12-Point Long Pattern Wrench (COMBINATION WRENCH 5/16)

COMBINATION WRENCH 5/16|Armstrong’s wrenches are designed with modified radius corners on the open end for greater strength, and radius corners in the box end for greater torque. The radius corners also prevent rounding of fasteners and improves the turning of older, worn fasteners. The box end also features a 15° offset to clear obstructions, with a reinforced shank transition area for strength. The opening size is stamped at both ends for easy identification, and the body itself has a smooth, durable high-polish vibratory finish that eliminates the need to chamfer jaw tips.
