About This

• COMPLETE 380-PIECE HEAT-SET INSERT ASSORTMENT – This kit includes 8 popular metric and imperial sizes: M2, M2.5, M3, M4, M5, M6, 1/4 and M8, with quantities ranging from 10 to 100 pieces per size. One set provides ample supply for multiple 3D printing, DIY, and plastic part repair projects without frequent reordering.
• KNURLED DESIGN FOR SECURE HOLDING – The external knurling pattern provides excellent grip when melted into plastic materials. Once installed, these inserts lock firmly into place, resisting rotation and pull-out forces to create strong, reusable threads that outlast tapping directly into plastic.
• PREMIUM BRASS CONSTRUCTION – Made from high-quality solid brass, these inserts offer excellent thermal conductivity for fast, even heating during installation. The corrosion-resistant material ensures long-lasting performance, even in environments with temperature changes or mild moisture exposure.
• PRECISE METRIC DIMENSIONS FOR RELIABLE FITTING – Each insert is manufactured to exact specifications with consistent outer diameter, length, and thread clarity. This ensures a snug press-fit into printed holes and smooth engagement with standard screws, eliminating wobble or misalignment in your final assembly.
• VERSATILE APPLICATION FOR 3D PRINTING & PLASTIC REPAIR – Ideal for adding durable metal threads to 3D-printed prototypes, functional parts, enclosures, and repaired plastic housings. Use with a standard soldering iron and compatible insertion tip to create professional-grade threaded joints that can be assembled and disassembled repeatedly.
