Threaded Inserts and Threaded Insert Riveters

A threaded insert, or threaded bushing, is a fastener component that may be installed in the surface of a component for the means of establishing a threaded hole. While threaded inserts may commonly be used for threaded hole repair, they may also increase the durability of softer materials, enable holes to be established in thin materials, avoid machining requirements, or be used to shift between unified and metric threads. In order to optimally install such components, a tool known as a threaded insert riveter is commonly used.

Threaded inserts may come in a variety of forms, including types such as the rivet nut, captive nut, helical insert, potted insert, and pressfit bushing. The choice between each fastener will typically depend upon the application in question, varying on the material that the threaded insert is installed in, whether or not the finished assembly is a ready-to-assemble item, and other factors. It is also important to consider the strength factor of threaded inserts before making a decision, as pull-out and torque-out are both parameters that may affect health and efficiency. Generally, pull-out refers to the amount of force needed to rip the insert out of the material it is installed in, while torque-out is the maximum amount of torque for turning the fastener without inducing a clamp load. 

Just as there are multiple types of threaded inserts that one may use for an application, there are also various threaded insert riveters that one may procure as well. While manually threaded insert riveters are optimal for simplistic installations and may be hand operated with ease, such tools are best fit for conducting work only on a handful of threaded inserts. Powered tools, on the other hand, are much better for manufacturing processes and MRO procedures. Powered threaded insert riveters can come in three basic types, those of which are the spin-spin tool, spin-pull off tool, and pull-to-pressure tool.

The spin-spin type is a simplistic option, allowing for the threaded insert to be fitted onto the mandrel before drilling it into a pre-drilled hole. The rotation of the mandrel causes a bulge to be formed around the unthreaded portion of the fastener, eventually resulting in a full collapse. This ensures that the threaded insert is securely installed, and the mandrel can be reversed for removing the tool. The spin-pull off tool is similar to the spin-spin type, though features a preset bulge collapse to avoid the collapsing or cracking of the receiving material. The pull-to-pressure type utilizes a preset pressure rather than a preset length for the blindside bulge, making it a perfect fit for metals and hard plastics.

When more power is required for heavy-duty applications, pneumatic tools may be a beneficial option with their high power, performance, and speed. Despite this, they are often known for being loud while operating. Electric and battery-powered tools are also an option, the battery type providing high amounts of flexibility due to how it may be freely angled and operated. When choosing between each threaded insert riveter type, one should consider how they will use the tool, and whether or not portability and ease of use are major concerns. Some equipment may also be more optimal for working on certain materials over other types, thus there are many factors which can be used to determine what riveter is the best fit for a particular application.
