Magnetic Spark Plug Socket Proxxon PR23394 1/2" Drive 18 mm

Magnetic spark plug socket Proxxon PR23394 1/2" Drive 18 mm is a compact workshop accessory designed for secure removal and installation of spark plugs in engines that accept an 18 mm socket and a 1/2" drive. The integrated magnetic insert holds the spark plug in place, reducing the risk of dropping or damaging the component during service. This socket is made to be used with common 1/2" drive ratchets, breakers or extension bars and is suitable for both workshop and field repairs on cars, motorcycles, lawnmowers and other small engines.

Advantages

The magnetic insert ensures a reliable retention of the spark plug during extraction and insertion, improving handling in confined engine compartments. The 18 mm size matches standard spark plug hex sizes, allowing direct engagement and controlled torque transfer when used with a 1/2" drive tool. Its compact construction and corrosion-resistant finish provide durability and ease of storage in a mechanic's toolkit.

Suitable for

• Removing and installing 18 mm spark plugs in passenger cars and light commercial vehicles
• Maintenance of motorcycles, scooters and all-terrain vehicles with 18 mm plugs
• Servicing small engines such as lawnmowers, generators and garden equipment
• On-site repairs where a 1/2" drive ratchet or breaker bar is available

Key specifications

• Socket diameter: 18 mm suitable for standard spark plug hex
• Drive size: 1/2" compatible with standard 1/2" ratchets and extensions
• Retention: integrated magnetic insert to hold the spark plug
• Construction: compact, single-piece socket designed for workshop use
• Finish: corrosion-resistant surface suitable for regular maintenance environments

How to use

Select a compatible 1/2" drive ratchet or extension and attach the 18 mm magnetic spark plug socket. Ensure the ignition is off and the engine is cool before beginning work. Carefully insert the socket over the spark plug until the magnetic insert engages and holds it. Turn the ratchet counterclockwise to loosen and remove the plug; the magnet will keep the plug secured to the socket. For installation, position the spark plug through the socket, start threading by hand to avoid cross-threading, and then tighten with the ratchet to the manufacturer's specified torque using an appropriate torque wrench where precise tightening is required.

Usage recommendations

Use the socket with appropriate torque control to avoid over-tightening. Keep the magnetic face free of heavy debris and inspect the socket for wear before each use. Store in a dry toolbox to maintain the corrosion-resistant finish and ensure reliable magnetic retention during future maintenance tasks.
