K&S KS411 3MM HEX DRIVER TIP D=3.5MM L=75MM  [KS411]

3mm hex driver tip for RC

This K&S KS411 3mm hex driver tip is an RC-scale accessory intended for driving 3mm hex fasteners on model components. The product designation includes its key dimensions as D=3.5MM and L=75MM which define the tip diameter and overall length respectively. Use it to reach recessed fasteners during assembly, perform routine maintenance, or make small adjustments while tuning servos, suspension, motor mounts, and gearbox fastenings on scale models.

The tip is presented as a single replacement head for compatible hex driver handles or bit holders used in RC workshops and field repair kits. When selecting a holder, verify it accepts 75mm long tips and the tip seating matches your driver system to ensure secure engagement during tightening or loosening of small hex screws.

For practical use, work methodically on small fasteners, avoid over-torquing, and check tightness after initial runs; the tip’s length helps access hard-to-reach locations common on servo mounts, shock towers, and motor brackets on RC cars and trucks.
