This 2" Black Oxide 12 Point 45 Degree Offset Striking Wrench is for use where a hammer or sledge is required to create extreme force / torque necessary to loosen or tighten large fasteners. Has a large striking surface for more efficient hammer contact, more force being applied to the fastener. The offset round handle design helps clear obstructions and the handle length permits use in confined areas. Box end opening is designed to remain engaged to the fastener when the wrench is struck. A heavy box end opening provides for greater transmission of torque and more strength while also providing access to confined fasteners. Manufactured from high alloy steel using the most up-to-date manufacturing process and heat treat for greater strength and durability. Meets or exceeds US Federal Specification GGG-W-636E.
