Siapupy Spline Lug Nut Removal Set - 8-Piece Chrome-Moly Sockets, Black Oxide Case for Damaged & Locking Lug Nuts

The Siapupy 8-piece spline lug nut socket set is a heavy-duty removal kit that safely extracts damaged, rusted, or aftermarket locking lug nuts from cars, trucks, SUVs and trailers.

This compact kit bundles multiple spline patterns and sizes into a durable, organized case so you can remove stubborn wheel locks without guessing which tool fits. Built from heat-treated chrome-moly steel with a black oxide finish, the set combines strength and corrosion resistance for repeated garage or roadside use. It includes common spline sizes needed for many aftermarket and factory wheels, making it a practical alternative to buying single replacement keys or expensive dealer services.

Which lug nut patterns and sizes are included?

The kit covers a range of spline and standard profiles so you can match the right key to your wheel’s locking pattern. Each socket is laser-engraved for quick identification, reducing trial-and-error during a tire change or repair.

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

How does this set handle damaged or rusted lug nuts?

Designed as a removal tool, the spline sockets grip stripped or corroded lug nuts more securely than generic sockets. The heat-treated chrome-moly construction resists deformation so the tool maintains its shape while you apply torque to extract stubborn locks.

• Deep spline engagement for damaged head surfaces
• Heat-treated steel reduces cracking and wear
• Black oxide finish improves corrosion resistance
• Fits common impact wrenches and breaker bars for extra leverage

Can I use this with my existing tools and on different vehicles?

Yes — sockets are sized to work with standard drive tools and fit a variety of vehicles, from compact cars to heavy trucks and trailers. The set is versatile enough for mechanics, mobile tire techs, and DIYers who service multiple vehicle types.

• Compatible with 3/8" and 1/2" drive adapters (as needed)
• Works on cars, SUVs, trucks, RVs and trailers
• Spline range covers many aftermarket and factory locking lug nuts
• Compact case fits in a mechanic’s toolbox or trunk for roadside use

What makes this set durable and easy to keep organized?

Each piece is forged from tough chrome-moly steel and given a black oxide finish to resist rust and surface wear. The blow-molded case keeps tools secure, labeled, and ready when you need them, so you spend less time searching and more time removing the lock safely.

• Heat-treated metal construction for longevity
• Black oxide finish resists corrosion and reduces scratches
• Laser-engraved size markings remain readable over time
