Rivets have been used since ancient times to join materials together. Today, they are widely used in many industries due to their simple design, reliability, and cost-effectiveness. Here are some of the top uses for rivets in manufacturing, construction and engineering:
Aircraft and Aerospace Applications
Rivets are extensively used in the assembly of aircraft frames and parts. Aircraft-grade rivets come in light-weight aluminum, steel, titanium, and other alloys. They are specifically designed to withstand vibration, extreme temperatures, and loads experienced during flight. Rivets help join the fuselage skins to the frame and glue composite airframe components. The riveted design provides excellent mechanical fastening strength while allowing for some flexing.
Automotive Manufacturing
The automotive industry relies on a mix of welding and riveting to construct car bodies and frames. Rivets provide a clean and consistent method of joining metal sheets, extrusions, and stamped parts through-out the vehicle. Body panels, doors, hoods, trunk lids, and roofs are commonly joined with rivets. They also assemble chassis components like the frame, sub-frame, engine cradles. Riveting produces joints that resist fatigue and shock loads better than welding in high-stress areas.
Appliances and Electronics
Many home and commercial appliances utilize rivets in their casing and assembly. Ovens, refrigerators, washers, dryers, and HVAC equipment rely on rivets to fasten sheet metal housings without penetrating interior compartments. Electronics like computers, printers, and industrial control panels also use rivets to assemble the outer chassis. The joining process is fast, inexpensive, and conductive while allowing serviceability of internal electronics.
Building and Construction
Rivets have broad uses in building and construction for assembling and connecting structural and architectural components. In framed buildings, rivets connect steel I-beams, channels, and gusset plates in a moment-resisting frame. Bridges use rivets to join truss members, decks, railings, and more. Rivets also construct prefabricated metal buildings, sheds, and shelters. In architecture, rivets affix metal to structures as ornamentation. Other construction uses include securing HVAC ducting, piping, conduit, panels, and more.
Shipbuilding
Ship hulls and marine equipment rely extensively on rivets for structural integrity. The watertight seals and vibration resistance provided by rivets are crucial in boat construction. Riveting assembles nearly all parts of the vessel from the internal framing to the outer skin. Portholes, railings, masts, and other fittings are also riveted in place. Riveting remains a trusted fastening method in naval engineering for its strength, durability, and corrosion resistance in ocean environments.
Railroad Applications
Rivets have long been the preferred fastener for railroads. Traditional railroad ties were sawn lumber riveted to steel rails. Modern ties are often precast concrete attached to the rails with large steel rivets. Rivets also assemble the steel in railroad bridges, trestles, signals, shops, and maintenance buildings. On locomotives and rail cars, rivets withstand the vibrations and impacts from traveling on tracks. Riveting is still common despite some welding use due to its reliability and ease of inspection.
General Manufacturing
Beyond these major industries, rivets have countless uses in general manufacturing and fabrication. They assemble cranes, rigs, fences, scaffolds, tanks, cabinets, racks, gears, valves, and more. Rivets join sheet metal fabrications like enclosures, guards, covers, and panels. They also attach castings, forgings, and injection molded parts made of metal or plastic. Any application that requires an inexpensive but robust mechanical fastening method is a candidate for rivets.
Types of Rivets
There are various types of rivets designed to meet different performance requirements. Some of the most common rivet varieties include:
- Solid/Drive Rivets - The original rivet style with a pre-formed head. They are installed by upsetting the tail.
- Blind Rivets - Have a built-in mandrel that is pulled to deform the rivet in a blind hole.
- Pop Rivets - Similar to blind rivets but faster to install with a rivet gun.
- Split Rivets - Have a split shaft that causes the rivet to flare outward as it is drawn into place.
- Compression Rivets - For softer materials, compressed and deformed during installation.
- Drive Screw Rivets - Combine threads with rivets for bolting into plastics.
- Structural Rivets - Large rivets crafted from high-strength alloy steel.
- Self-Piercing Rivets - Can pierce and clinch sheets in a single operation.
- Multi-Grip Rivets - Accommodate wider grip length variation between materials.
Rivet Material Selection
Rivets come in a range of materials that gives designers flexibility in strength, corrosion resistance, temperature range, and cost:
- Aluminum - Lightweight, general purpose rivets. Easy to cut and deform.
- Steel - Strong but heavy rivets. Low cost. Prone to corrosion.
- Stainless Steel - Excellent corrosion resistance for harsh environments.
- Copper - Used for electrical conductivity and aesthetics.
- Monel - Nickel-copper alloy with strength and corrosion resistance.
- Titanium - Extremely strong but expensive rivets. Used in aerospace.
- Plastic - Low cost rivets for light duty fastening of plastics and composites.
Rivet Joint Design Considerations
Properly designing riveted joints is crucial for structural integrity. Factors like material thickness, hole size, and rivet spacing must be optimized. Too few rivets or undersized rivets lead to joint failure. General design rules include:
- Rivets should be at least 3x the sheet thickness from a sheet edge.
- Rivet spacing should be 6-8x the rivet diameter between rivets.
- Holes should be 1/16" oversize for steel rivets or 1/32" for aluminum.
- Use sufficient rivets to match structural load demands.
- Use staggered rivet patterns to distribute load.
- Add washers under rivet heads for bearing surface.
- Clamp materials before drilling holes to prevent shift.
Riveting remains one of the simplest, most reliable, and cost-effective joining methods available for engineers. As shown by its broad use across industries, rivets will continue playing a key role in manufacturing and construction for the foreseeable future. Their versatility, ease of inspection, and mechanical strength make rivets the fastener of choice for numerous critical applications. CNC Milling CNC Machining
