Brass Inserts M2.5 x 5mm – Heat Set Threaded Insert Nuts

The Brass Inserts M2.5 x 5mm are high-quality heat-set threaded nuts designed for use with thermoplastics such as PLA, ABS, or PETG. These precision-engineered inserts provide a durable and reusable metal thread in 3D printed or injection-molded plastic parts. Their knurled design ensures strong grip and resistance to pull-out, making them ideal for structural components, enclosures, and mechanical assemblies.

Simply heat the insert and press it into a pre-drilled hole in your plastic part using a soldering iron. Once cooled, the insert bonds securely with the plastic, providing strong internal threads for machine screws.
