Pneumatic and hydropneumatic hand tools are one option. Tools for Solid Rivetsīecause solid rivets are squeezed or crushed, instead of struck, the machines for setting them are known as compression riveters or rivet squeezers.

Each arm consists of 10 1-inch-thick steel plates that are riveted together.”Ī pneumatic compression riveter installs a semitubular rivet in the housing for an industrial Venturi fan. “We’ve even supplied custom equipment to rivet the arms that lift the big ladles carrying molten steel in a steel mill. “We’ve supplied riveting equipment for the M60 machine gun, jail cell doors and the Brooklyn Bridge,” says Arthur. Solid rivets fasten the roof, sidewalls and floor rails of semitrailers. Solid rivets can be found in the frame, transmission mounts and shock mounts of a car, and hundreds of thousands of them are used to assemble the frame of an airplane. Solid rivets are used for high-reliability structural applications in products such as trucks, buses, boats, missiles, military vehicles, bicycles, metal furniture, ladders and electrical cabinets. “In many cases, you’re trying to make the rivet look and feel like the parts it’s assembling, as if the parts have not been penetrated,” Arthur explains.
It also expands the shaft so it completely fills the hole. The riveting process does more than just bring the parts together and form a head on the rivet. A small aluminum rivet-0.0937 to 0.25 inch in diameter-can be set in a fraction of a second, while a large steel rivet-0.25 to 0.375 inch in diameter-might take 1 to 3 seconds, says Robert Arthur, vice president of Michigan Pneumatic Tool Inc. Just how slow depends on the tool, the rivet material, the shank diameter and how much force is applied. However, instead of a single, rapid strike, a solid rivet is upset with a slow, controlled squeeze. They are available with many head styles, including round, flat, countersunk, pan, truss, universal, brazier, acorn and mushroom.Īs with tubular and semitubular rivets, access to both sides of the assembly is necessary to set solid rivets. Shank diameters range from 0.062 to 1.75 inches, while head diameters range from 0.122 to 2.844 inches. Solid rivets can be made from steel, stainless steel, brass, copper, Monel, Inconel, titanium and aluminum. It’s a solid shaft with a cold-formed head. Unlike tubular, semitubular and blind rivets, a solid rivet doesn’t have a hollow section that makes it easy to upset. Solid rivets require a different approach. The riveter grips the mandrel and pulls it through the rivet body, causing the body to expand and forcing the materials together.
In contrast, a blind rivet consists of a headed, hollow rivet body and a headed, solid mandrel, or tail. As the name implies, an impact riveter upsets the rivet with one quick, powerful blow from the ram. Tubular and semitubular rivets are typically installed with a pedestal-mounted impact riveter. Sometimes, a good, hard squeeze is better than a rap on the head or a pull on the tail-at least for installing certain kinds of rivets.
