M5 Heat-Set Threaded Inserts for 3D Printing – Approx. 50-Pack

M5 Heat-Set Threaded Inserts

Add durable reusable M5 threads to 3D-printed parts, jigs, fixtures, enclosures, and maker projects.

These M5 heat-set threaded inserts are designed to be installed into compatible thermoplastic parts using a soldering iron or heat-insert installation tip. Once installed, they provide a stronger and more repeatable threaded connection than driving a screw directly into printed plastic.

Product Details

• Thread size: M5
• Approximate quantity: 50 inserts
• Packaged by weight, so exact piece count may vary slightly
• Designed for heat installation into compatible plastic parts
• Suitable for repeated assembly and disassembly

Common Uses

• 3D-printed enclosures and access panels
• CNC and maker-space jigs or fixtures
• Machine covers, brackets, and mounts
• Electronics housings and project boxes
• Parts that require removable screws or repeated servicing

Installation Guidance

• Model or drill the insert pocket to the correct diameter and depth for the insert.
• Heat the insert gradually with a soldering iron or dedicated heat-set tip.
• Press the insert straight into the part without excessive force.
• Stop when the insert is flush or positioned at the intended depth.
• Allow the plastic to cool completely before installing a screw.

Important Notes

Test fit and installation temperature on a scrap print before installing into a finished part. Excessive heat or pressure can deform the surrounding plastic. Installation settings vary by material, wall thickness, insert style, and printer calibration.
