The Sealey 3/4" Drive 38mm Deep Hexagon Impact Socket is designed for the largest standard metric fastener applications encountered in heavy commercial vehicle maintenance, construction equipment, and industrial machinery servicing. The 38mm size is frequently specified for large truck wheel nuts, heavy-duty driveline components, and plant equipment where maximum torque capacity and deep reach are both critical. Constructed from drop-forged Chrome Molybdenum steel, this impact socket delivers the exceptional strength and resilience required for high-torque operations with air impact wrenches in demanding professional environments. The socket has been hardened and tempered to maintain structural integrity under repeated high-impact loading whilst preserving precise dimensional tolerances over prolonged use. Incorporating Sealey's innovative WallDrive® technology, this socket revolutionises fastener engagement by gripping across the flat sides rather than the corners—a design innovation that distributes force more evenly and significantly reduces the risk of rounding off bolt heads. This advantage proves particularly valuable when tackling corroded or seized fasteners in challenging maintenance situations. The deep profile provides extended reach for recessed applications and long threaded work, whilst the phosphate finish ensures reliable corrosion resistance in harsh workshop conditions. Backed by a lifetime guarantee, this socket represents the pinnacle of professional-grade engineering.
