This five piece double ring ratchet spanner set from draper expert features hi torq® technology designed for professional tradespeople working in confined spaces. Manufactured from hardened and tempered chrome vanadium steel with a mirror chrome finish, these half moon spanners deliver exceptional corrosion resistance and durability for demanding workshop and site applications. The 100 tooth ratchet mechanism enables precision work with just 3.6° movement between clicks, making these spanners ideal for restricted access situations where traditional tools cannot achieve a full swing. The curved half moon design allows you to work around obstacles more easily, while the 12 point hi torq® ring ends grip the flats of fasteners rather than the corners, transmitting more torque whilst preventing damage to bolt heads and nuts. This comprehensive set covers the most commonly used metric sizes and comes supplied in a practical storage wallet for organised tool management. The hi torq® design spreads loading across the fastener flats, reducing the risk of rounding and extending the working life of both the spanners and fixings.
