![]() ![]() They may also retain the end of the mandrel within the rivet body when set for added strength.Ĭlosed End Rivets have a cup-shaped end that forms a tight seal against the bonded materials and captures the end of the mandrel within the rivet body for added strength. The mandrel breaks near the blind-side head and has flanges or countersunk heads for use in thin-gauge metals and low-strength materials. Open End Rivets are designed for a wide range of applications and are the most commonly used type of rivet. The two primary types of rivets are Open End and Closed End. ![]() Steel/Steel: Used with steel for high strength.Stainless/Steel: Also used with steel or aluminum for very high strength but is susceptible to rust and corrosion.Stainless/Stainless: Used with steel or aluminum for very high strength, and is not susceptible to rust and corrosion.Copper: Used for electrical conductivity.Aluminum/Steel: Similar to aluminum/aluminum but provides a higher strength.Aluminum/Aluminum: Used with aluminum or in applications susceptible to rust and corrosion.Below is a list of the common rivet material combinations and their respective uses: ![]() The type of material(s) that you are working on will help determine the type of rivet material that you choose. Material combinations refer to one material being used for the body and a different material being used for the mandrel. Once the tensile strength of the mandrel is reached, it will break off, leaving a secure and smooth installation. Some mandrels, like on a blind pop rivet, also retain a portion of the mandrel within the rivet body, providing a higher strength connection.Īutomotive rivets are offered in several types of materials and material combinations. The rounded end of the mandrel pulls in on the rivet body causing it to expand to the size of the hole that it is placed in, while also forming a tightly clinched load-bearing area on the rear side of the material. Squeeze the rivet gun to pull the rivet mandrel. Once in place, slide a rivet gun with the proper sized adapter over the rivet mandrel until the adapter is flush against the rivet body surface. To install, place the rivet body into a hole in the materials to be joined until the rivet body lip is flush against the material surface. Rivets consist of two parts: the rivet body (A) and the mandrel (B) – see image below. They also allow for different types of materials, such as steel and aluminum, to be easily attached to each other. The blind rivet style is popular because it is strong, secure, and access is only needed on one side of the materials that are being worked with. The two most common styles are Metal Blind Pop Rivets and Nylon Blind Pop Rivets. As you can probably imagine, there are a lot of different styles of rivets. They are also a good option when securing two finished materials such as painted surfaces. Automotive rivets can be used for structural repairs such as attaching a slip-on rocker panel over top of an existing rocker panel, mounting of plastic bumper covers and other accessories, or even specialized body repair work such as installing an aluminum bedside on a Ford F150. They can be used in automotive and non-automotive applications, but for this article we’re going to focus on automotive rivets. Rivets provide an effective way to fasten two materials together without welding, adhesives, or any specialty tools or skills.
