Melco Box Spanner Whitworth

The 1/8" x 3/16" Whitworth box spanner is the smallest in the range, designed for extremely delicate fixings in precision instruments, fine mechanisms, and miniature assemblies. At 100mm (4 inches) long, this compact tool offers exceptional control whilst still providing the access advantages of a tubular design. These tiny Whitworth sizes are found in antique clock mechanisms, precision gauges, and small vintage engines where careful, controlled fastening is essential. The double-ended design ensures both sizes are immediately available during intricate work.
