DESCRIPTION A Ring Spanner (also known as a box-end spanner) is a hand tool used to tighten or loosen nuts and bolts. It features a closed, circular-shaped head (ring) that grips the fastener securely on all sides, typically with 6-point or 12-point internal geometry. This design minimizes slippage and reduces the risk of rounding the fastener edges. Ring spanners are widely used in automotive, mechanical, plumbing, and industrial applications where precision and secure grip are critical, especially in tight or recessed spaces. They are usually made from high-grade chrome vanadium steel and heat treated for durability and resistance to wear. The handles are often ergonomically designed with a sand-blasted finish for comfortable grip.
