21mm 3/8” Drive 12pt CR-V 250mm Extra Long Thin-Walled Spark Plug Socket- PKTool
The PKTool 21mm 3/8” Drive Extra Long Spark Plug Socket is specifically designed for safe and efficient removal and installation of spark plugs in deep or restricted engine bays. Featuring a 250mm extra-long length, this socket provides extended reach for hard-to-access spark plug wells commonly found in modern engines.
Manufactured from high-strength Chrome Vanadium (CR-V) steel, this socket is built for durability and reliable torque transfer under workshop conditions. The thin-walled design with a 27.5mm outer diameter allows clearance in tight plug tubes, reducing the risk of contact with cylinder head walls. The 12-point (12PT) configuration ensures secure engagement with spark plugs, while the integrated magnetic plug holder safely retains the spark plug during removal and installation.
Ideal for professional workshops and serious DIY mechanics, this spark plug socket delivers precision, reach and reliability.
