Engine/Swing Arm Lock Nut Tool with 1/2-Inch Square Drive

Brief Overview

This is a specialized lock nut socket engineered for removal and installation of slotted swing arm and engine lock nuts on motorcycles. The tool features four internal engagement prongs that mate with the corresponding slots in the lock nut, preventing cam-out and rounding—a critical advantage over improvised solutions. It integrates a 1/2-inch square drive, making it compatible with any standard ratchet, extension bar, or torque wrench in your shop inventory. For mechanics working on Aprilia RS 125 models and similar applications, this tool eliminates the frustration of damaged lock nuts and delivers the precise engagement required for secure fastening. Complement this tool with other specialized fastening solutions like swing arm pivot lock nut tools and adjustable wheel bearing lock nut kits to build a comprehensive fastening toolkit.
