Description
Torque Wrench Adapter for Cylinder Base Nuts
This torque wrench adapter helps you reach cylinder base nuts in confined areas during engine assembly. Its narrow profile provides an alternative to a conventional socket when clearance around the cylinder limits access.
Two sizes in one tool
The adapter features 12 mm and 14 mm ring ends. A central square-drive opening connects the tool to a compatible torque wrench, allowing you to use the end that matches your cylinder base nut.
It is a useful addition to your toolbox for Yamaha Blaster engine work and other applications using these nut sizes.
