Brass Straight Knurled Embedment Nuts Insert Heat-Set

The Brass Heat Set Threaded Round Female Insert Nut is designed to create strong and reusable threaded mounting points in 3D printed plastic parts and compatible thermoplastics.

Unlike directly threading a screw into plastic, a brass threaded insert provides a durable internal thread that can withstand repeated assembly and disassembly. The external knurled surface allows the surrounding plastic to flow around the insert during heat-set installation and grip it securely after cooling.

The insert is made from brass, providing good heat resistance and corrosion resistance for suitable applications. Its internal female thread allows screws and bolts to be securely fastened into the plastic component.

These inserts are particularly useful for 3D printed enclosures, electronic housings, PCB mounting, brackets, prototypes, robotics, and custom mechanical assemblies.

Installation can be performed using a suitable soldering iron or heat-set insert installation tool. The insert is heated and carefully pressed into a correctly sized hole, allowing the thermoplastic to soften and flow around the external knurls.

Note: Product dimensions, thread size, finish, and appearance should be verified against the selected variant before installation. Product images and colour may vary slightly from the actual product.

Technical Specifications

Installation

Tools Required

• Brass Heat-Set Threaded Insert
• Compatible 3D Printed or Plastic Part
• Soldering Iron or Heat-Set Insert Tool
• Suitable Screw for the Internal Thread

Installation Steps

1. Prepare a correctly sized hole in the plastic or 3D printed part.
2. Place the brass insert onto a suitable soldering iron or heat-set insert tip.
3. Heat the insert carefully using a suitable temperature for the plastic material.
4. Position the heated insert squarely over the prepared hole.
5. Apply light and controlled pressure to allow the softened plastic to flow around the knurled exterior.
6. Keep the insert aligned and set it flush or to the required depth.
7. Remove the heating tool carefully.
8. Allow the plastic to cool and solidify before inserting the screw.
9. After cooling, the insert provides a reusable internal threaded mounting point.

Precautions

• Select the correct insert thread size and dimensions for your application.
• Use a hole diameter recommended for the specific insert and plastic material.
• Do not apply excessive heat, as it can damage or deform the surrounding plastic.
• Use a suitable soldering iron temperature according to the thermoplastic being used.
• Keep the insert properly aligned while installing.
• Do not apply excessive downward pressure during heat-set installation.
• Allow the plastic to cool completely before applying significant mechanical load.
• Use the correct screw size and thread type.
• Do not overtighten the screw after installation.
• Use appropriate ventilation when heating thermoplastic materials.
• Handle the heated insert and soldering iron carefully to avoid burns.
• Test installation on a sample piece before installing inserts into the final component.
