Print or drill a pilot hole in your plastic component. The hole diameter should be slightly smaller than the outer diameter of the brass insert you are using. — Prepare Pilot Hole 2. Attach the appropriate heat-set tip (M2-M5) to your soldering iron. Heat the iron to the recommended 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 soldering iron. Hold steady for 3-5 seconds while the plastic melts and cools, locking the insert firmly in place. — Press and Hold Insert ## Product details | Field | Value | |---|---| | Material | Lead-free Brass | | Temperature Resistance | Above 300°C (572°F) | | Knurling | 45-degree Spiral | | Plastic Compatibility | PLA, PETG, ABS, PPS, PP, TPU | | Installation Method | Heat-set with soldering iron (200-400°C depending on plastic) | | Pilot Hole Size | Slightly smaller than insert's outer diameter | | Hold Time | 3-5 seconds while cooling | | Cost per use | 306 inserts in kit — ₹4.25 per insert | | Shelf life after opening | Indefinite (metal components) | | Contraindications | Not suitable for metal-to-metal connections; requires heat-set installation. | | Allergens / common irritants | Lead-free brass is generally considered safe for most applications; avoid prolonged skin contact if sensitive. | | Brand | FFVRVSS | | Set Name | 300Pcs M2-M5 Kit+Tools | | Item Name | FFVRVSS 300+6Pcs Brass Threaded Inserts M2 M2.5 M3 M4 M5 for 3D Printing | | Material | Brass | | Metal Type | Brass | | Exterior Finish | Brushed | | Item Shape | Hexagonal | | Thread Size | M2, M2.5, M3, M4, M5 | | Thread Style | Spiral | | Thread Coverage | Fully Threaded | | Fastener Type | Insert | | Number of Items | 306 | | Number of Pieces | 306 | | Item Package Quantity | 1 | | Dimensions (L x W x H) | 10.9 cm x 6.2 cm x 1.7 cm (4.3 x 2.6 x 0.65 inches) | | Item Package Weight | 0.082 kg (0.18 lbs) | | 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?
