Combination spanner set

A  combination spanner set typically refers to a collection of twelve different-sized spanners that feature both open-end and box-end configurations. Combination spanners are versatile tools commonly used in mechanical and household applications. The open end is designed to grip fasteners in tight spaces, while the box end provides a more secure grip on the flats of a nut or bolt. The set usually includes a range of sizes to accommodate various fastener dimensions. Each spanner in the set may be marked with its specific size, typically in metric or imperial units. This versatile tool set is essential for tasks that require tightening or loosening nuts and bolts in different applications, providing flexibility and convenience for the user.
