TRF421X 3x6mm Hex Flat Screw, model spare part

The TRF421X 3x6mm Hex Flat Screw is a dedicated spare part for model maintenance, repair and exact replacement work. Its stated 3x6 mm specification gives a clear reference for matching an existing fastener in a compatible assembly, which helps keep servicing focused and avoids the guesswork of mixed hardware. The hex drive format is designed for use with a matching hex tool, allowing controlled tightening during bench work. A flat head profile sits flush at the intended fixing point, which supports a tidy fit where this screw type is required. The pack contains 5 screws, useful for replacing missing hardware, refreshing worn fixings or keeping a few matching parts ready in a workshop drawer. As a model accessory rather than a general household fastener, it belongs in planned upkeep of compatible hobby builds. This spare part fits naturally into regular maintenance sessions, whether a model is being checked after running, rebuilt section by section or restored with matching hardware kept close at hand. The compact pack size also works well for parts storage alongside other workshop essentials used for ongoing model care.
