This 1/4" x 5/16" Whitworth box spanner addresses small to medium fixings commonly found in classic motorcycles, small machinery, and precision assemblies. The 100mm (4 inch) length strikes an ideal balance between compact handling and sufficient reach for recessed applications. The tubular design allows this spanner to work effectively in confined spaces where socket sets would be too bulky, whilst the double-ended configuration provides two frequently paired Whitworth sizes. This makes it particularly valuable for restoration work on vintage equipment.
