Caterpillar 8H8573 speeder handles provide a 3/8-inch square drive for attaching sockets in service applications on heavy equipment. The rotating grip lets technicians spin fasteners rapidly before final tightening or loosening with a torque wrench or ratchet. Built as part of Caterpillar Service Tools, the handle matches standard 3/8-inch drive sockets and extensions for maintenance tasks on engines, transmissions, and undercarriage components.
