RC Car Tools

Match RC hex and nut driver sizes

Read the fastener itself or the model parts list before buying. The tool for a recessed screw and the socket for a wheel nut use different working surfaces.

Identify the working faces

For an internal hex, read the recess across its flat faces. For a socket, measure the outside faces of the nut. Avoid converting a nearby metric or imperial size by eye.

Plan around restricted access

Compare the shaft length before choosing a driver for a recessed screw. For a wheel socket, check the outside diameter and depth against the recess and any protruding axle.

Build a set around your car

Write down the sizes the model needs before comparing sets. A set with small driver tips can be more useful for some cars than one centered on wheel nuts and larger shafts.

Guide questions

Do the two tools marked 5.5 mm do the same job?

Check whether the mark describes the tip of a driver or the opening of a nut socket.

What if a tip feels loose?

Confirm the profile and measurement before applying torque. A close size is a poor substitute for an exact fit.

Can I use the same set on every scale?

Compare your model's fastener specifications. Scale is a starting point rather than a list of tools.

Which accessory suits the job?

The original Tekno TKR1116 excludes deep half-offset truck wheels. Compare the 17 mm long-shank TKR1116B when reach is the issue, and check the actual clearance in both cases.

Use the MIP 9602 straight drivers for a direct approach. Compare the 9606 ball-end set if a part prevents straight alignment with the recess. The size ranges are different.
