WORKPRO 3/8" Drive Magnetic Spark Plug Socket Set — 6-Piece Thin-Wall 12-Point with 360° Swivel

WORKPRO's 3/8" drive 6-piece magnetic spark plug socket set is a compact, corrosion-resistant kit that combines a 360° swivel, thin-wall 12-point sockets and built-in magnets to remove and install spark plugs in tight engine bays with confidence.

This set brings six purpose-built sockets and extensions to one compact kit, engineered for mechanics and DIYers who need reliable access to spark plugs across cars, motorcycles, trucks and small engines. Built from hardened steel with a black phosphate finish and laser-etched sizes, the kit trades bulk for versatility: long and short lengths plus a swivel head tackle awkward angles while the magnetic cores prevent dropped plugs.

How does the 360° swivel make spark plug work easier?

The full 360° swivel allows the socket to pivot freely when working around obstructions, so you don’t have to fight the drive or reposition the ratchet constantly. That motion reduces wrist strain and helps you reach plugs behind manifolds or brackets.

• 360° swivel head for unrestricted pivoting in tight engine compartments
• Smoother alignment with the plug to reduce cross-threading risk
• Faster removal and installation in confined spaces

Why choose thin-wall 12-point sockets for spark plugs?

The 1 mm thin-wall construction slips into narrow plug wells where thicker sockets can't fit, while the 12-point profile gives more contact positions for easier engagement with fasteners. This combination improves access and reduces the chance of rounding the plug hex.

• 1 mm thin walls for narrow spark plug wells
• 12-point geometry for improved grip and multiple engagement angles
• Reduced interference with adjacent components and wiring

How does the magnetic core protect plugs during service?

Each socket is equipped with a built-in magnet that holds the spark plug securely, preventing drops and scratches when extracting or inserting plugs in awkward positions. The magnetic grip keeps porcelain and electrodes steady so you can seat or remove plugs confidently.

• Integrated magnet prevents plug drops in deep wells
• Steady placement reduces the risk of porcelain damage
• Hands-free holding simplifies alignment during installation

What sizes are included and when would I need the extensions?

The six-piece set includes a range of commonly used spark plug socket sizes in both long and short lengths to cover most vehicles and small engines. Use the short sockets where access is easy and the long versions or extensions for recessed plugs or when maneuvering around intake components.

• Included sockets: 14mm (4"), 9/16" (6"), 5/8" (4", 6", 11"), 13/16" (6")
• Short sockets for tight clearances, long sockets for recessed plugs
• Extensions and swivel combine to reach obstructed plugs without disassembly

Built from premium steel with a corrosion-resistant black phosphate finish and laser-etched size markings, this set balances durability and clear identification. The thin-wall construction, magnetic cores and swivel feature work together to make spark plug replacement faster and less error-prone for pros and hobbyists alike.

Who is this for? This WORKPRO spark plug socket set is designed for professional mechanics, mobile technicians and home mechanics who service cars, motorcycles, ATVs, light trucks and lawn equipment. It’s especially useful when engine designs put plug openings behind brackets, manifolds or deep wells and when you want a compact, durable kit that prevents dropped plugs and speeds up routine maintenance.
