A Large Flange Rivet is also sometimes called an Oversize Rivet, Large Flange Pop Rivets, or simply Flange Rivets. This type of rivet has a larger head, allowing the load to be spread over a larger load-bearing area, making Large Flange Rivets a good choice for use with softer materials.
What does a rivet look like?
It has a head, a smooth cylindrical body, and a tail that looks more like a metallic pin. Rivets are usually made of aluminum or steel, but there are some made with other materials. These types of fasteners are not tightened like the usual bolt and nuts.
What is a flare rivet?
These splits cause the shaft to fold and flare out (similar to the wings on a toggle bolt's nut) as the mandrel is drawn into the rivet. This flare (or flange) provides a wide bearing surface that reduces the chance of rivet pull-out. This design is ideal for high vibration applications where the back surface is inaccessible.
What are rivets used for in construction?
Use for covering irregular holes as well as extra holding power when fastening soft, thin materials to a rigid backing. Made of aluminum, rivets are lightweight, nonmagnetic, and have good corrosion resistance. They join material when you only have access to one side. The low-profile domed head creates a finished appearance.
What is a pop rivet?
A pop rivet is also known as a blind or hollow rivet and is used where you are only able to work with one side of the rivet. A special pop rivet gun or tool pulls the mandrel head into the body of the rivet, which then expands against the blind side of the join.

What is a Pop Rivet and How Does it Work?
A pop rivet is also known as a blind or hollow rivet and is used where you are only able to work with one side of the rivet. A special pop rivet gun or tool pulls the mandrel head into the body of the rivet, which then expands against the blind side of the join. Once it meets the face of the join’s blind side the mandrel snaps, causing the stem to eject to create a tight joint. A pop rivet can be used as a replacement for nuts and bolts, screws, welds and adhesives.

How does a rivet deform?
The rivet is deformed by pounding or smashing of the tail, which makes the material flatter and usually causes the tail to be expanded by about one and a half times the size of the stem's original diameter.
Do self piercing rivets need a hole?
Self-piercing rivets – These rivets do not need a drill or punched hole as the end includes a chamfered poke to pierce materials to be joined. Self-piercing rivets go through the top sheet of material but do not fully pierce the bottom sheet, creating a water or gas-tight joint.
How does a rivet work?
On installation, the rivet is placed in a punched or drilled hole, and the tail is upset, or bucked (i.e., deformed), so that it expands to about 1.5 times the original shaft diameter, holding the rivet in place.
How to upset a rivet?
Rivets may also be upset by hand, using a ball-peen hammer. The head is placed in a special hole made to accommodate it, known as a rivet-set. The hammer is applied to the buck-tail of the rivet, rolling an edge so that it is flush against the material.
What is a universal head rivet?
A typical technical drawing of a universal head solid rivet. Solid rivets are one of the oldest and most reliable types of fasteners, having been found in archaeological findings dating back to the Bronze Age. Solid rivets consist simply of a shaft and head that are deformed with a hammer or rivet gun.
How to buck a rivet?
Rivets small enough and soft enough are often bucked. In this process the installer places a rivet gun against the factory head and holds a bucking bar against the tail or a hard working surface. The bucking bar is a specially shaped solid block of metal. The rivet gun provides a series of high-impulse forces that upsets and work hardens the tail of the rivet between the work and the inertia of the bucking bar. Rivets that are large or hard may be more easily installed by squeezing instead. In this process a tool in contact with each end of the rivet clinches to deform the rivet.
What is semi tubular rivet?
Semi-tubular rivets (also known as tubular rivets) are similar to solid rivets, except they have a partial hole (opposite the head) at the tip. The purpose of this hole is to reduce the amount of force needed for application by rolling the tubular portion outward. The force needed to apply a semitubular rivet is about 1/4 of the amount needed to apply a solid rivet. Tubular rivets are sometimes preferred for pivot points (a joint where movement is desired) since the swelling of the rivet is only at the tail. The type of equipment used to apply semi-tubular rivets range from prototyping tools to fully automated systems. Typical installation tools (from lowest to highest price) are hand set, manual squeezer, pneumatic squeezer, kick press, impact riveter, and finally PLC-controlled robotics. The most common machine is the impact riveter and the most common use of semitubular rivets is in lighting, brakes, ladders, binders, HVAC duct work, mechanical products, and electronics. They are offered from 1/16-inch (1.6 mm) to 3/8-inch (9.5 mm) in diameter (other sizes are considered highly special) and can be up to 8 inches (203 mm) long. A wide variety of materials and platings are available, most common base metals are steel, brass, copper, stainless, aluminum and most common platings are zinc, nickel, brass, tin. Tubular rivets are normally waxed to facilitate proper assembly. An installed tubular rivet has a head on one side, with a rolled over and exposed shallow blind hole on the other.
Why are rivets not heat treated?
Such riveted structures may be insufficient to resist seismic loading from earthquakes if the structure was not engineered for such forces, a common problem of older steel bridges. This is because a hot rivet cannot be properly heat treated to add strength and hardness. In the seismic retrofit of such structures it is common practice to remove critical rivets with an oxygen torch, precision ream the hole, then insert a machined and heat treated bolt.
How big of a hole should a rivet be?
To become a proper fastener, a rivet should be placed in hole ideally 4–6 thousandths of an inch larger in diameter. This allows the rivet to be easily and fully inserted, then setting allows the rivet to expand, tightly filling the gap and maximizing strength.
What is a threaded flange?

Overview
Types
There are a number of types of rivets, designed to meet different cost, accessibility, and strength requirements:
Solid rivets are one of the oldest and most reliable types of fasteners, having been found in archaeological findings dating back to the Bronze Age. Solid rivets consist simply of a shaft and head that are deformed with a hammer or rivet gun. …
History
Rivet holes have been found in Egyptian spearheads dating back to the Naqada culture of between 4400 and 3000 B.C . Archeologists have also uncovered many Bronze Age swords and daggers with rivet holes where the handles would have been. The rivets themselves were essentially short rods of metal, which metalworkers hammered into a pre-drilled hole on one side and deformed on the other to hold them in place.
Sizes
Rivets come in both inch series and metric series:
• Imperial units (fractions of inches) with diameters such as 1/8" or 5/16".
• Système international or SI units with diameters such as 3 mm, 8 mm.
The main official standards relate more to technical parameters such as ultim…
Applications
Before welding techniques and bolted joints were developed, metal framed buildings and structures such as the Eiffel Tower, Shukhov Tower and the Sydney Harbour Bridge were generally held together by riveting, as were automobile chassis. Riveting is still widely used in applications where light weight and high strength are critical, such as in an aircraft. Many sheet-metal alloys are prefera…
Joint analysis
The stress and shear in a rivet is analyzed like a bolted joint. However, it is not wise to combine rivets with bolts and screws in the same joint. Rivets fill the hole where they are installed to establish a very tight fit (often called interference fit). It is difficult or impossible to obtain such a tight fit with other fasteners. The result is that rivets in the same joint with loose fasteners carry more of the load—they are effectively more stiff. The rivet can then fail before it can redistribute …
Installation
There are several methods for installing solid rivets.
• Manual with hammer and handset or bucking bar
• Pneumatic hammers
• Handheld squeezers
• Riveting machines
Testing
A hammer is also used to "ring" an installed rivet, as a non-destructive test for tightness and imperfections. The inspector taps the head (usually the factory head) of the rivet with the hammer while touching the rivet and base plate lightly with the other hand and judges the quality of the audibly returned sound and the feel of the sound traveling through the metal to the operator's fingers. A rivet tightly set in its hole returns a clean and clear ring, while a loose rivet produces a …
