Eight piece ring spanner set is a simple, double-headed spanner set with a profile set in a looped head. A spanner works by gripping a nut and bolt and twisting it clockwise or anticlockwise to tighten or loosen it.
Tata Agrico spanners are made from chrome vanadium steel. Chromium and vanadium are metal elements that are added to steel to increase the metal's strength. Chromium also increases the steel's resistance to rusting.
Tata Agrico spanners are plated with either nickel or chromium or both. Nickel and chromium are more corrosion-resistant than steel and the layer protects the iron from reacting with oxygen to produce rust. They are also used as they give the tool an attractive finish
