Nut Inserts: Common Uses and Installation Methods

Nut inserts, also commonly referred to as threaded inserts or rivet nuts, are specialized fasteners designed to create a strong, threaded hole in materials that might otherwise be too thin or soft to support a conventional bolt. With common use for sheet metal, plastics, wood, and other materials, one may wonder how these hardware components are installed and used. To answer such questions while aiding you in your search for the right fastening solutions, we will provide a brief overview of nut inserts.

Coming in numerous types, the basic design of a nut insert is a cylindrical fastener with internal threading that is placed into a pre-drilled hole in a material. Once installed, the insert provides a durable and reusable threaded hole that facilitates bolts or screws to be attached without causing any damage to surrounding materials. Typically made from metals like steel, stainless steel, or brass, nut inserts can withstand various environmental conditions and stresses, making them ideal for applications requiring high durability and strength.

As discussed before, the primary function of nut inserts is to provide secure threading in materials where conventional methods may not be effective. For example, the automotive industry makes great use of threaded inserts to secure components like dashboards and other interior fittings to the vehicle’s frame. In the aerospace sector, these fastening elements perform a similar role in attaching panels and other lightweight components to the aircraft structure. Alongside such examples, nut inserts are also commonplace in electronics, home appliances, and other assemblies where thin or brittle materials need threading to be established.

While the aforementioned benefit of protecting material integrity is the primary driver of nut insert popularity, there are still other benefits that make it an advantageous option for many applications. For example, their design allows for the easy assembly and disassembly of components while upholding the health and reliability of threading. Additionally, many inserts are resistant to vibration and loosening, ensuring that the connection remains secure in high-stress environments. As a last common benefit, nut inserts also provide even load distribution, mitigating the chance of damage or warping when subject to pressure.

Depending on the type of insert nut that one uses and the material being worked on, the exact method of installation may vary. For many insert nuts, press-fitting is a common practice, where a fastener is inserted into a pre-drilled hole and installed with a press. This is particularly useful for soft materials like plastic, where the insert may also feature knurled or ribbed exterior features to achieve additional grip. Self-tapping nuts are also a popular form of insert for wood and similar materials, featuring sharp threading that allows them to dig into a material without a pre-drilled hole required. While pressing and self-boring for insulation is quite common for these fasteners, more specialized options like rivet nuts will need special tools to draw in a shank that expands and locks the fastener in place.

With the ability to create threading in weaker, thinner, or more brittle materials, nut inserts of varying types can be a very advantageous solution for many projects and applications.
