Spark Plug Socket Set 16mm & 21mm Flexible T-Bar 3/8in Drive

A spark plug socket set for removing and fitting plugs during routine servicing and repair work. It includes 16mm and 21mm spark plug sockets with a flexible 3/8in drive T-bar handle, giving better access where engine bays or covers leave limited working room.

Used for vehicle maintenance, garage jobs and home servicing, this set suits both larger vehicle engines and smaller petrol engines where spark plugs need regular attention. The 16mm socket is suitable for many smaller engines such as motorcycles, mowers and outdoor power equipment, while the 21mm socket covers larger applications found on many cars and other vehicles. For DIY repairs or trade servicing, the flexible handle helps when plugs sit at an angle or lower down in tighter engine spaces.

Made from chrome vanadium steel, the set is built for repeated use and everyday workshop handling. The T-handle gives a steady grip and useful leverage when loosening older plugs or tightening replacements carefully during fitting. Its universal joint allows the handle to work at awkward angles, which can make access easier without needing a straight run onto the plug. With two common socket sizes included, it helps cover a useful range of spark plug service work while keeping the right tool close to hand for regular maintenance.
