Insulated Ring Crimp Terminal Red, M5 Stud Size soldering tip These are Metal Film ResistorRing crimp terminals are used for connecting an electrical cable or wire to a stud or a post on an electrical component, such as a battery terminal. This ring terminal comprises highly conductive tin plated copper with conically tapered plastic insulation sleeves for optimal electrical conductivity and corrosion resistance. The terminal is protected by colour coded vinyl insulation, which aids in the rapid identification of the terminal size. This
