Armattan Prop Ratchet Tool

This handy prop ratchet tool allows you to tighten or loosen nylock prop nuts with minimal effort and without having to reset the grip on the tool.
At the core of this, you’ll find a one-way roller bearing and two regular bearings around that for optimal stability, even after hundreds of prop swap cycles.

The prop nut sockets are designed to fit the standardized 8mm hex fitting found on M5 nylock nuts.
The side arms give you great leverage to rotate even the most stubborn locknuts.
These sidearms also act as a 5.5mm ring tool to fit smaller nuts such as those found on your flight controller stack.
