TecoTek magnetic spark plug socket set — 5-piece 3/8" drive, CR-V sockets with enhanced magnet retention

The TecoTek 5-piece 3/8-inch drive magnetic spark plug socket set is a professional-grade kit with heavy-duty magnets and a mix of 6- and 12-point CR-V sockets to hold, protect, and install spark plugs quickly and securely.

Whether you're changing plugs on a home garage project or servicing fleet vehicles, this compact set brings durable materials and practical sizes to one organized case. Each socket is forged from heat-treated chrome vanadium steel with a corrosion-resistant mirror polish, and the magnetic cores replace fragile rubber gaskets to retain plugs reliably during removal and installation.

Which socket sizes are included and why those matter?

This kit contains five sockets that cover the most common domestic and import spark plug hex sizes. The set mixes 6-point (9/16", 5/8", 13/16") and 12-point thin-wall (14mm, 16mm) designs so you can match factory fastener profiles and reach recessed plugs.

• 9/16-inch, 5/8-inch, 13/16-inch — 6-point sockets for high-torque, anti-slip engagement.
• 14mm and 16mm — 12-point thin-wall sockets for tight spaces and European/Asian fitments.
• 3/8-inch drive — compatible with common ratchets and extensions for workshop use.
• Magnetic core — holds the plug in place for removal without dropping in confined wells.

How does the magnetic design improve spark plug handling?

Instead of a rubber insert that degrades, TecoTek uses a strong integrated magnet to capture the spark plug and keep it seated while you maneuver the socket. This reduces dropped plugs and simplifies both extraction and reinstallation, especially in deep or awkward plug wells.

• Durable magnetic core — maintains holding power over time.
• Protects porcelain and threads — eases gentle reinstallation.
• Eliminates brittle rubber gaskets — better longevity in dirty garages.
• Works well with extensions and swivel joints for hard-to-reach plugs.

Are these sockets strong enough for professional use?

Yes — each socket is manufactured from heat-treated chrome vanadium (CR-V) steel and finished with a corrosion-resistant mirror polish to withstand shop environments. The 6- and 12-point geometries are designed to minimize rounding and slipping while meeting common ANSI durability expectations.

• Heat-treated CR-V steel — improves toughness and wear resistance.
• Mirror polish finish — helps resist rust and oil buildup.
• 6-point sockets for torque-heavy tasks; 12-point thin-wall for clearance challenges.
• Set packaged in a heavy-duty case for transport and storage.

What accessories and guarantees come with the set?

The sockets ship in a molded heavy-duty storage case that keeps each piece organized and protected. TecoTek backs the set with a one-year quality guarantee and builds the kit to exceed common performance standards, making it suitable for both DIYers and mechanics.

• Molded storage case — neat, portable, and protects tools in a toolbox.
• Meets or exceeds ANSI performance standards — for workshop reliability.
• One-year quality guarantee — support for manufacturing defects.
• Compact footprint — fits standard tool chests or mobile toolboxes.

Who is this for: The TecoTek 5-piece magnetic spark plug socket set fits home mechanics, professional technicians, fleet maintenance crews, and anyone who needs reliable plug removal and installation without damaged ceramics or dropped parts. It’s especially useful when working in tight engine bays or with mixed vehicle fleets that require both metric and SAE hex sizes.
