levels of strength for various applications.
Benefits of Rivets
Rivets provide a number of advantages that make them a popular choice across many industries:
- Strength - The riveting process work-hardens the shank, creating a strong connection capable of withstanding tremendous shear and tensile loads. Rivets form a solid attachment and will not come loose over time.
- Durability - Riveted joints are resistant to vibration, shock, and fatigue loads. The deformation of the rivet shank makes rivets resistant to loosening.
- Easy Installation - Rivets can be quickly and easily installed with hand tools or pneumatic rivet guns without requiring welding, drilling/tapping, or special skills. Speed of installation makes rivets ideal for production environments.
- Reusability - Rivets can generally be removed and replaced if needed for repairs or modifications. Holes may need re-drilling if enlarged.
- Material Versatility - Rivets can join dissimilar materials like metals to plastics or glass. The rivet shank is deformed rather than melted like soldering or welding.
- Appearance - Countersunk rivets provide a smooth finished surface. Riveting eliminates unsightly welds, adhesives, or visible fasteners like bolts/screws.

Common Uses of Rivets
Rivets have many diverse applications across countless industries. Some of the most prominent uses include:
Aircraft Construction
Rivets are the preferred fastener in aircraft construction for their vibration resistance and ability to withstand extreme environments. Rivets hold together aluminum fuselage skins, wing panels, engine nacelles, control surfaces, and landing gear assemblies. Recent aircraft models may use specialized structural rivets like flush head rivets.
Metal Building Construction
The manufacturing of metal building systems heavily utilizes rivets to assemble frame components, join wall and roof panels, attach gutters/downspouts, and more. Steel rivets provide high shear strength for structural joints and weathertight connections.
Automobiles and Trucks
While welds, bolts, and adhesives have displaced some riveted joints, rivets are still commonly used in automobile/truck frames, chassis components, body panels, driveshafts, and interiors. Rivets allow for quick assembly and flexibility in joint design.
The sheet metal skins of appliances often utilize rivets for clean, sturdy assembly. Appliance uses include cases, doors,panels, brackets, motors, handles, latches, and more. Stainless steel rivets withstand appliance forces and prevent corrosion.
Miniature rivets precisely join thin, fragile components of electronic devices like cell phones, tablets, laptops, and medical equipment. Electronics rivets are designed with flush heads to maintain a smooth exterior surface.
Marine-grade rivets are indispensible in the construction of boats and ships. They assemble hull components, decks, railings, masts, cargo holds, ramps and more. Copper rivets provide corrosion resistance in ocean environments.
Though increasing use of soldering and adhesives, rivets still fasten pipes, sheets, brackets, clamps, ducts, and fittings. Rivets allow reliable leak-free joins of dissimilar piping materials like PVC to copper.
Small decorative rivets called jewelry rivets attach links, clasps, bezels, and findings on necklaces, bracelets, chains, and other jewelry items. Jewelry rivets provide an attractive fastening method for jewelry assembly.
Musical Instruments
Brass and copper rivets are traditionally used in the manufacturing of musical instruments. Applications include joining wood frame components on acoustic guitars, drum shells, bagpipe chanters, and more.
Recreational Products
Rivets find wide usage in things like playground equipment, bleachers, golf carts, bicycles, weight benches, and other recreational items at parks, schools, and athletic facilities. Rivets withstand weather and repetitive loads.
The versatile rivet has proven itself to be a reliable, easy-to-use fastener capable of meeting the demands of a diverse range of products and structures. Advancements in rivet designs and installation processes will enable rivets to continue meeting evolving fastening challenges and assembly needs across many industries. Whether the need calls for miniature electronic rivets or bulky structural rivets, rivets will remain a top choice for mechanically fastening materials together. CNC Milling CNC Machining
