Step 2: Use the table below to determine the length of the blind rivet. The grip range corresponds to the total thickness of the materials being joined together. Link to the Rapid range of standard blind rivets Choosing the right size of blind rivet Standard blind rivets are versatile and provide reliable results for everyday projects. Link to the Rapid range of XL blind rivets Standard blind rivets They are good for joining soft materials such as leather, rubber and plastic with hard materials. XL blind rivets have an extra-large head that provides a larger surface area for fastening and extra resistance. Link to the Rapid range of coloured blind rivets XL blind rivets They can be matched to the colour of the vehicle to conceal them. Link to the Rapid range of High-Performance blind rivetsĬoloured blind rivets are specially adapted for attaching number plates and other accessories to vehicles. They are good for attaching signs, joining sheet materials and for various repairs. High performance blind rivets have a wide range of applications with a sustainable result. They are well suited for fixing and repairing guttering or assembling shower panels, for example. Waterproof blind rivets are made in one piece to prevent leakage between the composite materials. They usually last longer than the materials being joined together and are good outdoors, for example, to attach number plates or silencers to vehicles, or repairing rusty metal surfaces. Stainless blind rivets are made of ISO 304 grade stainless steel. So you need to find out what kind and what size of blind rivet you need. The blind rivet you choose depends on the environment in which it will be used, as well as the materials you will be working with. They are used to fix together hard materials such as sheet metal and metal objects when you have access to only one side of the material – for example, when you fit mudguards on your car or gutters on your house. Where a flush surface is required, the countersunk head style should be selected.Blind rivets and blind riveting pliers are also called pop rivets and pop riveters. However, when soft or brittle materials are fastened to a rigid backing member, the large flange head should be considered because it offers twice the bearing surface. The low-profile domed head is appropriate for most applications. As a rule, the rivet materials should have the same physical and mechanical properties as the materials to be fastened, because a marked dissimilarity may cause joint failure due either to material fatigue or galvanic corrosion. Nature of materialsīoth the rivet and the materials to be fastened will affect the ultimate joint strength. Remember that insufficient rivet length will not allow proper formation of the secondary head at the back of the work. You must select a rivet with a grip range that includes the work thickness required. This determines the required "grip" of the rivet you select. Measure the total thickness of the materials to be joined. POP ® brand rivets are not certified for structural aerospace applications and such use is not recommended. Then refer to the "Shear" and "Tensile" in the Rivet Selection Guide on the product and select a POP ® brand rivet that provides the values required. These are functions of total joint strength, fastener spacing, rivet body material, and rivet diameter. Joint strengthįirst determine the single-joint tensile and shear values required for the application. The load applied to a fastener along its length. The load applied to a fastener along the joint interface. The recommended thickness range over which the body length will consistently provide a proper setting in a hole of the specified diameter. (Best practice is to follow the hole size recommendations provided).Īvoid burrs in and around the holes. It may also cause bulging or separation of the members by allowing the rivet to expand between them instead of only on the blind side. Too large a hole will reduce the shear and tensile strengths. Too small a hole will, of course, make rivet insertion difficult. Hole size can be important in blind riveting. This illustration provides a graphic representation of the POP ® blind rivet selection factors described below.
