Siapupy Lug Nut Socket Set — 8-Piece Spline Wheel Lock Removal Kit, Black Oxide Case

The Siapupy 8-piece spline lug nut socket set is a heavy-duty wheel lock removal kit designed to remove a wide range of aftermarket and factory locking lug nuts quickly and reliably.

Whether you're a professional mechanic or a DIY vehicle owner, stripped, rusted or non-matching wheel locks can delay tire changes and maintenance. This kit gathers multiple spline sizes in one compact, organized case so you can identify and remove problem lug nuts without buying single, expensive specialty sockets. It blends forged chrome-moly construction, a protective finish and clear size markings to make roadside or shop removal more efficient.

Which lug nut types and sizes are included in the Siapupy kit?

The set covers common spline patterns and diameters so you can match most aftermarket wheel locks and factory splined nuts. Check your wheel lock's spline count and nut diameter before use to confirm compatibility.

• 7-spline: 3/4" (19 mm), 5/8" (16 mm), 11/16" (17 mm)
• 12-spline: 13/16" (21 mm), 11/16" (17 mm)
• 6-spline: 41/64" (16.3 mm), 45/64" (17.9 mm)
• 5-spline: 5/8" (16 mm)

How does this set help remove damaged or rusted wheel locks?

Each socket is machined to engage splines precisely, reducing slippage on rounded or corroded nuts. The robust profile transfers torque efficiently, enabling extraction of seized or stripped locks when conventional sockets fail.

• Precision internal spline fits worn lug nut profiles
• Heat-treated chrome-moly steel withstands high torque
• Black oxide finish resists corrosion and surface wear
• Laser-engraved markings speed selection under low light

What materials and design features make this set durable?

Siapupy builds the sockets from heat-treated chrome-moly for toughness and fatigue resistance during heavy use. A black oxide coating adds corrosion protection and minimizes marring, while careful machining ensures long-term dimensional accuracy.

• Forged chrome-moly construction to reduce cracking risk
• Black oxide surface finish for rust resistance and scratch protection
• Accurate CNC machining for repeatable spline engagement
• Compact blow-molded case to protect tools during transport

How do I store and pick the right key quickly?

The included rugged storage case keeps each socket organized and labeled so you can identify the correct key at a glance. Laser-engraved size markings and dedicated slots prevent lost pieces and simplify inventory after a job.

• Blow-molded case holds each socket securely in place
• Laser-engraved labels for fast visual identification
• Compact footprint fits in a service drawer or trunk
• Case protects finishes and prevents rattling during transport

Who is this for: The Siapupy 8-piece spline lug nut socket set suits automotive technicians, mobile tire services, fleet managers and hands-on vehicle owners. If you encounter aftermarket wheel locks, stripped lug nuts, or service needs across multiple vehicles, this kit provides a practical, durable solution without buying individual specialty sockets.
