LLNDEI Magnetic Swivel Spark Plug Socket Set 12-Piece 3/8-inch Drive — Chrome-Vanadium, 360° Access

LLNDEI 3/8-inch drive magnetic swivel spark plug socket set is a 12-piece, chrome-vanadium toolkit designed to remove and install spark plugs in tight or awkward engine spaces with magnetic retention and a 360° swivel feature.

This comprehensive set brings six rotatable magnetic sockets in multiple lengths and common spark plug sizes, built from heat-treated Chrome Vanadium Steel with a polished chrome finish. It’s made for home mechanics, professional technicians, and anyone who needs reliable grip and reach when changing spark plugs. The kit pairs magnetic retention with a thin-wall, 12-point configuration so plugs seat securely and tools fit into compressed engine compartments.

How does the magnetic swivel design help during spark plug changes?

The built-in magnet holds the spark plug firmly in the socket so you can guide and start threads without dropping the plug deep inside the cylinder. The 360° swivel head lets you approach the plug from odd angles, reducing the need to contort your arm or remove nearby components.

• Integrated powerful magnet secures plug for one-handed insertion.
• 360-degree swivel improves access in tight engine bays.
• Thin-wall sockets fit between braces and narrow openings.

Which socket sizes and lengths are included for different vehicles?

The set contains six sizes commonly used on cars, trucks, motorcycles, and lawn equipment. Multiple lengths—4-inch, 6-inch, and an 11-inch extension—cover deep-reach plugs and shallow access points, so you can pick the right combination for the job.

• 14 mm 4-inch, 5/8" 4-inch—short reach for compact engines.
• 9/16" 6-inch, 5/8" 6-inch, 13/16" 6-inch—medium reach for most vehicles.
• 5/8" 11-inch—extra reach for recessed spark plugs.

What construction and finish protect the sockets from wear?

Each socket is forged from heat-treated Chrome Vanadium Steel to withstand high torque and repeated use. A chrome-plated mirror finish resists rust and oil, making cleaning easier and keeping size markings clear for fast identification.

• Heat-treated chrome-vanadium steel for durability.
• Polished chrome plating reduces corrosion and simplifies cleaning.
• Laser- or stamped size markings speed socket selection.
