## Summary description

JustPi brass threaded inserts for 3D printing — pack of 500 pieces in various sizes. Designed to be embedded into printed parts to provide durable metal threads for screws and fastenings. Suitable for use with thermoplastics in prototyping and production, improving assembly strength and repeatable screw retention in housings, brackets and fixtures.

## Long description

JustPi threaded brass inserts for 3D printing, pack of 500 in various sizes, are designed to be embedded into thermoplastic parts to provide durable metal threads. These inserts create reliable screw joints in printed housings, brackets and fixtures, improving wear resistance and repeatable assembly performance in both prototypes and small-series production. The set contains a large quantity suitable for repeated use in workshop and production environments.
Advantages
Brass material offers good corrosion resistance and dimensional stability, while the knurled or heat-set design (depending on size) provides secure retention in common 3D printing thermoplastics. A pack of 500 reduces procurement frequency and ensures availability for multiple projects. Inserts deliver consistent thread quality and help prevent thread stripping in plastic parts, allowing for repeated assembly and disassembly without degrading the connection.
Suitable for
 Embedding into FDM/FFF printed housings and enclosures
 Creating strong attachment points in brackets and fixtures
 Prototyping and small-series production requiring repeatable screw connections
 Repairing or upgrading plastic parts that need metal threads
Key specifications
 Material: brass—offers mechanical durability and corrosion resistance
 Pack quantity: 500 pieces—suitable for workshop and production use
 Design: knurled/heat-set profile options for secure insertion into thermoplastics
 Compatibility: intended for use with common 3D printing thermoplastics such as PLA, ABS, PETG and similar materials
 Function: provides metal threads for standard machine screws to improve assembly strength and repeated fastening cycles
How to use
Install inserts by heating (for heat-set types) or pressing/press-fitting (for knurled types) into pre-printed holes sized to the insert specification. For heat-set installation, warm the insert with a soldering iron or dedicated insertion tool and push it into the hole until the flange is flush with the part surface; allow the surrounding plastic to solidify for a secure bond. For press-fit inserts, ensure the hole is dimensioned to provide interference and use a press or arbor to seat the insert straight and cleanly. After installation, verify thread alignment and torque screws according to the requirements of the assembled product.
Usage recommendations
 Use the correct hole diameter and insertion method for the specific insert size and plastic type; test on sample prints to confirm fit and mechanical performance before final production. For load-bearing applications, distribute multiple inserts or reinforce the surrounding geometry to avoid concentrated stress on a single threaded point.
