Depending on the material, this formation of the head inside the material will often damage or enlarge the rivet hole and may simply pull the mandrel straight through the rivet body. The wide grip range capability permits design flexibility and reduced rivet inventory, which can result in substantial cost savings. If the rivet is too short, the blind head may not form fully before the mandrel breaks because the head is trying to form inside the material hole. The POP Multi-Grip blind rivet is a great solution to reduce the quantity of several sizes of standard rivets to one Multi-Grip blind rivet. Line up the holes you previously punched. Careful design will produce good fastenings. If youre using a hand-powered pop rivet tool, squeeze its trigger or lever slightly to put pressure on the mandrel and hold the rivet in place. POP Rivet Design Guidelines The success of any fastener depends on how well it's applied, and POP blind rivets are no exception. In this situation it is possible for the pieces to become loosely held together by the rivet, sort of like if a bolt is not tight. Insert the mandrel of the pop rivet into the front of the tool, pushing it in all the way so that the rivet body is all that sticks out. The numbered 'X rating' gives you a fair indication of the size rivets a particular gun can readily drive.
Futhermore, pop rivets are more likely to loosen under prolonged vibration. Do to the expansion of the rivet body this may hold the pieces together well enough if the loads are not high. Although pop rivets are easier to install, they are complex to manufacture and, as you might expect, are more expensive to use than the solid type rivets. If the rivet is too long, the mandrel will shear before the rivet has fully collapsed bringing the work pieces together. A rivet works by both expanding in width and shortening in length to mechanically bond to work pieces together. The rivet is designed to shear in that range when the force on the mandrel builds up. Aluminum rivets should never be used with. After mandrel breaks off domed head is left exposed. This particular rivet measuring ½ long would actually have grip range of 3/8. Used to join two materials together quickly. One rule of thumb is a rivets grip is about 1/8 shorter than its measured length. Blind rivets have a certain working depth (length). 5050 Aluminium Domed Head Steel Button Blind Rivets Nut Colored 414mm Pop Rivet Sizes with High Quality Head. 1/4' or 8 ( Rivet Sizing Chart) Domed head rivets are used when there is no access to the blind side of the two materials.
