Round Threaded Brass Heat-Insert Nut (10 pcs)

Round Threaded Brass Heat-Insert Nut

Durable Threading for 3D Printed Parts

The Round Threaded Brass Heat-Insert Nut is an essential component for adding strong, reusable threads to your 3D printed parts. Designed specifically for thermoplastics like PLA, PETG, ABS, and nylon, these inserts provide a secure and wear-resistant connection that holds up through repeated use and assembly.

Made from high-quality brass, these inserts are corrosion-resistant, highly conductive, and built to withstand the heat and stress of installation. The round knurled outer surface ensures a strong mechanical bond with the plastic, preventing the insert from rotating or pulling out once embedded. Simply heat the insert using a soldering iron and press it into a pre-sized hole in your printed part. Once cooled, the plastic solidifies around the insert, creating a tight and permanent fit.

These heat-insert nuts are perfect for applications that require fastening with machine screws, such as enclosures, mounts, or mechanical assemblies. They provide a much stronger and more reliable alternative to tapping threads directly into plastic, which can wear out or strip under pressure.

Available in multiple sizes to suit different screw diameters, these inserts are widely used by makers, engineers, and manufacturers to improve the functionality and durability of 3D printed parts.
