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

Ball Driver Hex Wrench 2.5 x 110mm

This limited edition Arrowmax ball driver am-429125 is an RC-scale hex tool designed to reach recessed or angled hex screws while keeping a secure engagement on 2.5mm hex heads. The ball driver profile lets the tip enter screws at slight angles without cam‑out, which is useful when access is limited by chassis or bodywork.

In practical tuning and maintenance the tool is used to set shock caps, linkage ball ends and tight clearance hex screws where a straight driver would be difficult to keep aligned. The 110mm effective length gives reach into deeper assemblies while the 2.5mm tip size matches common hex fasteners found on 1/10 and comparable class models.

Work method: seat the ball tip into the hex recess, apply steady axial pressure and allow the slight angular play to align the driver to the screw head, then turn with controlled torque. Use short, controlled turns for final torque to avoid stripping small threads in plastic hubs or lightweight suspension parts.

Care: keep the tip clean of debris and inspect for wear before precision setup sessions; replace if rounded to preserve engagement with small hex heads during tuning and race-day repairs.
