Important Wheel Compatibility Notice

These lug nuts are designed for aftermarket wheels that use a 60-degree tapered lug seat.

Do not use these lug nuts with factory OEM wheels unless the wheel manufacturer specifically confirms compatibility.

Many original-equipment wheels use a different lug-seat design, such as a ball seat, radius seat, mag/shank seat, or captive washer configuration. Using the wrong seat style can prevent proper clamping and may damage the wheel or wheel studs.

Thread Size Compatibility

The M12x1.50 thread pitch is commonly found on select:

• Honda
• Acura
• Toyota
• Lexus
• Mazda
• Mitsubishi
• Other vehicles using M12x1.50 wheel studs

Thread pitch alone does not confirm fitment. Verify both the vehicle's wheel-stud thread and the wheel's lug-seat design before ordering.

Open-End Design

The SR48 open-end design allows the wheel stud to extend through the lug nut instead of being limited by a closed end.

This makes the SR48 particularly useful for vehicles equipped with:

• Extended wheel studs
• Motorsport wheel studs
• Wheel spacers requiring additional stud engagement
• Track-oriented wheel setups

The open design can also make visual inspection of wheel-stud engagement easier.

Installation Note

Before installation, confirm:

• Vehicle uses M12x1.50 wheel studs
• Wheel uses a 60-degree tapered lug seat
• Lug nuts provide adequate thread engagement
• Extended studs do not interfere with surrounding components
• Lug-seat surfaces are clean and undamaged

Start each lug nut by hand to prevent cross-threading.

Tighten the lug nuts in the proper crisscross sequence using the vehicle or wheel manufacturer's specified torque. Do not use an impact gun for final tightening.

Recheck lug-nut torque after the initial driving period.
