Product description

  • Set Includes 130 brass threaded inserts (6 specifications M2 x 30, M3 x 30, M4 x 30, M5 x 20, M6 x 10, M8 x 10), designed specifically for plastic hot melt embedded threads, with 6 dedicated soldering iron tips and 2 soldering iron tip converters. By heating and melting plastic parts, rapid implantation of threaded inserts can be achieved, avoiding the risk of material cracking caused by traditional mechanical tapping.
  • 60W soldering iron ceramic heating element can quickly heat up, equipped with anti slip handle and temperature control knob, constant temperature adjustable, heat dissipation hole design optimizes heat dissipation efficiency, and improves operational safety. The high thermal conductivity copper material of the soldering iron head is heat-treated to prevent the nut from tilting and ensure precise hot melt positioning.
  • 130 threaded inserts forged from pure brass, with uniform thermal conductivity; Fully automatic deep thread processing, with no burrs on the surface, acid, alkali, and oxidation resistance, and a 50% increase in lifespan.
  • Quick head change Adapt to M2-M8 full specification mounting requirements through a converter. Place the nut in the pre drilled hole position, heat the soldering iron until the plastic melts, and remove the soldering iron when the melt is level with the surface of the part. After cooling, form an embedded thread to avoid excessive sinking and affecting bolt fastening.
  • Widely applicable scenarios compatible with thermoplastic materials such as PLA, PETG, ABS, PPS, PP, etc. Widely applicable to 3D printing models, injection molded parts, automotive plastic shells, laptop shells, PCB electronic assembly, etc., providing high reliability threaded connection solutions.
