This Wright Tool 1-1/2" drive standard castellated socket handles 3-1/2" fasteners with precision. Built for castellated nuts and bolts with slots or holes, this heavy-duty socket weighs nearly 12 pounds and measures 5.38" in length. The forged and machined construction delivers the strength you need for large industrial fasteners.
The socket features an oiled black oxide finish that resists corrosion while providing easy grip identification. Precision heat treatment and tempering optimize hardness and ductility for long-term durability. Easy-to-read size stamps help you grab the right socket quickly. Made in Barberton, Ohio and meets ASME B107 hand tool standards.
Heavy equipment mechanics, shipyard workers, and industrial maintenance crews rely on this socket for castellated fasteners on large machinery, marine applications, and structural work. The 1-1/2" drive handles high torque applications where smaller drives would fail.
