About this itemPurpose: SN-58B crimper tool is designed to crimp 24-16AWG non-insulated open barrel, OEM-style terminals and wire splices.Capability: SN-58B wire crimping tool has a wide range of crimping capacity. It’s capable of crimping 2.5mm, 2.54mm, 2.8mm, 3.96mm, 4.8mm and 6.3mm pitch open barrel terminals from JST, Dupont, Molex, Amon, Amphenol, etc.Multiple Crimp Cavities: SN-58B is a combination of SN-28B and SN-48B crimping tools. It features 4 double crimp stations that simultaneously crimp the wire and insulation all in one action.Ratcheting Mechanism: To ensure a perfect crimp, the open barrel crimper will not disengage until a uniform crimp is completed or the quick release lever is triggered.Applications: Arduino, 3D printer, PCB, jumper wire and other electronic DIY projects.
