Why You'll Love This Spark Plug Socket

• Fits 14mm & 16mm Spark Plugs — the two most common sizes found in modern petrol/gasoline engines, making this a true universal tool for most car owners.
• Magnetic Grip — the built-in magnet holds your spark plug securely inside the socket, so you can insert and remove plugs without them falling into the engine bay.
• Flexible Universal Joint — the swivel joint lets you change the working angle on the fly, making it easy to access spark plugs that are recessed, angled, or blocked by surrounding components.
• 12-Point Profile (Works on 6-Point Too) — the 12-corner design provides more engagement points for extra grip and reduced slipping, and it's fully compatible with 6-point sockets as well.
• Thin-Wall Construction — the slim profile fits into tight engine bays where bulkier sockets simply won't go.
• Chrome Vanadium Steel (CR-V) — hardened and heat-treated for long-lasting durability and resistance to rust and wear.

Frequently Asked Questions

Q: What size spark plugs does this magnetic spark plug socket fit?

A: This socket is designed to fit both 14mm and 16mm spark plugs, which are the two most common spark plug thread sizes used in the majority of petrol/gasoline passenger vehicles. The thin-wall design ensures compatibility even in tight, recessed engine bays.

Q: What is the universal joint used for on this spark plug socket?

A: The flexible universal joint allows you to change the angle of the socket while in use, making it much easier to reach spark plugs that are not in a straight line of access. This is especially useful in modern engines where components crowd the spark plug ports.

Q: Why does this spark plug socket have a magnet?

A: The built-in magnet holds the spark plug firmly inside the socket during installation and removal. This prevents the plug from falling into the engine bay — a common and frustrating problem with standard sockets — saving you time and effort.

Q: Is this socket compatible with a standard ratchet wrench?

A: Yes. This spark plug socket features a standard drive size compatible with common ratchet wrenches and extension bars. The 12-point profile also means it can be used with both 6-point and 12-point drive tools for maximum versatility.

Q: Is CR-V (Chrome Vanadium Steel) a good material for a spark plug socket?

A: Absolutely. Chrome Vanadium Steel (CR-V) is a professional-grade alloy widely used in hand tools due to its excellent strength, hardness, and resistance to corrosion and wear. It ensures this socket can handle repeated use without cracking or deforming.
