The Sealey 3/4" Drive 38mm Hexagon Impact Socket is designed to tackle the most substantial fastening applications in heavy commercial vehicle repair, construction machinery maintenance, and industrial equipment servicing. The 38mm size is specified for the largest wheel nuts on heavy goods vehicles, buses, and construction equipment, as well as for major drive components and mechanical assemblies requiring maximum torque capacity. Manufactured using drop-forged chrome molybdenum steel, this impact socket delivers exceptional strength and resilience under the extreme forces generated by air impact wrenches. The innovative WallDrive® design engages fastener flats rather than corners, providing maximum grip whilst protecting both fastener and socket from damage.
