About this item

• 【Threaded Inserts Built to Last】 Crafted from premium brass, these heat set inserts deliver exceptional thermal conductivity, corrosion resistance, and rugged strength. The heat inserts resist cracking, stripping, and wear – ensuring secure fastenings that stay firm even after repeated assembly and disassembly
• 【Value Pack for 3D Printing】 This heat set insert kit packs the most commonly used 3D printer accessories – including 6 sizes (M2, M2.5, M3, M4, M5, M6) threaded inserts and an upgraded heat insert tool with 6 soldering tips (Iron Not Included). It ensures strong, reliable threads in all your 3D printed plastic parts, saving time and money on every project
• 【Precision Engineered Threaded Insert】 These brass hardware nuts feature precision threads that won't slip when installing. The 45° spiral knurl gives better torque and pull-out strength, biting into plastic for a stronger hold than straight inserts. No countersinking needed – just use a heat insert press to heat and press for a permanent fit
• 【Easy to Use】 Installing these nut inserts is simple with a standard soldering iron. Heat to the recommended temperature (180–230°C for PLA, 230–280°C for ABS), press the tip against the heatset insert for 3–8 seconds until it sits flush, then let cool for 30–60 seconds – you now have a strong, reusable metal thread embedded in your plastic part. This method also works with ultrasonic or heat press equipment
• 【Reliable Universal Thread Inserts】 These screw inserts are designed for all thermoplastics – PLA, PETG, ABS, PPS, PP, and more. Ideal for 3D prints, injection-molded parts, automotive casings, electronics, toys, and laptop housings. Every heat insert is rigorously inspected for durability, with responsive support you can count on
