Spark Plug Socket 16mm 3/8in Drive Extra Long 310mm Magnetic Swivel

A 16mm spark plug socket built for reaching plugs set deep in awkward engine bays. With a 310mm extra long body, 3/8in square drive, 12-point end, internal magnet and universal joint, it gives better access where a standard socket can struggle.

Used for spark plug removal and fitting on a range of cars and motorcycles, this socket is handy for servicing, vehicle maintenance and regular garage work. The long reach helps when plugs sit below covers or deep within the cylinder head area, while the joint makes it easier to work around pipework and other tight obstructions. For home mechanics and trade users alike, it is a practical option when carrying out tune-ups, misfire diagnosis or routine plug changes.

The 16mm size suits spark plugs that require that socket size, and the chrome vanadium steel construction gives it the strength needed for repeated workshop use. Its internal magnet helps hold the spark plug during removal and refitting, which can be especially useful when working in narrow spaces where dropping the plug would slow the job down. The 12-point end supports engagement on the plug fitting, and the 3/8in drive makes it easy to use with common ratchets and extensions already in a tool kit. The extra 310mm length and built-in universal joint help reduce the need to keep swapping tools or awkwardly repositioning your hand just to reach the plug.
