1 Verify that lug nuts/bolts are the correct style as recommended by the wheel manufacturer, including the spare tire (i.e. flat seat, cone seat, radius seat, shank, cone-shank).

2 For nut installations install one new fastener onto the front and rear wheel by hand. Tighten fasteners to the recommended torque specification.

3 Remove both fasteners. Look at the seating surface of the fasteners. If the seating surface is not marked by the wheel, the lug nut may have bottomed out on the wheel stud. This means the lug nuts are not the proper ones for your vehicle.

4 If installing bolts, make sure the shank length matches your current lug bolt. Too short a length could cause thread damage. Too long a length can extend beyond the rotor and cause damage to other vehicle parts.


1 If studs are rusty, clean with a wire brush prior to installing lug nuts/bolts. Do not lubricate threads.

2 Start fasteners by hand.

3 Minimum thread engagement must be equal to the thread diameter of the wheel stud/bolt, if there are any questions regarding this call Technical Support at 1-800-444-5847.

4 Tighten fasteners in a progressive crisscross pattern to the recommended installation torque found in your vehicle owner’s manual. For best results, use a torque wrench and socket for final tightening. Fasteners should be retorqued after 25 miles of driving.

5 It is not recommended to use an impact wrench. Use of an impact wrench can result in uneven or over tightening of fasteners, which could damage wheels or distort brake rotors.

SplineDrive Tips:

1 SplineDrive lug nuts are for use on alloy wheels only, not for use on steel wheels.

2 Care must be taken not to dent or scratch SplineDrive lugs with colored caps or rings.

3 When removing the lug nut, do not drop. Carefully place down with aluminum cap up.

4 To install SplineDrive® Lug Nuts you will need to use the installation tool that came with the lug nuts. Insert tool carefully and apply inward pressure when tightening and loosening to keep the tool in place. (see figure 3*).

Helpful Hint:

Be sure to save enough Original Equipment Manufacturer fasteners for use with the O.E.M. spare tire/wheel.
