If you’re working on a project that requires fastening parts together, you’ve probably run across rivet types. Generally, they’re replaceable and have two parts – a head and a tail. The head is cylindrical, while the tail is semicircular with a heat-resistant, slightly down-shaped structure. Read on to learn more about types of rivets and how they are used. Then, you can choose the right one for your project.
Commonly used rivets
Solid rivets come in a variety of sizes and materials. Some of the most common materials are steel and concrete, while others include brass, bronze, copper, stainless steel, and aluminum. However, these materials do have some drawbacks. Because of their large volume of production, they often have lower tensile and fatigue strengths. Using solid rivets may cause cracking or loose assembly. But if you want to avoid the risks, you can use washers or thin bolts.
Materials
Metals used in rivets come in many varieties and strengths. For instance, stainless steel rivets with steel mandrels are among the strongest types of rivets. Aluminum rivets also work well in certain applications. Other types of rivets include tubular rivets, blind rivets, split rivets, and flush ones. Below are the common types and their properties. Read on to discover more about each type. Regardless of your application, there’s a type of rivet that works for you.
Sizes
There are several important differences between the various rivet types. The diameter of the rivet determines its effective grip range, while the grip length determines how thick the material can be. To determine the size of the fastener, you must first measure the diameter of the material and the mandrel or shaft of the rivet gun. The body diameter of a size 45 rivet measures 4/32 inches, while a size 68 rivet has a six/32-inch diameter and an eight-sixteen-inch grip length.
Applications
While there are several different kinds of rivets, they all share the same basic characteristics. Their strength, reliability, and moderate cost have made them popular fasteners for decades. While other types of fasteners have their benefits, rivets have a few key differences that make them a better choice for certain applications. For example, blindside rivets have a lower grip range and stick up when installed below the range. They also require more space on the back side and more blindside clearance. In addition, their design makes them less flexible than other types of fasteners.
Inspection
The process for evaluating rivet quality can be time-consuming and cumbersome if you don’t know what you’re looking for. An advanced NDT system like Eddyfi Technologies’ RIVETINSPECT can provide a rapid, reliable solution to inspecting rivet holes. This system can acquire more than 100,000 3-D point measurements per second and is rugged enough to handle tough environments and all kinds of stack materials. In addition, this system can also be used for general fastener hole inspection.
