The Arrowmax AM-121130 Ball Driver Hex Wrench Tip is a practical spare for hobbyists who need precise tools. Made from spring steel, the 3.0 x 120mm tip resists deformation and maintains consistent torque behavior for routine maintenance.
Spring steel is selected for its ability to bounce back after repeated torqueing, so the hex profile remains sharp and dependable. That stability reduces the chance of slippage when you are tightening small fasteners.
The 3.0mm size suits a wide range of small RC screws and linkages, giving you flexibility during setup and repair. Precision machining helps prevent rounded heads and keeps adjustments smooth.
