## Summary description

AWTools 21 mm spark plug socket from the Black Line series designed for removal and installation of spark plugs. The socket fits 21 mm spark plug hex sizes and is intended for automotive maintenance and engine service.

## Long description

AWTools 21 mm spark plug socket from the Black Line series is designed for safe and precise removal and installation of spark plugs in a variety of engines. The socket fits hex sizes of 21 mm and is intended for automotive maintenance and engine service, providing a compact and robust solution for access to spark plugs in tight spaces.
Advantages
The AWTools Black Line 21 mm spark plug socket is constructed to deliver consistent fit and torque transfer to the spark plug hex. Its 21 mm dimension matches standard spark plug hex sizes used in many cars and motorcycles. The socket’s design emphasizes durable contact with the plug head to reduce rounding and slippage during removal or installation. Its compact length improves access in restricted engine bays while maintaining sufficient strength for workshop and home use.
Suitable for
Removing and installing 21 mm spark plugs in passenger cars
Maintenance of motorcycles and small engines that use 21 mm spark plug hexes
Routine engine service and spark plug replacement in garage or mobile repair settings
Key specifications
Drive interface: fits common ratchet or extension tools (standard square drive size compatible with socket sets)
Socket hex size: 21 mm for standard spark plug hex dimensions
Series: Black Line designation for consistent product family finish and handling
Construction: engineered for workshop and DIY use with emphasis on strength and wear resistance
Length: compact design to access spark plugs in confined engine spaces
How to use
Select a compatible ratchet or extension with the appropriate square drive and attach the AWTools 21 mm spark plug socket. Align the socket over the spark plug hex and engage fully before applying torque. Use steady, controlled force when loosening or tightening to avoid cross-threading; when installing new plugs, follow the engine manufacturer’s recommended torque values or use a torque wrench. When working in confined areas, use extensions or universal joints as needed to reach the plug while maintaining a straight engagement to the hex.
Usage recommendations
Inspect the socket and fastener surfaces before use. Replace the socket if wear or deformation is visible. For precise installation, use a calibrated torque wrench and follow the engine maker’s torque specifications. Store the socket in a clean, dry tool case to preserve the finish and fit.
