3.8mm Single-Head Spade Terminal Cable Red Black Yellow

3.8mm Single-Head Spade Terminal Cable — Red / Black / Yellow | 10–100cm | Automotive & DIY Wiring

Pre-crimped 3.8mm single-head spade terminal cables — the fastest way to add a reliable spade connector to a wire without a crimping tool. Each cable is factory-crimped with a 3.8mm female spade terminal on one end and a bare wire on the other, ready for soldering, splicing, or connecting to a second terminal. The 3.8mm spade size is the standard for automotive relays, fuse boxes, switches, and appliance terminals. Available in red, black, and yellow for colour-coded wiring, and in lengths from 10cm to 100cm for different routing requirements.
