6/22/2023 0 Comments Metal rivetBlind rivet (pop rivet)īlind rivets (Figure 1) are suitable when one side of the joint cannot be seen or accessed. Split rivets are commonly used in basic repair works at home, and they are not used in critical applications. The rivet has a sharp end, and the added surface area keeps the rivet from pulling back through softer materials such as leather, wood, and plastic. Split rivetĪ split rivet (Figure 3 labeled B) has a divided shaft to create more surface area after it has been passed through the joint. The tail of a solid rivet is deformed using a rivet gun or hammer to keep it in place. Solid rivetĪ solid rivet (Figure 3 labeled A) consists of a solid shaft with a head at one end. Here are some of the different kinds of rivets and how they work. Different types of rivetsĪ large variety of rivets is available due to the many different materials that need joining. But, contrary to welded connections, rivets resist vibrations and secure joints better.įigure 2: Using a rivet gun for riveting aluminum parts together. Rivets are designed for permanent joints similar to welding or structural adhesives. The rivet shaft prevents any radial movements. The permanently formed heads at both ends prevent the rivet from detaching from the drilled hole. The original head of the rivet is called the ‘factory head,’ and the deformed end is called the ‘buck-tail.’Ī rivet can support tension on each end of the structure. The deformation smashes the tail, making it flatter, resulting in a dumbbell-shaped rivet. The tail then expands to around 1.5 times the original diameter of the shaft, holding the rivet in place between both materials. The tail is then upset or bucked (deformed) by mechanical force using a hammer or rivet gun. The rivet is inserted between both holes. How do rivets work?įirst, a hole is drilled or punched in the materials to be connected. The mandrel allows the riveter to deform the tail of the rivet without striking it directly. The shafts are hollow with another internal piece called a mandrel. Rivets are used to join large structural pieces and small electronic assemblies. The tapered end of the shaft is called the rivet’s tail. A rivet consists of a head at one end and a cylindrical body at the other end, called its shaft. They are especially suited for restricting delicate, thin materials and generally fragile connections.View our online selection of pneumatic rivet guns!Ī rivet is a popular mechanical fastener to join two or more materials. These solid fasteners resist water, vibration, tampering, and other severe conditions.Threaded insert and rivet nuts which are applied like a classic rivet integrate seamless, strong, and permanent threading in fragile sheet materialsWhere can be Rivets used?Rivets are intended to offer awesome flexibility, enabling them to fasten wood, metal, plastic and substantially more. They can be installed from only one side making them ideal for areas where access is limited.Tubular Rivets have a shank hole within the shaft of the rivet and are available with different head styles such as the oval, button, flat and countersunk.Snap Rivets are supplied pre-assembled and simply push into the required holes providing a fast and neat solution.Solid rivets, or the original rivet. They are used to permanently join two steel, aluminium or copper plates usually in mechanical applications where it is imperative that joints do not become loose and cause failure.Types of rivetsThere are many types of rivets available:Blind Rivets also known as drive rivets have a mandrel through their centre that once inserted into pre-drilled holes of the parts they are joining, the blind end expands and the mandrel snaps off. On the installation, a riveter places a rivet in a pre-drilled hole, and the tail is set or bucked (i.e., deformed) with a rivet gun, rivet tool or pneumatic hammer so that it expands to about 1.5 - 2 times the original shaft diameter, holding the rivet in place. Rivets Rivets are mechanical fasteners that consist of a smooth cylindrical shaft with a head on one end and a tail at the opposite end.
