The NSD081 set provides four metric hex drivers for maintenance and assembly of RC-scale models. Included sizes are 1.5mm, 2.0mm, 2.5mm and 3.0mm, covering typical hex screw dimensions found on servos, motor mounts, gearboxes and suspension parts. Titanium tips are specified to increase wear resistance across repeated fastening cycles.
These drivers function as hand tools at the bench or track; matching each tip to the correct screw size reduces fastener damage and helps maintain consistent torque control when installing or adjusting components such as servo mounts and chassis hardware.
The NSD081 is intended as a compact, reliable metric hex option for routine assembly and maintenance; keep tip sizes matched to screws to protect hardware and retain repeatable tightening performance.
