Spark Plug Socket 21mm X 65mm X 3/8'dr Crv

Size: 21mm x 65mm
Drive Type: 3/8" Square Drive
Profile Type: 6 Point

This specialized 21mm spark plug socket is purpose-built for the careful installation and removal of spark plugs in a variety of gasoline engines. Its dedicated design ensures a precise fit, which is crucial for preventing damage to the delicate ceramic insulator during maintenance.

The socket features an extended 65mm deep reach, allowing mechanics to easily access plugs that are recessed deep within the cylinder head or shrouded by engine components. This substantial depth overcomes common clearance issues encountered during routine engine tune-ups.

For robust performance, the socket is constructed from durable Chrome Vanadium (CrV) steel. This high-quality material guarantees longevity and provides the strength required to handle high-torque applications without cracking or warping, ensuring it stands up to repeated use in a professional or demanding DIY environment.

It operates on a standard 3/8-inch drive (DR), making it fully compatible with common ratchets, extensions, and universal joints. The 6-point (6PT) configuration is an essential feature, providing maximum surface contact and leverage on the spark plug's hex, which significantly minimizes the risk of rounding or damaging the plug during tightening or loosening.
