Arrowmax am-429125 Limited Edition Ball Driver Hex Wrench 2.5 x 110mm  [am-429125]

Ball Driver Tool: 2.5 x 110mm Explained

This limited edition Arrowmax ball driver am-429125 is an RC-focused hex tool intended to access recessed or angled hex screws while preserving solid contact on 2.5mm hex heads. The ball tip design accepts slight off-axis entry without cam-out, which is helpful when bodywork or chassis layout restricts a straight approach.

Practically, the driver is used to set shock caps, adjust linkage ball ends and work on tight-clearance hex screws where alignment is difficult with a straight driver. The 110mm effective shaft provides reach into deeper assemblies and the 2.5mm tip matches common fasteners on 1/10 and comparable class models.

Work method: fit the ball tip into the hex recess, keep steady axial pressure and let the minimal angular play align the driver to the screw head before turning with measured torque. Use short, precise turns at the end to protect small threads in plastic hubs or lightweight suspension parts from stripping.

Care: remove debris from the tip and inspect it before precision setup sessions; replace the driver if the tip rounds to maintain reliable engagement with small hex heads during tuning and repairs.
