Backed by strict quality inspection and responsive customer support ## Why choose this product **Engineered for Durability and Precision** — The FFVRVSS Brass Threaded Inserts are crafted from premium lead-free brass, ensuring excellent thermal conductivity and corrosion resistance. This material choice guarantees longevity and strength, withstanding temperatures above 300°C. The precise threads and 45-degree spiral knurling are specifically designed to resist stripping and pull-out, providing a significantly stronger and more reliable connection than standard straight-thread inserts. This focus on material science and design ensures your 3D printed projects maintain structural integrity over time. **Ideal for Makers, Skip if Using Metal-to-Metal** — This kit is perfect for 3D printing enthusiasts, hobbyists, and DIYers needing to add durable threads to plastic components like electronics enclosures, circuit boards, and toy assemblies. It works seamlessly with PLA, PETG, ABS, and other thermoplastics. However, these inserts are designed exclusively for embedding into plastic. If you require threaded connections between metal parts or for high-pressure hydraulic systems not involving plastic, these brass inserts would not be suitable. ## How to use 1. Print or drill a pilot hole in your plastic part. The hole diameter should be slightly smaller than the outer diameter of the brass insert for a snug fit. — Prepare Pilot Hole 2. Attach the matching heat-set tip to your soldering iron. Heat the iron to the appropriate temperature: 200-250°C for PLA, or 350-400°C for PETG/ABS. — Heat Soldering Iron 3. Align the brass insert with the pilot hole and press it straight in using the heated tip. Hold steady for 3-5 seconds while the plastic melts and cools, locking the insert firmly in place. — Insert and Secure ## Product details | Field | Value | |---|---| | Primary Material | Lead-Free Brass | | Heat Resistance | Above 300°C (572°F) | | Knurling Style | 45-degree opposing spiral | | Installation Method | Heat-set with soldering iron (200-400°C depending on plastic) | | Compatible Thermoplastics | PLA, PETG, ABS, PPS, PP, TPU | | Applications | 3D prints, electronics enclosures, circuit boards, toys, furniture, automotive, laptops | | Cost per use | 467 pieces total — ₹3.74 per piece | | Shelf life after opening | Indefinite (metal components) | | Brand | FFVRVSS | | Set Name | 460Pcs M2-M6 Kit+Tools | | Material | Brass | | Finish Type | Brass | | Color | Brass Color | | Thread Sizes | M2, M2.5, M3, M4, M5, M6 | | Total Pieces | 467 (460 inserts + 7 tools) | | Item Weight | 150 g (0.15 kg) | | Package Dimensions | 13.4 cm x 9.6 cm x 1.7 cm (5.5 in x 4 in x 0.65 in) | | 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 fitting nut use?
