Sealey 3/8" Drive Bi Hexagon Spark Plug Socket Metric

The Sealey 3/8" Drive Bi Hexagon Spark Plug Socket is a specialist 14mm socket designed for accessing spark plugs in confined engine bays where clearance is limited. Featuring WallDrive® technology and a thin wall construction, this socket delivers reliable performance in tight spaces where standard sockets cannot reach. The 12-point bi-hexagon design provides secure contact with spark plugs whilst minimising the risk of rounding, making it ideal for professional mechanics and automotive technicians working on modern engines with restricted access. A rubber insert retains the spark plug securely during removal and installation, preventing drops and simplifying the replacement process in awkward locations. With a standard depth of 64mm and 3/8" square drive, this socket integrates seamlessly with existing ratchets and extension bars. The thin wall construction maximises clearance around recessed spark plugs, making it particularly suitable for work on motorcycles, small engines, and vehicles with deep plug wells.
