RC 3mm Hex Driver Tip D=3.5MM L=75MM - K&S KS411  [KS411]

Precision 3mm hex tip for radio control models

This K&S KS411 3mm hex driver tip is an accessory for driving 3mm hex fasteners on scale model parts. The label shows D=3.5MM and L=75MM to indicate the tip diameter and overall length. It is useful for reaching recessed screws during assembly and for small adjustments when tuning servos, suspension, motor mounts, and gearbox fastenings on RC cars and trucks.

The tip is supplied as a single replacement head intended for compatible hex driver handles or bit holders commonly found in RC tool kits. When choosing a holder, confirm it accepts 75mm long bits and that the seating design secures the tip to prevent slipping while tightening or loosening small hex screws.

For best results, work methodically on small fasteners, avoid over-torquing, and recheck tightness after first runs; the extended length helps access hard to reach locations on servo mounts, shock towers, and motor brackets.
