Unlike basic fasteners, their heat-set design creates a strong, permanent thread within plastics like ABS and PETG. This ensures your projects, from custom enclosures to functional prototypes, maintain structural integrity through multiple assembly cycles. Imported from authorized US retailers, these nuts offer a premium solution for makers seeking enhanced durability and professional finishing for their 3D prints. — Superior Thread Reinforcement for 3D Prints - These brass nuts are perfect for Indian makers working with various 3D printing plastics (PLA, ABS, PETG) and hobbyists needing reliable threaded inserts. They are particularly useful for projects requiring frequent assembly or disassembly, such as custom 3D printer parts or electronic enclosures. While local alternatives might exist, PEUTIER nuts offer verified premium brass quality and high-temperature resistance, ensuring consistent performance in diverse Indian climates. Skip if you require nuts for non-standard thread sizes or applications exceeding 300°C. — Ideal for Indian Makers & Hobbyists ## How to use 1. Ensure your 3D printed part has pre-drilled tapered holes sized for M3 nuts. Clean any debris from the holes to ensure a good fit for the brass inserts. — Prepare the 3D Print 2. Using the included solder adapter and a compatible soldering iron (T18, 936, etc.), heat the brass nut. Gently press the heated nut into the tapered hole until it is flush with the surface. — Heat and Insert Nut 3. Let the brass nut cool completely within the plastic. As it cools, the brass expands slightly and the plastic conforms around the knurled pattern, creating a strong, permanent thread. — Allow to Cool 4. Once cooled, the threaded insert is ready for use. You can now screw M3 bolts into the reinforced threads for secure assembly of your 3D printed components. — Assemble Components ## Product details | Field | Value | |---|---| | Primary Material | Brass | | Temperature Resistance | Above 300°C / 572°F | | Installation Method | Heat-set insertion into plastics, injection molding | | Compatible Plastics | PC, PA, PLA, ABS, PETG, etc. | | Compatible Soldering Irons | T18, 936, 900M, ST soldering iron (compatible with FX888D, FX600, WLC100, SPG40, SP40NUS, 939D) | | Cost per unit | 120 nuts at {{ccc_offer_price}} — {{ccc_price_per_unit:120:nut}} | | Shelf life after opening | Indefinite (metal component) | | Contraindications | Applications exceeding 300°C, non-standard thread sizes, materials incompatible with heat-set inserts. | | Allergens / common irritants | None typically associated with brass in this application. | | Brand | PEUTIER | | Material | Premium Brass | | Color | Brass Color | | Thread Size | M3 x 0.5mm Pitch | | Nut Dimensions | M3x4x5mm (Outer Diameter: 3mm, Length: 4.7mm) | | Quantity | 120 pieces | | Included Accessories | 1 x M3 heat-set insertion tip, 1 x solder adapter | | Finish Type | Unfinished | | Item Weight | 0.05 kg | | Country of Origin | Not stated by manufacturer — US retail version, sourced from authorized US retailers | ## Frequently asked questions ### What thread size and standard does this nut use?
