Molex Hand Crimping Tool for Nano-Fit Crimp Terminals

Importance of a High-Quality Crimp

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. It is important that the electrical connection is gas tight without any voids between the wire strands and the terminal. If there any voids present, then corrosion can occur causing resistance and excessive heat which damages the electrical connection. 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

Hand Crimping Tool - Overview

From Molex a manual crimping tool made from high-quality materials with precisely designed crimp profiles that enable terminals to be crimped to a high specification. This crimping tool consists of two handles, ratchet mechanism, die assembly and terminal locator. The excellent force ratio of this hand crimping tool along with the ergonomically designed soft grip handles makes it easy to handle and comfortable to use

Ratchet Mechanism

The ratcheti is pre-set to a specific force and remains locked until the handles of the tool are fully closed and the dies are bottomed. The handles cannot be opened until a full crimping cycle is achieved therefore preventing partial crimps. Once the cycle is complete the handles will spring open. The ratchet also enables the operator to repeatedly produce consistent, high-quality crimps. If jamming or terminal misplacement occurs the handles can be easily opened using an emergency ratchet release lever


This hand crimping tool features a user-friendly terminal locator and wire stop which accurately position the terminal and hold it securely in place during the crimping process. The locator simply swings away from the crimp tool allowing the terminal to loaded into the correctly sized nest in the locator. The locator is then swung back into place with the terminal positioned correctly for crimping. The pre-stripped wire is inserted through the terminal against the wire-stop and crimping can proceed

Removable Crimp Head

The crimping head of this crimp tool can be removed from the tool and used in a range of Molex powered tools as follows;
Air powered tool - (Molex part number 63816-0100) with air powered crimp adapter (Molex part number 63816-0700)
Battery powered tools - (Molex part numbers 63816-0200 and 63816-0250) with battery powered crimp adapter (Molex part number 63816-0600)
