ATEK Spark Plug Socket Wrench Set - 16mm & 21mm

This set is compatible with cars and motorbikes that use 16mm or 21mm spark plugs. Always confirm your vehicle's specific spark plug size in its service manual.

This set is designed for use with the included T-handle. While adapters might exist, using them is not recommended as it may compromise leverage or damage the tool.

Wipe them clean with a dry cloth after use. For tougher grime, use a damp cloth and dry thoroughly immediately afterward to prevent corrosion.

Yes, the T-handle slides onto the drive post of the sockets, allowing for easy attachment and removal.

The stainless steel construction provides excellent durability, resistance to corrosion, and rust, ensuring a long lifespan for the tools even in demanding workshop conditions.

This specific set includes 16mm and 21mm sockets. Please refer to other ATEK product listings for sets with different or additional sizes.

Verify that you are using the correct size (16mm or 21mm) for your vehicle's spark plug. Ensure no debris is obstructing the socket or plug.

Ensure the socket is fully and correctly seated onto the T-handle's drive post. Check for any damage to the drive post or socket interior.

Apply penetrating oil to the spark plug threads and allow it to soak. Use steady, even pressure with the T-handle. If still difficult, consider using a longer extension or a ratchet with a socket adapter if clearance allows (sold separately).

Immediately clean the affected area with a soft wire brush or steel wool. Apply a light coating of oil to prevent further rusting. Ensure the tool is stored in a dry environment.
