Spark Plug Socket 1/2" 19 mm Proxxon PR23445

Proxxon PR23445 is a 19 mm spark plug socket with a 1/2" (12.7 mm) drive designed for removing and installing spark plugs in automotive and small-engine applications. The tool provides a secure fit on standard 19 mm spark plug hexes and is intended for use with 1/2" drive ratchets or extensions to ensure reliable torque transfer and controlled access in recessed plug wells.

Advantages

The socket is manufactured to Proxxon quality standards for durability and dimensional accuracy, delivering firm engagement with the plug hex to reduce rounding and slippage. Its 1/2" drive interface allows use with common ratchets and extensions, giving leverage for tight or corroded plugs. The 19 mm size matches widely used spark plug dimensions, making the tool a straightforward, single-piece solution for service tasks.

Suitable for

• Removing and installing 19 mm spark plugs in cars and motorcycles
• Maintenance of small engines and garden equipment with 19 mm plugs
• Workshops and mobile tool kits that use 1/2" drive tools
• Accessing spark plugs located in recessed or tight engine spaces when paired with extensions

Key specifications

• Socket size: 19 mm hex
• Drive size: 1/2" (12.7 mm)
• Intended use: spark plug removal and installation
• Compatibility: standard 19 mm spark plug hexes and 1/2" drive ratchets/extensions
• Material and finish: manufactured to professional tool standards for strength and wear resistance

How to use

Select a 1/2" drive ratchet or extension and attach the 19 mm spark plug socket. Ensure the engine is cool before beginning work. Fit the socket squarely onto the spark plug hex, then turn the ratchet counterclockwise to remove the plug or clockwise to install. Use steady, controlled force to avoid cross-threading; when installing, start threading by hand where accessible and finish tightening with the ratchet to the vehicle manufacturer's specified torque.

Usage recommendations

Store the socket in a clean, dry toolbox and inspect for wear before use. Use proper torque settings and extensions as needed to access recessed plugs; when working on sensitive engines, consider a torque wrench on the 1/2" drive to achieve accurate tightening.
