The wrong insert tip was included in the package, it was too large. Had to use one from an alternate kit. Review: Wrong Size of Soldering Iron Adapter Included - The insert tip (that screws onto the soldering iron adapter) that comes packaged with the 1/4"-20 Threaded Inserts does not fit inside the 1/4" inserts, so you can't actually heat the inserts using it. I thought it was just a one-off mispackaging error, so I requested a replacement, but the replacement came with the same oversized insert tip, leaving me without any way to get the threaded inserts heated and inserted in my project. I'm not bothering with hoping the third time's a charm, returning both and getting a refund. ## Features - Standard 1/4'' Size: 1/4''-20 size (8mm OD, 8mm Height) threaded inserts, compatible with 1/4''-20 screws. - Ideal Heat-Set Inserts for 3D Printing: Perfect brass threaded inserts for plastics. Easily embed into 3D printed parts or thermoplastics (PLA, ABS, PETG). - Premium Lead-Free Brass & Durability: Made from high-quality, lead-free brass for excellent heat conduction, corrosion resistance, and strength.
