Where the Tamiya 51131 6x7mm Ball Nut Fits

The Tamiya 51131 - 6x7mm Ball Nut is sold in a pack of four and is intended for small-scale connection points in RC models. These units give neat, low-profile fixing for steering servos, link rods and other small assemblies where space is tight.

Keeping Model Joints Secure

By offering rigid seating for linkages, these ball nuts help reduce play in moving parts, which improves predictability during handling and reduces the need for constant trimming. They are a sensible choice when tidying up a build.

Fits a Range of Models

The 6x7mm dimensions are widely used across many car kits and replacement parts, allowing these nuts to be swapped between projects. Their standard sizing makes them a practical spare for workshops and parts boxes.
