This 120mm variant represents the longest option in the Sealey 1" Drive Hexagon Impact Socket range, providing maximum reach for the most challenging fastener access scenarios. The 120mm length is essential for professional technicians working with large commercial vehicles, agricultural machinery, or industrial plant equipment where extreme depth is required to engage deeply recessed fixings effectively. Manufactured from premium chrome molybdenum steel through precision drop-forging processes, this impact socket offers uncompromising strength for heavy-duty workshop applications. The advanced WallDrive® design ensures optimal force distribution across fastener flats, dramatically reducing the risk of rounding whilst delivering superior torque transfer efficiency. The phosphate finish provides robust corrosion resistance, maintaining performance standards even in harsh working environments. Specifically engineered for air impact wrench use, this socket has been hardened and tempered to withstand the extreme forces generated during high-torque operations. The 120mm extended reach makes this socket invaluable for HGV technicians, agricultural engineers, and industrial maintenance professionals who regularly encounter deeply positioned fasteners that standard sockets cannot reach.
