Key benefits Enables fast, reliable embedding of hot melt nuts into plastic parts, reducing misalignment and rework. Works with a range of common nut sizes, so you can use one toolset for multiple fastener types. Quickchange head design and good thermal transfer shorten task time and improve repeatability. Compatible with widely used soldering stations for easy integration into , prototyping, and light production workflows. Main features Size compatibility: supports M2 (fits common M2.5), M3, M4, M5, M6 (1/4'), and M8 hot melt nuts. Tool compatibility: fits standard 936 universal soldering iron tips; also suitable for common stations such as Hakko FX888D. Construction and contact: brass construction for good thermal conductivity; endface contact design prevents the nut from skewing and helps the insert seat squarely in the plastic. Interchangeable head system: female and subhead design with a handtightened knurled joint. Heads can be disassembled when cool to different threaded indenters quickly without tools. Practical use: designed for convenient, practical operation with standard soldering iron tips. Typical applications 3Dprinted parts: install heatset nuts into PLA, ABS, PETG, and other printed plastics to create durable threaded mounting points. Electronics enclosures and prototypes: embed inserts for repeated assembly and of housings, panels, and brackets. Smallbatch assembly and work: retrofit molded plastic parts or stripped threads in consumer products, fixtures, and tooling. Notes and usage tips Allow the head joint to cool before disassembling to change threaded indenters. Use with the listed soldering stations and standard 936 tips for fit and performance. The brass endface contact and knurled joint help ensure centered seating and repeatable results.
