Unlike basic screw-in methods, the heat-set process melts the plastic around the knurled brass insert, creating a robust, high-torque connection that won't strip easily. The stable insertion mechanism ensures a perfect 90° angle every time, vital for structural integrity and ease of assembly. This means your enclosures will be more secure, your components mount reliably, and your creations will withstand repeated use without wear on the plastic threads. **Ideal for Makers & Prototypers** — This kit is perfect for hobbyists, makers, and small-scale manufacturers in India looking to elevate their 3D printing projects. If you frequently assemble plastic parts, create enclosures for electronics, or build functional prototypes, this tool will significantly improve the durability and professional finish of your work. Those who need to frequently disassemble and reassemble projects will benefit most. However, if your projects only require occasional assembly or involve very thin plastic walls where heat might cause deformation, consider simpler screw-in nuts or adhesive solutions. ## How to use 1. Ensure your 3D printed part has pre-drilled holes designed for heat set inserts. The hole diameter should be slightly smaller than the insert's outer diameter for a snug fit. Clean any debris from the holes. — Prepare the Plastic Part 2. Select the appropriate insert tip for your chosen brass insert size. Attach it to the digital soldering iron and set the temperature between 180℃-500℃, adjusting based on the plastic type (e.g., lower for PLA, higher for ABS). Allow it to heat up. — Set Up the Soldering Iron 3. Align the brass insert with the pre-drilled hole, ensuring it's perfectly vertical. Gently press the heated soldering iron tip onto the insert. Apply steady, even pressure until the insert is seated flush with the plastic surface. Avoid excessive heat to prevent melting the plastic excessively. — Install the Insert 4. Allow the plastic to cool and solidify around the insert. Once cooled, carefully remove the soldering iron. Test the thread by screwing in the appropriate machine screw to ensure a secure and smooth fit. Repeat for all required inserts. — Cool and Test ## Product details | Field | Value | |---|---| | Soldering Iron Power | 60W | | Soldering Iron Temperature Range | 180℃ - 500℃ (356℉ - 932℉) | | Soldering Iron Voltage | 110V/220V (Auto-Voltage Conversion) | | Insert Material | Brass | | Insert Knurl Type | Knurled | | Total Inserts | 370 Pieces | | Insert Sizes Included | M2, M2.5, M3, M4, M5, M6 (1/4), M8 | | Installation Method | Heat pressing with soldering iron and specialized tip | | Insertion Angle | 90° Vertical | | Suitable Plastics | Thermoplastics (e.g., PLA, ABS, PETG) | | Cost per use | 370 inserts in kit — ₹22.98 per insert | | Shelf life after opening | Indefinite (store in dry conditions) | | Contraindications | Not suitable for thermosetting plastics; requires careful temperature control to avoid melting plastic excessively. | | Allergens / common irritants | Brass may contain trace amounts of lead; handle with care and wash hands after use. | | Brand | 3DZWMAN | | Model Number | ZW12Pro | | Set Name | Heat Set Insert Tool Kit (370 Piece) | | Material | Aluminum, Brass | | Exterior Finish | Aluminum | | Color | ZW12+ | | Item Weight | 1.31 kg (2.89 lb) | | Item Dimensions | 10.16 cm L x 19.7 cm W x 11.69 cm H (4 in L x 7.76 in W x 4.6 in H) | | Package Weight | 1.53 kg (3.37 lb) | | Package Dimensions | 20.4 cm L x 5.4 cm W x 30.6 cm H (8.03 in L x 2.13 in W x 12.05 in H) | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### What size heat set insert should I choose for my 3D printed part? Match the insert's thread size to the screw you plan to use (e.g., an M3 insert for an M3 bolt). Check the insert's outer diameter against the boss or hole designed into your print; the hole should be slightly smaller than the insert's larger knurled diameter for a secure melt-in fit. This kit includes M2, M2.5, M3, M4, M5, M6 (1/4), and M8 sizes, with specific dimensions listed in the product details. ### How are these heat set inserts installed? Heat set inserts are installed by pressing them into a thermoplastic part using a soldering iron fitted with a compatible tip. The iron briefly melts the surrounding plastic, allowing the insert to seat flush. As the plastic cools, it reflows around the knurls, locking the insert in place and providing durable metal threads. This kit includes various insert tips and a digital soldering iron. ### Can I use this tool with different types of 3D printing filament? Yes, this tool is designed for use with common thermoplastics like PLA, ABS, and PETG. The adjustable temperature control on the soldering iron (180℃-500℃) allows you to fine-tune the heat for optimal melting and bonding with different plastic types, ensuring a secure fit for the brass inserts. ### How many inserts are included in the kit? The kit includes a total of 370 brass threaded insert nuts. These are provided in assorted metric sizes: M2 (50pcs), M2.5 (100pcs), M3 (100pcs), M4 (50pcs), M5 (40pcs), M6 (10pcs), 1/4-20 (10pcs), and M8 (10pcs), offering a comprehensive selection for various projects. ### What is the advantage of using brass heat set inserts? Brass inserts offer excellent corrosion resistance and durability, ensuring long-lasting metal threads that are superior to plastic threads. Their knurled exterior provides a strong grip when melted into the plastic, preventing pull-out and stripping, which is crucial for components that require frequent assembly or disassembly. ### How do I ensure the inserts are installed straight? The 3DZWMAN tool features a stable, all-metal construction with a widened aluminum profile and V-shaped pulleys designed to guide the insertion process. This setup helps maintain a 90° vertical insertion angle, ensuring the inserts are seated correctly and securely without tilting. ### How to choose the right heat set insert for my project? Consider the screw size you intend to use for thread compatibility (e.g., M3 screw needs an M3 insert). Also, check the insert's outer diameter against the hole size in your 3D print; the hole should be slightly smaller than the insert's diameter for a tight fit. The kit includes a range of sizes from M2 to M8 to accommodate most common applications. ## Compliance No product-specific compliance warnings identified.
