The GEARWRENCH Slugging/Striking Wrenches are designed for applications where the force or torque needed to loosen or tighten fasteners is so great that a hammer or sledge is required. These wrenches are offered in three styles: 6-point Slugging, 12-point Slugging, and 12-point 45-degree Offset Striking. The 6-Point Slugging wrenches are available in 14 sizes from 1-1/16" to 3-7/8". The 12-Point Slugging Wrenches are available in 33 sizes from 1-1/4" to 4-5/8" and the 12-Point 45-degree Offset Striking Wrenches are available in 28 sizes from 1-1/16" to 3-1/8". Each wrench is made of alloy steel, features a hard stamped size marking on the handle, and meets or exceeds GGG-W-636e and ASME B107.410 specification.
