Non-insulated butt terminals are a type of electrical connector used to join two or more wires together. These terminals are made of high-quality materials, such as copper or brass, and are designed to provide a secure and reliable connection. Non-insulated butt terminals are ideal for applications where there is no risk of electrical shock or short-circuiting, as they do not have any protective covering. These terminals are commonly used in automotive, marine, and industrial applications, as well as for DIY projects. They come in a range of sizes and are easy to install with a crimping tool.
