The W377B Performance Tool Combination Wrench is a heavy-duty, full-size hand wrench built for jobs where “snug” is not a suggestion—it’s a requirement. Made from drop-forged, hardened chrome alloy steel, it’s designed for strength and long service life, while the box end’s rounded corners help apply more torque with less risk of chewing up fasteners. Finished in a professional raised-panel, full-pattern design, it feels like a serious wrench because it is one.
