Threaded inserts consist of a coarse wooden screw thread on the outside and a fine machine screw thread on the inside. This design makes it easy to use machine screws in wood, as well as makes them easy to remove. To better understand these compact devices, this blog will provide a brief overview of threaded inserts and their importance.
Each time a traditional wood screw is removed, it damages the thread it cut into the wood, rendering the thread useless. To avoid this, a threaded insert can be used. Threaded inserts are usually utilized when the object in which a threaded fastener is being installed to is made of a soft material, helping to avoid any damage to the material. Moreover, the threaded insert can be placed inside the object after the threaded fasteners have been driven into the insert.
Additionally, threaded inserts can be used when an object is too thin to support the entire length of a
threaded fastener. In some cases, the threaded insert may poke out of the back of the object, but a screw or bolt can still be driven all the way in. Like other fastening components, threaded inserts are available in varying designs, allowing them to be used in a wide-range of applications.
All threaded inserts are manufactured with female threading to support the use of fasteners that contain male threading, each featuring a unique design. For example, helical threaded inserts consist of a coiled design that is composed of steel or bronze. The metal is typically coiled up to the precise size and shape to assist the threaded fastener.
Furthermore, there are also captive nut inserts, those of which have a nut wrapped around female threading. Also referred to as cage nuts, captive nut inserts feature “wings” on the top that dig into the object when a threaded fastener is driven into them. This type of insert has been around for over 50 years, and has been widely used for a number of applications, such as wall-mounting tasks.
The last type is an externally threaded insert which is designed with threading on its exterior. Though it still has internal threading, its external threading is its defining characteristic, allowing it to be driven into pilot holes with ease. Though threaded inserts are incredibly helpful devices, they need to be used with precision to ensure that they are properly installed and working optimally.
