Rivets are one of the most ubiquitous and versatile mechanical fasteners used in manufacturing and construction. A rivet is a type of fastener that is inserted through holes in two or more materials, and then mechanically deformed on one or both ends to clamp them together. The deformation on the ends of the rivet is called the shophead and bucktail.
Rivets have been used for thousands of years, dating back to the Bronze Age. Originally made of bronze, copper, iron or other metals, modern rivets are commonly made of aluminum, steel, stainless steel, copper and titanium. Rivets come in a wide variety of shapes, sizes and materials to accommodate many different applications and types of materials being joined.
Some of the many uses and applications for rivets include:
Aircraft and Aerospace
Rivets are extensively used in aircraft and aerospace applications to assemble the frame and attach the outer ‘skin’ to it. Rivets in aircraft are typically flush head rivets that provide a smooth aerodynamic surface. They are installed by professional riveters using pneumatic riveting guns and form perfectly matched finished heads. Aircraft-grade rivets are made of lightweight materials like aluminum, titanium and specialty alloys. Using rivets instead of welding provides a lighter structure and avoids potential structural weaknesses caused by welding.
Rivets play an important role in automobile manufacturing to assemble body panels and other components. Riveting provides a strong, reliable and vibration-resistant joining method that can withstand the rigors of driving. Self-piercing rivets (SPR) are commonly used because they can pierce directly through panels without pre-drilled holes. Rivets are also resistance spot welded to the body frame during unibody construction. Using a combination of rivets and adhesives creates automotive joints that are lightweight yet capable of withstanding crumple zones.
Many household appliances rely on rivets for assembly and durability. The outer shells of washing machines, dryers, refrigerators, dish washers and ovens are commonly held together with rivets. They allow the sheet metal housing to be perforated while maintaining structural integrity. The vibrations generated by motors and moving components require the robustness of rivets to avoid loosening. Self-locking rivets that resist vibration loosening are ideal for appliances.
Small electronics like computers, cell phones and medical devices have small, precise components that are often riveted. Cold heading and semitubular rivets are well-suited for attaching circuit boards, heat sinks and delicate parts. Electronics enclosures and cases also use rivets for clean and secure assembly. When assembled correctly, the rivet head becomes hidden within the unit for aesthetics and safety.
HVAC Systems
The extensive ductwork involved with HVAC (heating, ventilation and air conditioning) systems often utilizes rivets for fastening and sealing sheet metal joints. Ducts have many seams and attachments that must withstand vibration and air pressure changes while remaining air-tight. The joining process is fast and inexpensive with rivets. They also allow ducts to be disassembled for maintenance if needed. Self-sealing rivets are common for HVAC applications because they instantaneously seal upon installation.
Rivets serve an important function in plumbing systems by providing leak-proof joints between pipes, valves and fixtures. The seals must withstand continuous water pressure changes from surges. Large diameter rivets are ideal for joining pipes, tubes and hoses throughout residential and commercial plumbing. Rivet strength integrity prevents leaks within the wall cavities and behind sinks where access is impossible.
Gutters and Downspouts
Seam rivets are commonly used to assemble and attach metal gutters and downspouts on homes and buildings. The continuous seams formed with rivets prevent leaks throughout the gutter system. They are also useful for fastening gutter hangars along the roof eaves. Rivets provide a faster and easier way to install gutters compared to caulking or using adhesives. The joints will remain leak-proof for the life of the gutter.
Building and Construction
Rivets are ubiquitous in many facets of building and construction. Some examples include:
- Metal roofing relies on rivets to attach panels and trims while maintaining water-tightness. Roof seam rivets flexibly withstand expansion and contraction from temperature swings.
- Steel I-beams, columns, studs and joists are joined together with high strength structural rivets. They are fastened on-site for rapid construction.
- Façade panels, light fixtures, railings, stairs, ramps and walkways are assembled and erected using rivets.
- Insulation anchors, electrical conduit straps, HVAC ductwork, suspended ceiling grids and fire sprinklers are secured with rivets.
- Storage tanks, silos, metal buildings and cargo containers are riveted for durability through harsh conditions.
Rivets have long been used in the construction of bridges because of their structural integrity. The riveted connections throughout trusses, girders, decking and guardrails handle heavy dynamic loads from traffic. Rivets also withstand the corrosive effects of water in humid environments. Using rivets instead of bolts or welds speeds up the construction process and reduces costs. Riveted connections outperform welds because they flex rather than cracking under load.
Ships and Boats
Shipbuilding has relied on rivets for centuries to assemble robust hulls capable of handling open ocean voyages. The riveted seams between steel plates on ships must be water-tight to avoid flooding. Rows of heavy duty rivets are also used on the flanges for propeller shafts. Boats, barges, tankers and submarines are still predominantly held together by rivets due to their strength and reliability.
Rivets have long been the preferred fastener for assembling railroad tracks. The baseplates, joints, rail alignment and attachments for wood, concrete and steel sleepers are all connected with rivets. Vibrations from locomotives and cars exert tremendous forces which rivets are uniquely suited for. Riveting track components provides consistent structural integrity that resists cracking.
Industrial Machinery
Heavy machinery used in agriculture, mining, oil & gas, forestry, construction and other industries all use rivets at stress points. Large gearboxes, driveshafts, booms, lifts and presses rely on rivets to handle shock loads and vibration. The main frames, access platforms, ladders and controls are also riveted. Industries prefer rivets over welding because they allow future disassembly for repair if required.
Playground Equipment
Swing sets, jungle gyms, slides and other playground equipment often use rivets for durability and safety. The sheet metal and tubes that make up recreational structures undergo substantial movements and forces from kids at play. Using solid and semitubular rivets prevents loose parts that could pinch fingers. Riveting allows manufacturers to perforate components while maintaining structural integrity under load.
Rivets serve both a functional and decorative role in furniture. Sheet metal chairs, tables, shelving, cabinets and lockers are frequently held together with rivets. They allow flat materials to be bent into useful shapes and forms. Rivets provide concealed fastening points for strength without compromising style and aesthetics. Decoratively capped rivets are also extensively used to embellish furniture with an industrial flair.
In summary, rivets are one of the most versatile mechanical fasteners used across countless industries. The unique properties of rivets enable materials to be joined securely while allowing flexing and movement. Technological advancements in materials and installation processes continue to expand the applications and performance capabilities of rivets as a strong, reliable fastening method. Their versatility ensures rivets will continue playing a critical role in manufacturing and construction for the foreseeable future. CNC Milling CNC Machining
