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

3mm hex bit for fine tuning and repairs

This K&S KS411 3mm hex driver tip is intended for handling small hex fasteners on model components where a longer reach is needed. The markings D=3.5MM and L=75MM describe the working diameter and overall bit length, helping you choose the right tool for tight locations.

Sold as a single replacement head, the tip fits into compatible hex driver handles or bit holders found in many RC workshops. Verify your holder secures 75mm bits before use to ensure safe and steady operation while adjusting servos, mounts, and gearbox fittings.

When using this tip for tuning tasks, work methodically, avoid excessive torque, and double check fastener tightness after test runs to prevent loosening under load.
