Pure Copper Material: Made of high-quality brass with good ductility, high thermal conductivity, and excellent electrical conductivity. Ensures stable circuit performance and reliable connections.Easy Connections: Terminals allow for quick and secure connections to hardwired equipment, enabling fast disconnects when needed.Quantity and Model: Includes 150 ring terminals in multiple sizes: 50 M3, 20 M4, 20 M5, 20 M6, 20 M8, and 20 M10. Packaged in a transparent storage box for easy organization and access.Open Barrel Design: Features an open barrel design suitable for solid or stranded wire connections. Operating temperature range: -30C to 60C (-22F to 140F).The bare wire connection port allows for easy crimping. Various terminal openings meet different wiring needs, ideal for small diameter wires and audio applications. Constructed from high-quality brass with smooth edges, high conductivity, and oxidation resistance. These ring terminals are thicker for improved durability and require no heavy-duty crimping tools. Open-barrel design supports both crimping and soldering. Includes 6 sizes: M3, M4, M5, M6, M8, and M10. Comes with a transparent storage box for convenient portability and organization.Package includes: 50 M3, 20 M4, 20 M5, 20 M6, 20 M8, 20 M10 ring terminals, 1 storage boxNote: Due to differences in lighting and screen settings, the actual product color may vary slightly from the images. A 12 cm measurement deviation may occur due to manual measurement.
