dynofit Spline Lug Nut Socket Set 10pc — 1/2" Drive Impact Sockets for 5/6/7/10/12-Spline & Hex, CR-V Durable

Dynofit Spline Lug Nuts Socket Set (10 pieces) is a ready-to-use 1/2" drive impact socket kit built to remove and install 5/6/7/10/12-spline and hex spike tuner lug nuts without adapters.

Whether you’re a mechanic or a weekend enthusiast, this complete set brings the most common spline and spike lug nut sizes together in one heavy-duty kit. Each socket has a built-in 1/2" square drive so you can attach directly to an impact wrench. The CR-V construction, black electrophoretic finish, and precision-machined teeth improve durability and reduce slip during high-torque work.

Which lug nut styles and sizes are included in this set?

The kit covers a broad range of aftermarket tuner nuts: 5-, 6-, 7-, 10-, and 12-spline patterns plus common spike/hex styles. It includes both shallow and deep sockets for flush and extended nuts, so you can tackle most wheel designs without searching for individual keys.

• 7 standard spline sockets: 5-spline 3/4", 6-spline 45/64" & 41/64", 10-spline 13/16" & 23/32", 12-spline 13/16" & 11/16"
• 2 deep spike/hex-compatible sockets: 19mm SAE and 7-spline 3/4" deep socket
• Includes one extension bar for recessed nuts and hard-to-reach bolt seats

Can I use these sockets directly with an impact wrench?

Yes — every socket in the set has an integrated 1/2" square drive, eliminating the need for adapter pieces. This direct-drive design saves time, reduces connection play, and improves load transfer from the impact to the socket under heavy torque.

• Built-in 1/2" square drive for direct attachment to impact wrenches
• Fits common 1/2" impact tools used in shops and home garages
• Extension bar included for recessed or deep-mounted lug nuts

How durable and corrosion-resistant are these sockets?

Dynofit forged these sockets from chrome vanadium (CR-V) steel and heat-treated them for impact duty. A black electrophoretic coating protects against rust and chemical exposure, and every piece passes an extended 72-hour salt spray test to verify long-term resistance.

• Cold-forged CR-V steel withstands high torque without cracking
• Black electrophoretic finish reduces corrosion and surface wear
• 72-hour salt spray testing for extended outdoor and shop use

How does the design reduce slipping and protect wheel finish?

Each socket is precision-machined so the teeth engage spline and spike lug nuts accurately, lowering the chance of rounding or slippage. The deep sockets fit over long, tapered nuts while shallow sizes work for flush installations—both limit wobble that can damage wheel finishes.

• Precision-cut teeth for secure engagement with spline profiles
• Deep and shallow profiles protect wheel surfaces and nut heads
• Reduced slip minimizes cosmetic and mechanical damage during removal

Who this set is for: If you regularly service aftermarket wheels, remove lost lock keys, or perform tire rotations and brake work, this Dynofit 10-piece spline lug nut set is a practical addition to your toolbox. It suits professional shops, mobile mechanics, and DIYers who want a reliable, impact-rated solution for a wide range of spline and spike lug nuts—without hunting for separate adapters or specialty keys.
