## Long description

Proline spark plug socket 21x64 mm with a 1/2" drive is a workshop tool designed for safe removal and installation of automotive spark plugs. The 21 mm internal size fits standard spark plugs while the 64 mm length reaches recessed plugs in modern engines. Made for use with a 1/2" drive ratchet or extension bar, this socket is intended for routine maintenance and repair tasks in garages and service shops.
Advantages
This spark plug socket combines a precise 21 mm fit with a 64 mm length to access deep-seated plugs without damaging the plug hex or surrounding components. The 1/2" drive interface provides robust torque transfer when used with compatible ratchets and extensions. The socket's design supports controlled handling during plug removal and installation, reducing the risk of stripping or cross-threading.
Suitable for
Removing and installing 21 mm spark plugs in passenger cars and light commercial vehicles
Accessing recessed spark plugs in engines with deep spark plug wells
Use with 1/2" drive ratchets and extension bars during maintenance and repair

Key specifications
Socket internal size: 21 mm
Socket length: 64 mm
Drive size: 1/2" (12.7 mm)
Intended application: spark plug removal and installation
How to use
Select a compatible 1/2" drive ratchet or extension and attach the socket securely. Ensure the engine is cool before starting work. Fit the socket squarely onto the spark plug hex and turn counterclockwise to loosen; use steady, controlled force to avoid damaging the plug or threads. After removing the spark plug, inspect the plug and thread condition, then install a new or serviced plug by hand to start threading and finish tightening with the ratchet, following the manufacturer’s torque recommendation for your engine.
Usage recommendations
For safe and reliable results, use the socket with matching 1/2" drive accessories and observe manufacturer torque settings for spark plug installation. When working in tight or deep wells, a thin-walled extension can improve access. Avoid applying excessive torque once the plug is seated to prevent thread damage.
