Siapupy 8-Piece Spline Lug Nut Socket Set — 6 & 7-Spline Wheel Lock Removal, Chrome-Moly with Storage Case

Siapupy's 8-piece spline lug nut socket set is a heavy-duty wheel lock removal kit that removes 5-, 6-, 7- and 12-spline aftermarket and factory lug nuts quickly and stores securely in a rugged case.

Whether you’re a weekend DIYer or a professional mechanic, this complete set gives you the range of spline sizes and durable construction needed to tackle corroded, stripped or locked lug nuts. Built from heat-treated chrome-moly steel with a black oxide finish, each socket is sized and laser-engraved for fast identification and protected inside a blow-molded storage case. The kit covers multiple spline patterns and diameters so you can match keys to most common wheel locks without buying individual tools.

Which wheel lock and spline types does this kit work with?

The Siapupy kit includes master keys that fit a wide variety of spline patterns and nut diameters used on aftermarket and factory wheels. It covers 7-spline, 12-spline, 6-spline and 5-spline configurations with specific sizes to match common lug nut diameters. Inspect your wheel lock pattern and nut diameter to pick the correct socket before use.

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

How durable and reliable are the sockets under heavy use?

Each socket is forged from heat-treated chrome-moly steel to resist cracking and deformation during high-torque removal. The black oxide finish improves corrosion resistance and guards against surface wear, extending service life even in harsh garage environments. These materials and finishes make the set suitable for repeated professional use.

• Heat-treated chrome-moly construction for strength
• Black oxide finish to reduce rust and scratching
• Designed to endure high torque without shearing
• Laser-engraved sizing to prevent mix-ups

How does this set make lug nut removal easier and faster?

The kit is intended to remove stubborn, damaged or stripped wheel locks by matching the correct spline key to the lug nut profile. That precise fit prevents further rounding and allows conventional impact wrenches or breaker bars to apply torque more effectively. Quick visual identification and organized storage cut setup time during tire changes or brake work.

• Master keys match common spline patterns to prevent slippage
• Works with impact tools and hand wrenches for versatility
• Rugged blow-molded case keeps parts organized and transportable
• Laser size markings speed tool selection
