The Flank Drive Deep Socket is used for removing and installing spark plugs in internal combustion engines. Its deep socket design allows it to reach spark plugs seated deep within engine compartments, providing a snug fit around the hexagonal shape of the plug. The socket’s flank drive design ensures that torque is applied to the flats of the hexagonal surface rather than the corners, which prevents rounding off the edges and ensures a secure grip.Attributes:• Provides a secure fit to prevent stripping of spark plugs.• Chrome finish for increased durability and resistance to corrosion.• Features a deep well to accommodate long spark plugs.• Provides accurate control less effort is required during spark plug removal.• Provides a 3/4 inch square drive for secure grip on spark plugs for removal.Applications: The Flank Drive Deep Socket is used to ensure the efficient and secure removal and installation of spark plugs in equipment engines during maintenance operations.
