Mcgard lock 1/2x20 mercury [0344415]

Code: 0344415

Extremely resistant, simple to use and safe anti-theft protection system for outboard unit, stern drive or propeller. Simply replace one of the mounting nuts with a McGard locking nut/collar. The free-spinning collar turns freely on itself and makes disassembly impossible. Only with the McGard key included in the package it will be possible to unscrew the anti-theft device.
