TecoTek Magnetic Spark Plug Socket Set 5-Piece — 3/8" Drive, 14mm & 16mm Thin-Wall + 9/16"–13/16", Strong Magnet

TecoTek’s 5-piece magnetic spark plug socket set is a compact professional-grade kit that secures, protects, and removes spark plugs quickly using a 3/8" drive and heavy-duty magnet.

Whether you work on cars, ATVs, lawn equipment, or small engines, this TecoTek set combines thin-wall 14mm and 16mm sockets with 9/16", 5/8" and 13/16" options so you can reach recessed plugs and handle common thread sizes. Each socket is forged from heat-treated chrome vanadium (CR-V) steel, finished with a corrosion-resistant mirror polish, and stored in a fitted case for portability and organization. The built-in magnet replaces fragile rubber cups and helps retain spark plugs during removal or installation.

How does the magnetic core improve spark plug changes?

The heavy-duty magnet holds the spark plug securely in the socket so you don’t drop porcelain or damage electrodes while guiding plugs into tight wells. Unlike rubber inserts that deform over time, the magnetic retaining system remains effective and resists wear. This makes plug swaps faster and reduces the risk of broken or dropped plugs deep in the engine.

• Strong internal magnet for consistent retention
• No rubber gasket to compress or fail over time
• Protects the spark plug during removal and installation
• Works well in recessed or angled spark plug wells

Which vehicles and tasks are covered by this socket assortment?

The five sockets include two thin-wall metric sizes (14mm, 16mm) and three fractional sizes (9/16", 5/8", 13/16") that cover most automotive and small-engine spark plugs. Thin-wall sockets ease access in tight spaces where standard sockets won’t fit, while the 6- and 12-point options provide secure engagement on hex heads. This kit suits routine tune-ups, diagnostics, and roadside repairs.

• Cars, trucks, motorcycles, ATVs, lawn mowers, and generators
• Recessed spark plug wells accessible with thin-wall sockets
• Both metric and SAE spark plug hex sizes included
• Compatible with 3/8" drive ratchets and extensions

How durable and precise are the sockets for repeated shop use?

TecoTek forges each socket from heat-treated chrome vanadium steel, then polishes to a corrosion-resistant finish to withstand frequent use and exposure to grime. The 6-point and 12-point openings minimize rounding and slipping, giving a reliable fit on hex nuts. The set meets ANSI performance expectations and includes a one-year quality guarantee for added confidence.

• Heat-treated CR-V steel construction for strength
• Mirror polish finish to resist rust and corrosion
• 6-point and 12-point geometries reduce rounding
• Backed by a one-year quality guarantee

What’s included and how is the set stored for easy use?

The kit bundles five magnetic spark plug sockets in a molded storage case that keeps pieces organized and easy to transport. Each socket is clearly sized for quick identification while the case fits into a toolbox or trunk. The compact layout keeps sockets secure and prevents loss between jobs.

• Five sockets: 14mm, 16mm (thin-wall, 12-point), 9/16", 5/8", 13/16" (6-point)
• Durable heavy-duty plastic case for storage and transport
• 3/8" drive compatibility with standard ratchets and extensions
• Easy, labeled organization for fast access
