Thinkpro Spline Lug Nut Socket Set, 6/7/10 Spline Key Kit — Thin-Walled, Heat-Treated Wheel-Friendly

Whether you're a DIYer changing tires at home or a professional mechanic working on vehicles with aftermarket wheels, the Thinkpro set gives you the right spline sizes in a single, ready-to-use package. The kit covers multiple spline counts and diameters used on many small cars, SUVs and trucks, and features a thin-walled, heat-treated construction to reduce the chance of wheel-surface marring while offering improved strength for repeated use.

Which spline sizes and diameters are included in this set?

The set combines three spline groups—6-spline, 7-spline and 10-spline—covering the most common aftermarket wheel lock designs. Exact socket sizes are stamped on each key so you can match them quickly to the lug nut specifications.

• 6-spline sockets: 41/64" and 45/64"
• 7-spline sockets: 3/4", 5/8", 11/16"
• 10-spline sockets: ta20-17/19, ta20-19/21, ta23-21/22

How does the dual hex drive design make removal easier?

Each key has a double hex drive head so you can use common lug wrenches or standard sockets to turn the key depending on what tool you have at hand. The dual-drive accommodates both 13/16" and 7/8" sockets, offering a tighter fit and better control during removal or installation.

• Dual hex drive fits 13/16" and 7/8" sockets
• Clear size markings reduce guessing and save time
• Works with standard lug-nut wrenches for quick field use

Is this socket set durable and wheel-friendly?

Construction uses heat-treated CR-MO42 alloy steel with an anti-cracking layer for improved strength under torque. The sockets are thin-walled to minimize contact with the wheel surface, helping prevent scratches or cosmetic damage when extracting tight or seized spline nuts.

• Heat-treated CR-MO42 steel core for durability
• Alloy anti-cracking layer to resist fracturing under load
• Thin-walled profile reduces risk of wheel scuffs

How do I know this set will fit my vehicle’s wheel locks?

Before buying, compare your wheel nuts to the spline count and spline diameters listed for the set. This kit only fits 6-, 7- and 10-spline wheel nuts—if your wheels use a different spline type or a one-off pattern, this set will not match.

• Check the lug nut spline count (6, 7 or 10) on your wheels
• Verify spline diameters against the listed socket sizes
• Refer to wheel or vehicle documentation if unsure

Who is this for? The Thinkpro Spline Lug Nut Socket Set is intended for vehicle owners, mobile tire technicians and garage mechanics who encounter aftermarket spline lug nuts regularly. It’s a practical addition to a roadside kit or workshop toolbox for anyone needing a compact, multi-size solution that balances strength with wheel-protective design. If you don’t know your spline type, measure before purchasing to ensure compatibility; if you frequently service different wheel types, this set covers many of the most common aftermarket spline configurations.
