When the bulge pushes against the back of the panel, it creates a clamping force to grip the sheet. When the power tool is activated, the mandrel spins quickly to pull the threaded portion of the shank toward the blind side of the workpiece to form a bulge around the unthreaded portion. “Spin-spin” tool: The rivet nut is threaded onto the mandrel on the pneumatic power tool and then inserted into a hole on the workpiece.
Rivet nut installation install#
But for individual use, you can install rivet nuts using easy-to-operate and lightweight hand tools or air/hydraulic setting tools. Because rivet nuts are made to be automated and used in factory settings, power installation tools are often mounted to a six-axis robot.
Some other industries and applications:Īmong the primary benefits of rivet nuts are that they offer a faster assembly and lower installation costs compared to other fasteners.
Rivet nuts are also perfect for every stage of production with no reworking needed after insertion-even when the workpiece has already been coated or painted. These fasteners are designed to be automated and are used widely throughout the automotive industry to attach items to dashboards, as well as in the chassis and bodywork to connect roof racks, spoilers, plastic fenders, radiators, and more. Perfect for your industry and application. Many times, installing rivet nuts is just more practical in comparison to other available fasteners. In fact, rivet nuts are not impaired by heat, unlike other fasteners such as weld nuts. Made from aluminum, stainless steel, steel, brass, and Monel, rivet nuts offer a variety of benefits over bolts, self-tapping screws, and pressed inserts. Additionally, because of their wide grip range tolerance, rivet nuts can be installed into a variety of material thicknesses. Rivet nuts are easy-to-install, reliable fasteners that can provide strong load-bearing threads into weak or thin gauge materials such as castings, housings, panels, tubes, and extrusions. If you’re not sure what kind of rivet nut you need for your application, seek out a fastener expert so all necessary project variables are met. Thin or thick wall: Whereas thick wall rivet nuts (also known as standard style) offer keyed heads, thin wall rivet nuts do not.Open or closed: Rivet nuts come in open- and closed-end styles, with the latter preventing water and dust getting into the assembly, such as with an automotive installation.Each style is meant to keep the fastener from turning at high torque levels, especially in softer materials. Shape: Rivet nuts come in splined, square, hexagonal, and the standard smooth, round cylindrical style.This feature is great for soft materials such as plastic, fiberglass, or aluminum. Wedge head: Wedges underneath the head keep the fastener from turning in the hole by “biting” into the mating material.Countersunk/low-profile head: With this feature, you ensure an installation that is nearly or completely flush.Thick flange: This feature can provide spacing and extra push-out strength.Wide front-side flange: This rivet nut feature offers a large load-bearing surface to both reinforce the hole and keep the rivet nut from being pushed through.Here are some features and styles to consider: So how do you know which to use? It depends on your application. The second is pulled into a sleeve and thus doesn’t bulge like the other type. There are two types of rivet nuts: The first is designed to form a bulge on the application’s blind side as the screw, pin, or bolt is tightened.
