Rivets are one of the most versatile and widely used fasteners in manufacturing and construction. A rivet is a mechanical fastener that connects two or more objects by inserted the rivet through holes in the parts to be joined and deforming the protruding ends. Rivets come in a variety of head shapes, materials and sizes for different applications. Here are some of the most common uses for rivets:
Aircraft and Aerospace Applications
Rivets are extensively used in aircraft and aerospace structures. Aircraft grade rivets are made from lightweight and high-strength materials like aluminum, titanium and specialty alloys. Rivets are preferred for aircraft assembly because they create smooth exterior surfaces crucial for aerodynamic efficiency. Riveted joints also allow for some flexibility to prevent fatigue cracking from vibration and turbulence during flight. From the fuselage to the wings and control surfaces, thousands of rivets hold together critical components in both civilian and military aircraft.
Metal Fabrication and Machinery
Rivets are a go-to fastener solution for fabricating metal parts and machinery. They are easy to install, create stiff joints and can accommodate some movement from vibration or thermal expansion. Rivets are commonly used to assemble sheet metal enclosures, frames, brackets, gears, pulleys and more. Pop rivets, with pre-inserted mandrels to be pulled during installation, are popular for assembling HVAC ductwork, electronic chassis and other sheet metal assemblies. Rivets also securely fasten metal parts to wood and composites.
Construction and Infrastructure
The versatility, strength and corrosion resistance of rivets make them ideal for construction projects and infrastructure. Aluminum and stainless steel rivets assemble rebar in concrete structures. Rivets connect steel I-beams and girders in bridges, towers, cranes and buildings. Utility poles, cell towers, billboards, roadway signage and railings all rely on rivets for sturdy, long-lasting connections. Rivets are also extensively used in the assembly of storage tanks, silos, shipping containers and prefabricated structures.
Automotive Manufacturing
Automotive manufacturing involves joining disparate materials like metals, plastics and composites, for which rivets are perfectly suited. Self-piercing rivets efficiently join high strength steel components in vehicle frames and bodies with few steps. Rivets provide durable fastening for attaching interior panels, trim pieces, seats and doors to the vehicle frame. Specialty large flange rivets help absorb crash impact energy. Exterior components like running boards and roof racks rely on weather-resistant rivets.
Appliances and Electronics
The mass production of appliances and electronic devices depends on rivets to quickly and reliably assemble their sheet metal housings. The joining flexibility of rivets also allows attachments of plastic and electronic components to metal frames. Rivets make serviceability easier by allowing panels to be removed and replaced when repairing appliances and electronics. Critical devices like medical equipment and aerospace electronics use specialty rivets tested for high strength, corrosion resistance and electrical conductivity.
Recreational Products
From bicycles to boats to camping gear, rivets assemble all types of recreational equipment which must withstand rugged use and outdoor exposure. Stainless steel and aluminum rivets withstand freshwater and saltwater corrosion in boats and marine hardware. Bicycle frames rely on rivets joining tubes and lugs securely enough for shock impacts and pedaling forces. Lightweight pop rivets assemble camping trailers and pop-up tent frames. Rivets also construct playground equipment, bleachers, gates, fencing and handrails.
Jewelry Crafting
Miniature rivets serve an important purpose in jewelry making. Small rivets act as hinge pins for lockets and fold-over bracelets to allow opening and closing. Rivets also provide sturdy but reversible fastening for necklaces, chokers, charm bracelets, brooches and more. This allows the wearer to change decorative elements when desired. Jewelry rivets come in materials like brass, copper, nickel silver and steel matching other components. Some decorative jewelry rivets feature gemstones or enamel coatings.
Understanding Rivet Material and Type Selection
With rivets serving such a wide array of uses, it is important to select the optimal rivet design and material for each application. Using the wrong rivet can lead to premature failure or make assembly difficult and time-consuming. Here are some key factors to consider:
- Strength – The rivet must withstand expected forces including tension, shear and vibration without bending, cracking or pulling out. Aircraft and structural applications require especially strong rivets.
- Ductility – More ductile materials like aluminum can deform during riveting to fill gaps, while brittle materials may crack under pressure. Ductility is crucial for rivets joining dissimilar, uneven or multi-layered stacks.
- Corrosion Resistance – Rivets used outdoors or in water applications require corrosion-resistant materials like stainless steel, aluminum, silicone bronzes or nickel alloys. Coatings and platings can improve corrosion protection.
- Temperature Resistance – Applications with high heat require rivets made from high-melting point materials that maintain strength like nickel, cobalt or titanium alloys. Low temperature uses need impact-resistant rivets.
- Fatigue Strength – Aircraft, auto and vibration-heavy applications need rivets that resist cracking from millions of load reversals without failing.
- Assembly Method – Does the application suit manual, pneumatic or specialty power riveting tools? This impacts rivet head styles and alloy selection.
- Appearance – Exposed rivets on finished products may require rivet heads to match the surrounding surfaces or incorporate decorative shapes.
With knowledge of these factors, manufacturers and builders can select optimal rivets or consult with suppliers to compare rivet design, material and cost tradeoffs. While often seen as mundane fasteners, rivets in fact enable assembly and enhance performance in countless critical, demanding and valuable products and structures. CNC Milling
