Draper Single Open Ended Spanner Metric

The 41mm Draper Single Open Ended Spanner handles the heaviest industrial applications, including mining machinery, large marine equipment, and heavy plant maintenance. This professional-grade spanner is essential for major mechanical assemblies where substantial fasteners are standard. Forged from chrome vanadium steel and hardened for maximum durability, it maintains precision even under extreme working conditions. The raised jaw collar prevents spreading under high loads, whilst the black phosphate finish provides corrosion resistance in harsh industrial environments and eliminates health hazards in confined spaces.
