Spark Plug Socket 16 mm 1/2" Drive 64 mm Proline 18546

Proline spark plug socket 16 mm with 1/2" drive and 64 mm length is a hand tool designed for removal and installation of spark plugs in engines where additional reach is required. The tool combines a 16 mm socket profile with a 64 mm tube length to access recessed spark plugs and is compatible with standard 1/2" ratchets and extensions used in automotive maintenance and workshop environments.

Advantages

The 16 mm profile matches common spark plug hex sizes for secure engagement and reduced rounding risk. With a 64 mm length and 1/2" drive interface, the socket provides improved access to deep-set plugs while remaining compatible with widely used ratchet drives and extensions. The construction is intended for frequent workshop use, offering reliable fit and straightforward operation for technicians and DIY users.

Suitable for

• Removal and installation of spark plugs in passenger cars and light commercial vehicles
• Workshops and professional repair shops requiring extended-reach tools
• Routine automotive maintenance and servicing tasks
• Use with 1/2" ratchets, torque wrenches and extension bars

Key specifications

• Socket size: 16 mm
• Drive size: 1/2" (12.7 mm)
• Overall length: 64 mm
• Designed for spark plug access in recessed locations
• Material and finish: workshop-grade metal construction suitable for repeated use

How to use

Select a compatible 1/2" ratchet or extension and attach the spark plug socket. Ensure the engine is cool and the ignition system is disabled before starting work. Position the socket over the spark plug, engage fully to avoid slipping, and turn counterclockwise to loosen the plug. When installing a new spark plug, thread it by hand first to avoid cross-threading, then tighten with the appropriate torque using a torque wrench or ratchet according to the vehicle manufacturer's specification.

Usage recommendations

Use the socket with a suitable extension when access is restricted; avoid excessive force that can damage spark plugs or threads. Inspect the socket and drive connection for wear before each use and follow vehicle-specific torque values to ensure proper sealing and long-term reliability.
