About this product
This double-ended Whitworth box spanner covers 1/4" and 5/16" sizes, suited to small to medium fixings found on classic motorcycles, small machinery and precision assemblies. At 100mm (4 inches) long, it is slimmer and longer than a socket, allowing it to reach nuts and bolts in narrow recesses where sockets are too bulky, making it useful for plumbing maintenance, automotive repair and restoration work.
It is made from bright plated steel and is compatible with a tommy bar for extra leverage. The double-ended design provides two commonly paired Whitworth sizes in one tool, improving workflow when both are needed.
