TRF421/X 5x7x5mm Hex Ball Nut, model spare part

The TRF421/X 5x7x5mm Hex Ball Nut set supplies 5 matching spare parts for detailed model maintenance where exact hardware size matters. Each nut measures 5 x 7 x 5 mm, giving a clear specification for replacing worn fastening points in compatible assemblies and keeping mechanical connections consistent during service work. The hex form allows tool-based fitting and removal, which is useful when access is tight and adjustments need to stay controlled around small moving parts. As a dedicated spare part set, these nuts suit routine workshop tasks such as replacing lost hardware, refreshing used link points, or keeping matching replacements on hand for future repairs. The pack count of 5 supports repeated maintenance without mixing unmatched pieces from different sources. On the bench, this set fits neatly into organised model servicing, whether a current build needs a direct replacement or an existing chassis is being checked over after running sessions. The compact dimensions make it easier to match the required hardware before installation and help keep compatible mechanisms assembled with the intended fit.
