Sealey 3/8" Drive Spark Plug Socket with Universal Joint and Extension 3/8" 16mm

About this tool

The Sealey AK6576 is a 3/8" drive spark plug socket with universal joint and extension bar, designed for spark plug removal and installation in restricted engine bays. Constructed from hardened and heat-treated Chrome Vanadium steel, this socket delivers the strength and durability demanded by professional mechanics and automotive technicians. The thin wall design allows access in tightly packed engine compartments where standard sockets simply won't fit. The integrated internal magnet securely retains the spark plug during both installation and removal, reducing the risk of dropping plugs into inaccessible areas. The universal joint features a 360° rotating head, giving the flexibility to work at awkward angles without compromising torque transfer. At 310mm in overall length, the extended reach makes it well suited to modern engines with deep-set plug housings. The knurled exterior provides a secure manual grip when positioning the socket by hand, while the 12-point design ensures reliable engagement with the plug hex.
