Rivets are a versatile fastening technology that have been used for centuries in manufacturing and construction. A rivet is a mechanical fastener that consists of two main parts - a smooth cylindrical shaft and a head. The shaft is inserted into pre-drilled holes in the materials being joined and the head is upset, or mushroomed out, to clamp the materials together. There are many advantages to using rivets over other types of fasteners.
In manufacturing, rivets are commonly used to assemble parts and products made from metal, plastic, fiberglass and other rigid materials. The aircraft and aerospace industries have historically been major users of rivets for airframe assembly. Thousands of rivets hold together the aluminum alloy skins and structural components in both civilian and military aircraft. Rivets allow for strong, permanent and reliable joints while adding little weight. They are also relatively inexpensive and easy to install. Other manufacturing applications include appliances, electronics, vehicles, furniture and industrial machinery. Rivets provide reliable mechanical fastening where welding, soldering or adhesives are impractical.
The main advantages of rivets for manufacturing are:
- High clamping strength and resistance to shock and vibration
- Consistent and uniform fastening method
- Installation requires access to only one side of a component
- Minimal surface preparation needed compared to welding or adhesives
- Joints can handle some movement from expansion, contraction or distortion
- Low per-unit cost compared to other permanent fasteners
- Proven reliability from decades of successful use
For mechanical design engineers, rivets provide known, quantifiable properties that allow for calculation of joint strength and reliability. The grip range, shear strength and other specifications can be selected to suit the application. Standardization also allows faster design and assembly using existing tooling and inventory. While not appropriate for every situation, rivets solve many common fastening challenges.
In construction, both structural and non-structural riveting provide robust connections for steel buildings, bridges, cranes and towers. Structural rivets must transfer tension and shear forces between beams, gussets and frames. Large diameter rivets up to 1 inch are commonly used in high-load locations. Non-structural rivets securely fasten exterior panels, siding, roof decks and interior components like ducting and electrical enclosures. The installation process is similar to manufacturing - holes are drilled or punched and the rivets are mechanically driven using manual, pneumatic or hydraulic tools.
For construction projects, rivets offer:
- High tensile strength with good vibration and fatigue resistance
- Consistent, code-approved structural properties
- Visible inspection capability over the life of the structure
- Ease of installation compared to bolts or welds
- Low sensitivity to adverse weather during construction
- Corrosion resistance for long service life
- Cost competitiveness with other structural fasteners
Rivets make economic sense for many construction jobs thanks to their combination of strength, reliability, ease of use and low installed cost. The upfront investment in riveting tools and equipment is quickly repaid through faster installation times compared to drilling and tapping bolted connections. For the builder, this translates into lower overall labor expenses.
While loosely related to nails, rivets are significantly different in design and function. Nails rely entirely on friction to resist withdrawal from the substrate. They have no clamping force and minimal shear strength. Rivets develop clamp load during installation and maintain it indefinitely afterwards. The mushroomed head interlocks the joined materials even as they shift due to loading. Rivet joints are therefore much stronger and more secure than nailed connections.
Construction and manufacturing have relied upon rivet technology for well over a century. Newer fastening methods like structural adhesives and welded studs have taken over some applications, but rivets remain a tried and true method. Their versatility, strength, ease of inspection and low installed cost ensure rivets will continue playing a key role in assembly and construction for the foreseeable future. With an understanding of their advantages, engineers and builders can effectively incorporate rivets into designs ranging from delicate electronics to massive bridges. Rivets deliver reliable, economical and long-lasting fastening performance across countless applications. CNC Milling
