All About Threaded Inserts in the Lighting Industry

Threaded inserts have many valuable uses, especially when it comes to the lighting industry. This type of fastener element creates precise, durable internal threads that are able to withstand higher axial and radial loads compared with self-tapping screws.

There are several factors that will influence the performance of threaded inserts. If you decide to use them and which type to use will depend on the installation method, the material you are using, and what kind of insert support you are looking for.

FASTEKS® makes steel or stainless steel threaded inserts guaranteed to create precise, durable internal threads in workpieces made of light metal alloy and other materials with low shear resistance. They are self-tapping, simple to install and come in six different types, depending on your needs and what kind of project you are working on.

Threaded Inserts Types and Uses

The list below highlights each type and what kind of projects each one is best used for:

1. The TRISERT®, made out of brass, has a regular head and is used for thermoplastic materials. It has a larger contact surface and can be used in drilled or molded holes. It also has a higher torque and axial forces.
2. The TRISERT-3®, made out of steel, has a reduced head and is used for light metal and plastics. It can be used in drilled or molded holes. It offers faster installation due to a greater helix angle of the thread flanks, and has corrosion resistance of up to 720 hours to red rust.
3. The FOAMSERT®, made out of brass, can be either double ended for bidirectional purposes, or have a reduced head. This insert was designed especially for expanded material and wood, and it can be used in drilled or molded holes.
4. The MULTISERT®, made of brass, is un-headed and particularly suitable for thermoplastic materials. It has a special plain location spigot and has three installation options: press-fitting, ultrasonic insertion or heat insertion.
5. The MICROBARB®, made out of brass, is particularly suitable for thermoplastics and thin section materials. It’s used especially for applications in electronics and can be installed via press-fitting, ultrasonic insertion or heat insertion.
6. The HiMOULD®, made of brass, has an open or closed ended design and is used for thermoplastic and thermoset plastics. It is very thin-walled, particularly suitable for applications with low wall thickness. This insert is designed for molded-in applications featuring precise locating pins that ensure proper shut off to prevent plastic flow into the threads compromising integrity.
