This 12-piece reversible ratchet combination spanner set from draper expert features hi-torq metric spanners manufactured from hardened and tempered chrome vanadium steel with black electroplating for corrosion protection. The set includes spanners from 8mm to 19mm, covering the most commonly used metric sizes for professional and serious diy applications. The 100-tooth ratchet mechanism enables precise 3.6 Movement, making these spanners ideal for working in confined spaces where traditional spanners require too much swing arc. The open end is set at 15 to provide better access to recessed fasteners, while the reversible ratchet feature allows you to change torque direction without removing the spanner from the fastener. The 12-point hi-torq ring end is designed to grip the flats of fasteners rather than the corners, distributing load more evenly and reducing the risk of rounding off nut and bolt heads. This design delivers superior grip and enables higher torque transmission, particularly valuable when working with seized or overtightened fasteners. The set is supplied in a storage and carry rack to keep your spanners organised and protected.
