SOMELINE Mini-Fit Jr Connector Crimping Tool Kit, 18 Types 2-16 Pin 4.2mm Connectors with 24-16 AWG Pins, Ratcheting Crimper, Compatible with Molex, for PC Power, ATX, GPU PCIe, 3D Printer & DIY

SOMELINE 2542M hand crimping tool for Molex Mini-Fit Jr and Standard .062" crimp terminals. It can also be used for crimping Dupont 2.54mm and KF2510 connector terminals. When a crimping tool is used on a terminal, two crimps take place at the same time. One is the electrical connection between conductor and terminal. The other is the insulation crimp which provides strain relief against vibration and tension. Using a good quality crimping tool will ensure that a full, gas tight crimp is produced preventing future deterioration of the electrical connection and insulation breakage.Mini-Fit Jr. 4.2 mm plug and receptacle housings are made of UL94V-0 flame-retardant nylon with a secure latch. They are suitable for high-current, high-density wire-to-wire or wire-to-board applications such as consumer electronics, industrial equipment, and automotive electronics. Commonly used in PC power supplies for the 24-pin ATX motherboard connector, 4/8-pin CPU power connector, and 6/8-pin PCIe graphics card power cables, ensuring reliable high-current delivery.Kit Configuration:2–16 Circuits Connectors24–16 AWG Pins30–16 AWG CrimperDouble-layer Storage BoxUser Manual

• PRECISION RATCHET CRIMPING TECH: Features an auto-adjusting ratchet mechanism that ensures a consistent, OEM-grade B-type crimp every time. Unlike manual pliers, this tool applies the exact amount of force needed, creating a rock-solid union between conductor and insulation. Designed for 30-16 AWG wires, it eliminates loose connections and signal failures in critical circuits
• HIGH-CONDUCTIVITY TERMINAL KIT (24-16 AWG): Includes premium tin-plated brass terminals specifically sized for 24-16 AWG wires, offering superior oxidation resistance and current stability. The 4.2mm pitch housings (2-16 Pin) are crafted from industrial-grade Nylon 66 (UL94V-0), strictly flame-retardant and heat-resistant from -40°C to +105°C for maximum safety
• VERSATILE CROSS-COMPATIBILITY: A truly universal solution. The crimping pliers and connectors are fully compatible with Molex Mini-Fit Jr., Amphenol Minitek Pwr 4.2, and Standard .062" series terminals. Whether you are sourcing replacement parts or building from scratch, this kit ensures a perfect mate with existing industry-standard headers
• ENGINEERED FOR HIGH-CURRENT PC MODDING: Specifically optimized for 16 AWG wire builds to handle the high-wattage demands of modern GPUs and PSUs. This makes it the essential tool for creating custom ATX, PCI-E, and EPS power cables, as well as automotive electrical upgrades, ensuring stable power delivery with lower heat generation
• ERGONOMIC & BEGINNER-FRIENDLY: Designed for efficiency without fatigue. The non-slip TRP handle provides a comfortable grip for prolonged use. Features a built-in Quick Release Lever that allows you to open the jaws safely if a terminal is misplaced or stuck, making it easy for both DIY hobbyists and professionals to achieve perfect results
