The sealey 3 8 drive bi hexagon spark plug socket with universal joint is a specialist socket designed for accessing and removing spark plugs in confined engine spaces. This 14mm metric socket combines a thin wall design with an integrated universal joint, making it ideal for tight clearances where standard sockets cannot reach. Manufactured from hardened and heat-treated chrome vanadium steel, this socket delivers the strength and durability required for professional automotive and small engine work. The 12-point bi-hexagon design provides a secure grip on spark plugs, whilst the internal magnet holds the plug firmly in place during installation or removal, preventing drops in awkward spaces. The universal joint features a rotating 360 head that allows the socket to work at various angles, providing exceptional accessibility when working around obstructions in engine bays. The knurled exterior ensures a reliable grip even with oily hands, whilst the standard depth design accommodates most metric spark plug applications. With a 3 8 square drive fitting and 100mm overall length, this socket integrates seamlessly with standard ratchets and extensions.
