TecoTek Magnetic Spark Plug Socket Set 10-Piece — 3/8" Drive, 14–18mm & 9/16"–5/8" with Swivel, Extension & Universal Joint

This toolkit bundles multiple hex sizes, a swivel magnetic socket pair, a universal joint and a long extension bar so you can reach plugs in tight engine bays without dropping or damaging the plug. Made from heat-treated chrome vanadium steel with a corrosion-resistant polished finish, the set combines durability with smooth operation for both home mechanics and technicians.

Which sockets are included and why do their sizes matter?

The kit covers the most common spark plug hex sizes across cars, light trucks and motorcycles: 9/16" and 5/8" plus metric sizes up to 18mm. Two 12-point and five 6-point sockets ensure a snug fit that reduces rounding and slips.

• 2-piece 12-point magnetic swivel sockets: 14mm and 16mm for restricted-access plugs.
• 5-piece 6-point magnetic sockets: 9/16", 5/8", 3/4", 13/16", 18mm for common plug sizes.
• Universal joint and 10" extension let you work around obstructions and deep-set plugs.
• Spark plug gapper included for basic servicing and verification.

How does the magnetic design help when changing spark plugs?

Each socket contains a strong magnetic core that holds the plug in place during removal and reinstallation, preventing drops and reducing the risk of damaging ceramic insulators. Unlike soft rubber retainers, the magnetic system maintains its grip over time.

• Secure retrieval of plugs from deep wells or awkward angles.
• Prevents plug drops that can chip porcelain or strip threads.
• Consistent performance without rubber deterioration.

Can I use these sockets in tight or angled engine compartments?

The set includes a swivel magnetic socket and a universal joint to provide the articulation needed for restricted spaces. The slim socket profiles and 3/8" drive reduce bulk, making it easier to access plugs behind manifolds or obstructing components.

• Swivel sockets pivot for angled entry and removal.
• Universal joint bridges offsets and uneven access paths.
• 10" extension reaches recessed plugs without disassembly of surrounding parts.

What build quality and storage features does the kit offer?

Each piece is forged from heat-treated chrome vanadium (CR-V) steel, polished to resist corrosion and finished for long life under workshop conditions. The included heavy-duty case keeps sockets organized and portable between jobs.

• Heat-treated CR-V construction for strength and wear resistance.
• Mirror-polish finish protects against rust and grime.
• Compact storage case keeps the set together and easy to transport.
• TecoTek tools meet ANSI performance expectations and include a one-year quality guarantee.

Who this set is for: Enthusiasts who perform routine tune-ups, mobile mechanics who need reliable, compact tools for varied vehicles, and DIYers who want a single kit that covers most spark plug jobs. If you need secure plug handling, flexible access in cramped engine bays, and a durable set that stays organized, this TecoTek 10-piece magnetic socket kit is a practical addition to your toolbox.
