Stop fighting messy, loose pins that ruin a build right when you’re almost done. This SN-58B crimping tool is made for clean, confident crimps on non-insulated, open-barrel terminals used in PC power leads, jumper wires, and connector housings. If you build PCs, repair cables, or tinker with electronics, you’ll feel the difference immediately: steadier holds, neater wraps, and fewer wasted terminals. Designed for consistent results across common connector styles and wire sizes.
