BILITOOLS Spark Plug Socket Set 7pc, 3/8" Drive — Magnetic 360° Swivel Sockets & Gap Tool, Chrome-Vanadium

The BILITOOLS 7-piece Magnetic Swivel Spark Plug Socket Set with gap tool is a compact, chrome-vanadium kit that secures, measures and removes spark plugs in tight engine spaces using a 3/8" drive and 360° swivel sockets.

This kit combines four common spark plug socket sizes, a precision gap gauge, and swiveling magnetic sockets to help you service ignition components quickly and with better access. Built from chrome-vanadium steel with a mirror chrome finish and supplied in a molded storage case, the set is intended for hobbyists and professional mechanics who need reliable tools that resist corrosion and stay organized.

Which spark plug sizes are included and why do they matter?

The set includes 9/16" (14mm), 5/8" (16mm), 14mm, and 16mm sockets to cover most common spark plug hex sizes found on cars, motorcycles and small engines. Having multiple sizes eliminates the need to improvise with ill-fitting tools that can round plug hexes.

• Sizes: 9/16", 5/8", 14mm, 16mm for broad compatibility.
• Clearly engraved markings for fast size selection.
• 6-point and 12-point profiles to match different plug designs.

How does the magnetic swivel feature improve spark plug removal?

Each socket contains a strong magnetic core that holds the spark plug in place, preventing drops when extracting plugs from deep wells. The 360° swivel allows angled access, letting you work around engine components without forcing the socket or risking damage to the plug.

• Magnetic retention reduces dropped plugs during removal and installation.
• 360° swivel helps reach plugs behind wiring, manifolds, or braces.
• Secure grip from 6- and 12-point profiles prevents rounding.

What does the included gap tool measure and how precise is it?

The dedicated spark plug gap tool provides both SAE and metric measurements for setting correct electrode gaps. It covers a wide range of sizes so you can check and adjust gaps to manufacturer specifications for most gasoline engines.

• SAE readings: 0.25" to 0.6" in common increments for imperial specs.
• Metric readings: 0.64mm to 1.52mm for metric plug specifications.
• Compact plate design keeps measurements consistent and repeatable.

How durable and portable is the kit for regular shop use?

Made from chrome-vanadium steel with a mirror chrome-plated finish, the sockets resist rust and oil corrosion and are simple to wipe clean after use. The molded storage case holds each piece securely and is engraved for quick identification, making the set easy to transport between jobs.

• Chrome-vanadium construction for strength and longevity.
• Mirror chrome plating to resist corrosion and ease cleaning.
• Sturdy molded case with engraved size markings for organization.
