Spark Plug Socket 14 mm 1/2" Jonnesway S17H4314

Jonnesway spark plug socket 14 mm with 1/2" drive (model S17H4314) is a hand tool designed to remove and install 14 mm spark plugs. The socket accepts a standard 1/2" ratchet or breaker bar, providing sufficient reach and torque for routine automotive maintenance and engine service tasks. Its size and drive type make it compatible with many passenger cars, light trucks and small engines where a 14 mm spark plug is specified.

Advantages

The tool combines a 14 mm hollow socket profile with a 1/2" square drive for secure engagement with ratchets and extensions. Its construction is intended to provide a firm fit on spark plug hexes while allowing attachment of common hand tools for turning and controlled torque application. The socket’s interior usually accommodates a rubber insert or magnetic element to retain the plug during removal and installation, reducing the risk of dropping the spark plug in tight engine bays.

• Removing and installing 14 mm spark plugs in passenger cars
• Engine maintenance on light trucks and vans with 14 mm plugs

How to use

Fit the 14 mm spark plug socket onto a 1/2" ratchet or breaker bar and, if needed, use an appropriate extension to reach the spark plug. Carefully engage the socket onto the spark plug hex to ensure a secure grip. Turn counterclockwise to loosen and remove the plug; when installing, start the plug by hand to avoid cross-threading, then tighten to the manufacturer’s specified torque using the ratchet or a torque wrench with the 1/2" drive.

Usage recommendations

Before use, confirm the engine is cool and the correct spark plug size is required. Where precise torque is important, use a torque wrench with a 1/2" drive to achieve the manufacturer’s recommended tightening specification. Store the socket in a tool case or on a rail to prevent loss and protect the retention element from damage.
