Builimeer Spline Lug Nut Socket Set — 8-Piece Chrome-Moly Kit with Black Oxide Case, Fits Cars/SUVs

Builimeer Spline Lug Nut Socket Set is an 8-piece chrome-moly kit designed to remove a wide range of spline-style locking lug nuts quickly and without damaging wheels.

Keep a reliable tool on hand for wheel and tire work: this compact set includes multiple spline sizes to fit common anti-theft lug nuts, plus a tough carrying case for organized storage. Built from chrome-moly steel with a black oxide finish, the sockets resist corrosion and reduce cosmetic harm to rims while giving you the leverage and fit needed to extract damaged, rounded, or seized wheel locks. The set is sized for cars, SUVs, vans, and light trucks and is compatible with most standard lug wrenches, breaker bars, and impact tools.

Which lug nut spline types and sizes are included?

The set covers popular spline configurations so you can tackle a variety of wheel locks without buying separate keys. It includes tools for 12-, 7-, 6-, and 5-spline lug nuts in several common fractional sizes used on passenger vehicles.

• 12-spline: 13/16" and 11/16"
• 7-spline: 3/4", 5/8", 11/16"
• 6-spline: 41/64" and 45/64"
• 5-spline: 5/8"

How durable is the socket set for repeated use?

These sockets are manufactured from chrome-moly (chromium-molybdenum) steel, a material known for strength and toughness under torque. A black oxide coating helps prevent surface corrosion and minimizes scratching to wheel finishes when extracting lug nuts.

• High-strength chrome-moly construction for long life
• Black oxide finish for corrosion resistance and reduced marring
• Heat-treated and machined for consistent fit under load

Can the Builimeer set remove damaged or seized lug nuts?

Yes — the spline sockets are shaped to engage stripped, rounded, rusted, or frozen lug nuts more effectively than standard hex sockets. Their internal spline profile bites into the nut so you can apply steady torque and remove problem locks without grinding wheel faces.

• Designed to grip rounded or partially stripped lock nuts
• Works on rusted or frozen wheel locks when used with appropriate leverage
• Compatible with impact tools when extra force is required

How portable and user-friendly is this kit for roadside or garage use?

The eight sockets are stored in a compact, molded case that keeps each piece organized and ready to use. The set’s sizes are labeled and positioned for quick access, making it convenient to carry in a trunk or tool bag for on-the-road repairs.

• Sturdy molded case for neat storage and transport
• Fits most lug wrenches, breaker bars, and impact drivers
• Lightweight and compact for garage or travel use
