Metal Fabrication
Rivets are commonly used to assemble sheet metal in a variety of metal fabrication processes. Aircraft and automobiles make extensive use of riveted aluminum and steel alloys for structural components. Rivets provide a reliable joint that can withstand vibration and load stresses over time. They are often used for external panels as well as internal brackets, bulkheads and support structures. Solid aluminum rivets are popular in aircraft assembly while steel rivets with aluminum heads provide joints between aluminum and steel alloys in automotive manufacturing.
Machinery Manufacturing
Heavy machinery also utilizes rivets for structural assembly. Earth moving equipment, agricultural machinery, cranes and construction equipment all rely on rivets to create strong, rigid frames. Critical load bearing joints are often reinforced with multiple rows of rivets or rivets with increased diameters. Stainless steel and carbon steel rivets join steel structural components and provide corrosion resistance needed in rough operating environments.
Shipbuilding
Ship and boat hulls have long been assembled with rivets due to their strength, reliability and resistance to corrosion in marine environments. The famous luxury liner Titanic used over three million rivets in its construction in early 1900s. Modern shipbuilding has transitioned to welding for most steel hull structures, but aluminum vessels like speedboats still utilize rivets for assembly. Stainless steel rivets join parts above and below waterlines that require maximum corrosion protection.
Bridges and Infrastructure
Civil engineering projects like bridges, transmission towers and railways all involve structural steel fabrication. Heavy carbon steel rivets provide the high strength needed for these critical infrastructure components. Bridge trusses are assembled from formed steel sections using hot driven rivets. The Golden Gate Bridge in San Francisco used over 1.2 million carbon steel rivets in its construction completed in 1937. Transmission towers rely on rivets to resist wind, ice and vibration forces. Railroad and subway tracks are joined with hardened steel rivets designed to handle repeated loading from trains passing over.
Construction and Roofing
Softer aluminum and copper rivets are ideal for general building construction and roofing applications. Aluminum rivets secure aluminum flashing, downspouts and siding to building frames. Solid copper rivets join copper sheets used for architectural flourishes, window frames and roofing. Monel rivets, made of nickel-copper alloy, provide strength with good corrosion resistance for coastal building projects. When installing composite roofing like standing seam metal panels, self-drilling stainless steel rivets provide an easy, one-step fastening solution.
Woodworking and Furniture Making
Woodworking craftsmen selectively utilize rivets in furniture projects when appropriate for the design. Brass rivets provide attractive decorative accents when installed along corners, joints or on leather pads on chair legs. Copper or brass rivets also construct the copper pans and assemblies inside pipe organs. For securing mechanical joints and hinges, stainless steel and steel rivets provide sturdy function in wooden furniture subject to wear. Inexpensive aluminum and mild steel rivets join internal wooden parts hidden from view.
Leatherworking
Leather artisans and leather goods manufacturers rely extensively on rivets to assemble and reinforce leather products. Small round head aluminum rivets discretely join leather sheets while providing flexibility needed for garments and apparel. Tubular and split rivets allow sections to be riveted together with the post or shaft passing through an existing hole instead of hole punching afterward. This helps maintain structural integrity when working with sensitive or brittle vintage leathers. In heavy duty leather goods like belts, saddles, holsters and industrial belts, copper, brass and stainless steel rivets provide superior strength.
Electronics Manufacturing
In electronic device and computer manufacturing, small specialty rivets join precision sheet metal enclosures, brackets and assemblies. Stainless steel provides strength for the tiny rivets along with soldering compatibility. Some pop rivets are designed specifically for electronics assembly with flush breaking mandrels to eliminate remnants of the rivet shaft inside enclosures. Miniature aluminum rivets assemble delicate electronics cooling fins and heat sinks. Rivets make serviceability easier since they can be drilled out if needed unlike epoxy compounds.
Automotive Repair and Modification
For auto body repair, enthusiasts and professionals rely on pop rivets for patching panels, securing trim and piecing together custom fabrications. Stainless steel and aluminum pop rivets have a socket head that snaps off after setting leaving a clean finish. Blind rivets can recess fully into a drilled hole to hide the mechanical fastener for smooth exterior panels. For adding roll cages, skid plates, brush guards and other aftermarket parts, standard steel and aluminum rivets provide simple fabrication. Large flange head rivets maximize surface contact for structural modifications.
While welding and adhesives continue to advance, the many uses for rivets keep this basic mechanical fastener firmly entrenched in manufacturing and construction. New specialty rivet materials like composites and micro-rivets expand potential applications. But traditional steel, aluminum, copper, brass and stainless steel rivets remain staples thanks to their strength, reliability, corrosion resistance and ease of installation. Understanding proper rivet sizing, materials selection, hole spacing/patterns and installation methods allows for optimal rivet usage. Whether assembling delicate electronics or structural steel skyscrapers, rivets deliver versatile, economical fastening solutions. CNC Milling CNC Machining
