Product name: Hot melt nut indenter (Heat Insert Nut Iron Tip Kit) What this kit does Provides a set of heat insertion tips and matching brass threaded inserts for embedding metal threads into plastic parts. Designed to be used with a standard soldering iron or other heat source to melt plastic around the brass insert, producing a durable, loadbearing metal thread. Key benefits Creates strong, reusable metal threads in plastic parts to prevent stripped or worn plastic threads. Fast and repeatable installation compared with pressfit or glued inserts. Clean, lowprofile installation that preserves part aesthetics and function. Compatible with common , prototyping, and small production workflows, including 3D printed components. Main features Tip sizes: compatible with metric screw sizes M2, M3, M4, M5, M6, M8. Tip type: heat insert iron tips intended for use with a soldering iron or other suitable heating tool. Insert material: brass threaded inserts for secure, corrosionresistant threads. Function: heat insertion embedding the brass thread into plastic by melting a small volume around the insert for a secure mechanical bond. Compatibility and use Intended for embedding brass threaded inserts into plastic parts, including 3D printed components. Designed to work with a standard soldering iron or comparable heat insertion tool that accepts iron tips. Suitable for many thermoplastic parts and common 3D printing materials; follow material and temperature guidelines for your specific plastic. How it solves common problems Replaces weak plastic threads that strip easily with strong brass threads that hold screws repeatedly. Enables reliable fastening in prototypes, repairs, and assemblies without redesigning parts. Reduces assembly time and rework compared with tapping or adhesive methods. Typical applications Installing durable mounting points in 3D printed enclosures for electronics. Repairing stripped screw holes in plastic appliances, panels, or hobby parts. Adding reliable threaded inserts to small production runs or prototypes where machine tapping is impractical. Basic use steps Fit the correct tip for the insert size (M2–M8) to your soldering iron or heat tool. Heat the tip and use it to press the brass insert into the plastic until it seats. Remove heat and allow the insert and surrounding plastic to cool and solidify. Included information Product name: hot melt nut indenter. Sizes covered: M2, M3, M4, M5, M6, M8. Kit purpose: brass thread embedded kit for heat insertion into plastic using a soldering iron. Notes Use appropriate safety precautions when working with heated tools and melted plastic. Check compatibility of your soldering iron with the tips and follow manufacturer guidance for temperatures and tip attachment.
