A basin spanner is a specialized plumbing tool used to tighten or loosen large nuts and bolts, particularly in confined or hard-to-reach areas, such as underneath sinks and basins.
It is typically made of durable materials like chrome-plated steel or aluminum and features a long, adjustable handle with a jaw at one end. The jaw is designed to fit snugly around the nut or bolt, providing maximum grip and leverage.
