The 50Mm Slogging Spanner (Open End, Crv) Is A Heavy-Duty Tool Designed For Use In Applications That Require High Torque, Typically Where Standard Wrenches May Not Suffice. Made From Chromium-Vanadium (Crv) Steel, It Offers Superior Strength And Durability, Making It Ideal For Tough Industrial Tasks. The Open-End Design Allows Easy Access To Large Fasteners, And Its Large 50Mm Size Makes It Perfect For Working With Bigger Bolts Or Nuts. The Slogging Feature Means The Spanner Can Be Struck With A Hammer (Slogging) To Provide Additional Force For Loosening Or Tightening Without Damaging The Tool.
