Thinkpro Spline Lug Nut Socket Set — 5/6/7/12 Spline Wheel Lock Removal Kit, CR-MO Heat‑Treated, Dual‑Hex

The Thinkpro Spline Lug Nut Socket Set is an 8-piece wheel lock removal kit engineered to remove 5-, 6-, 7- and 12-spline aftermarket lug nuts safely and without damaging wheels.

When an aftermarket wheel uses a proprietary spline-style locking lug, normal sockets won't work and replacements can be hard to find. This Thinkpro kit gathers the most commonly used spline sizes and diameters into one compact set, offering mechanics and DIYers a practical solution for removing or swapping aftermarket wheel locks. The set's dual-hex drive heads and heat-treated CR-MO42 steel construction prioritize fit, torque transfer and durability while minimizing the chance of scarring thin-wheel lips.

Which spline sizes and diameters are included in the kit?

The kit targets the most frequent spline variations encountered on aftermarket wheels: 5, 6, 7 and 12 spline patterns in several diameters. Each socket is sized to match common wheel lock profiles so you can pair the right key to the vehicle’s lug design.

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

How does the dual hex drive design help with removal?

Each key features a double hex head so it fits a range of common wrench and socket sizes, improving leverage and reducing slippage under load. Size markings on the head let you identify the correct key quickly, saving time in busy garages.

• Dual hex drive fits most lug-nut wrenches
• Compatible with 13/16" and 7/8" sockets for higher torque
• Clear size markings speed selection and reduce mistakes

What materials and construction protect wheels and withstand torque?

The keys are forged from heat-treated CR-MO42 steel and finished with an alloy anti-crack layer for greater strength and fatigue resistance. A thin-walled design helps the socket engage the splines without contacting or scraping the wheel barrel or lip, preserving wheel finish during removal.

• Heat-treated CR-MO42 steel core for strength
• Alloy anti-cracking layer to resist wear and stress
• Thin walls to avoid scratching or gouging wheel surfaces

When should I choose this universal wheel lock removal kit?

Pick this set when you don’t have the factory key or when aftermarket spline nuts prevent use of standard sockets. It’s designed as a multi-fit emergency and workshop solution, particularly useful when replacing wheels, changing tires, or rescuing seized locks.

• Use when original wheel-lock key is lost or damaged
• Ideal for aftermarket wheels with spline-style lug nuts
• Handy kit for mobile mechanics and at-home tire changes

Who is this for? The Thinkpro Spline Lug Nut Socket Set is intended for professional mechanics, tire technicians and vehicle owners who work with aftermarket wheels. If you frequently service multiple vehicles or keep a roadside tool kit, this set provides a broad range of spline keys so you’re ready for common spline-style wheel locks. Note: confirm your wheel lock's spline count and diameter before purchasing — this kit only fits 5, 6, 7 and 12 spline configurations in the listed diameters.
