QUICK: Electrical nuts are great for connecting wires, no soldering required, just press the stripped conductor into the wire cover and tighten. Safe and Durable: The linear connector grips the wires firmly and forms a solid connection, and the spring inserted into the flame-retardant shell has good insulation and minimal aging. Saves time: Pre-twisted wires are not required, but we recommend twisting the wires first to make a more reliable, tighter connection. Applicable wires: 26 gauge - 10 gauge wire.<br><br>Colour:As Shown Material:abs<br><br>Package Contents: 1 set * wire connector nut kit (320pcs)(The color is random, no specification is accepted, and it does not affect the use)<br><br>Only the above package content, other products are not included.
