This HUDY 126345 Allen wrench is specified for 1/16 scale RC model work, with the stamped size .063 x 120mm (1/16) indicating the hex width and shaft reach. The design supports tasks requiring extra reach or fine control around small chassis parts.
Common applications include securing and removing hex fasteners on chassis plates, shock towers and steering linkages where a longer shaft improves access. The tool is presented as a model hobby accessory, defined by size and intended use rather than any road vehicle application.
To reduce the chance of rounding fastener recesses, make sure the key engages fully and use steady torque. The 120mm length offers better access for tight mounting locations frequently encountered during field setup and repairs.
Model builders working with 1/16 scale rigs will find the HUDY 126345 a simple, size-specific tool that eases chassis assembly and quick trackside tweaks.
