About this item
- ăProfessional Kit for Strong Plastic ThreadsăThis 286PCS set provides everything you need to create durable, permanent threads in plastic. The hot insertion method quickly melts and embeds the M4 brass nuts, offering a much stronger and more reliable connection than tapping directly into plastic, ideal for 3D prints and repairs.
- ăExtensive Versatility with M4 Nuts, Screws & CapsăOur kit includes 95pcs of M4 heat-set nuts, 95pcs matching screws, and 95pcs caps. This provides multiple installation options and is compatible with the most commonly used M4 size, ensuring you have the right fastener for various DIY and professional projects
- ăConvenient Tip-Swapping & Smart Temperature ControlăSwitch between hot insertion tips effortlessly without removing the soldering iron sleeve â simply unscrew one tip and attach another. The upgraded digital soldering iron (60W, 220-450°C) allows you to precisely monitor and adjust the temperature to suit different plastics, preventing melting or burning
- ăIncluded Stand, Tweezers & Connecting Rods for Ease of UseăWork safely and efficiently with the included soldering iron stand, which securely holds the iron when not in use. The fine-tip tweezers are invaluable for picking up small M4 nuts and hot tips, while the additional connecting rod makes switching between multiple tips quick and hassle-free
- ăDurable Brass Construction for Long-Lasting PerformanceăCrafted from premium brass, these threaded inserts offer excellent thermal conductivity for fast heating and superior corrosion resistance. The robust design ensures the knurled nuts lock firmly into plastic (PLA, PETG, ABS, etc.) and will not loosen over time, guaranteeing a professionalDurable Brass Construction for Long-Lasting Performance
