Koswork M2/2.5/3/4mm Nut Cross Wrench (4, 5, 5.5 & 7mm) Tool - KOS13267

The Koswork KOS13267 Nut Cross Wrench is a multi-size RC tool designed for driving M2, M2.5, M3, and M4 hex nuts across 4mm, 5mm, 5.5mm, and 7mm sizes in a single compact tool. Built for RC car maintenance and setup, it covers the most common nut sizes found on 1/10 and 1/8 scale RC vehicles, making it a practical addition to any pit bag or workbench. The cross-handle design gives more torque and control than a standard nut driver, which matters when securing wheel nuts, bulkhead hardware, or suspension components.
