DESCRIPTION A Ring Spanner Set comprises multiple double-ended ring (box-end) spanners designed to fit hexagonal nuts and bolts of various sizes. Each spanner has closed, circular heads at both ends, typically with different sizes on each side, offering a secure and precise grip on fasteners to minimize slippage and rounding. Made from high-grade chrome vanadium steel, these spanners are drop-forged, heat-treated for strength and durability, and often finished with corrosion-resistant nickel chrome plating or polished finishes. They are widely used in automotive repairs, mechanical and industrial maintenance, plumbing, and assembly work where tight, secure fastening is required in confined spaces.
