Spark Plug Socket Set 14mm 16mm 21mm 3/8in Drive 4pc

A 4-piece spark plug socket set for 3/8in drive ratchets, covering 14mm, 16mm and 21mm spark plug sizes, plus a 16mm thin wall socket. Made from chrome vanadium and built in a 63mm deep pattern, it is intended for secure spark plug removal and fitting without putting unnecessary strain on the plug.

Used for vehicle servicing, routine maintenance and spark plug replacement work, this set suits garages, workshops and home mechanics carrying out regular engine work. The included size range helps with common spark plug applications, while the thin wall 16mm socket is useful where access is tighter around the plug recess. For anyone working on different vehicles, having these sizes together helps avoid hunting around for individual sockets when service jobs come up.

The sockets are made from chrome vanadium for repeated workshop and garage use, with a 3/8in drive fit for use with compatible ratchets, extensions and related drive tools. A 63mm deep design gives the socket enough reach to sit properly over the plug, which can help with cleaner engagement during removal and refitting. The 4-piece set keeps the main sizes together in one place, making it easier to stay organised during servicing and general maintenance work.
