Magnetic Swivel Spark Plug Socket 9/16 x 6 Inch - GearWrench

The GearWrench 3938 Magnetic Swivel Spark Plug Socket is engineered for professional technicians working with modern engines that feature deep plug wells and restricted clearances. This specialized 9/16th spark plug socket combines secure magnetic retention with a true swivel head and thin-wall construction, enabling precise spark plug changes around crowded components and challenging bank angles. Designed for 3/8" drive systems, it ensures consistent engagement and access where conventional spark plug sockets may struggle.

Key Features

• Secure Magnetic Retention: A robust internal magnet securely holds the spark plug during both removal and installation, mitigating the risk of drops into the cylinder head or engine bay. This makes it a reliable 9/16 magnetic spark plug socket for technicians prioritizing positive retention.
• True Swivel Head Access: The full 360° swivel joint, paired with a 6-inch overall length, allows this 9/16 spark plug socket magnetic tool to maneuver effectively around hoses, brackets, and coil packs in confined engine compartments.
• Thin-Wall Construction: Engineered with a narrow profile, this socket easily clears tight plug tubes and deep wells where standard-wall sockets or extensions might obstruct access.
• 6-Point Off-Corner Loading: The 6-point profile engages the flats of the spark plug, distributing torque evenly to reduce the risk of rounding and potential plug damage, particularly on stubborn or previously serviced plugs.
• Durable Professional-Grade Steel: Constructed from resilient alloy steel with a protective chrome finish, it resists corrosion and wear inherent in daily shop use, ensuring longevity and easy cleaning.

Applications

This tool is well-suited for late-model vehicles requiring 9/16" plugs, including numerous Ford Triton and similar engines characterized by deep plug wells and limited access points. This 9/16th spark plug socket is a practical choice for general repair shops, dealer service departments, and fleet maintenance operations seeking repeatable, low-risk spark plug service in challenging engine configurations.
