The GEARWRENCH laminated box wrenches are available in the most common SAE and metric sizes in both flat and offset styles. The open head and body design are easy-to-clean to ensure dirt and debris does not get trapped blocking the ratcheting mechanism. The openings are broached for an accurate, non-slip on fasteners. The wrenches are heat treated for durability and are chrome plated for corrosion resistance. Wrenches are reversible by turning the wrench over.
