Take no risks with your wheel assembly safety. This high-resistance wheel nut is specifically designed for wheels featuring a flat seat mounting hole. With a 12x125 thread pitch, it ensures optimal and consistent clamping force, which is essential for performance vehicles putting heavy stress on their running gear. Sold individually, this premium quality nut prevents thread stripping and guarantees perfect wheel centering on the hub.
Using incorrect hardware is one of the most critical mistakes in mechanics. By failing to replace worn nuts or using a tapered seat on a wheel designed for a flat seat, you risk loss of torque, destructive vibrations, or even stud shearing. Not having this 12x125 flat seat nut means compromising the safety of your sports vehicle and risking irreparable damage to your valuable wheels.
This model is the essential standard for many Japanese and European sports cars equipped with specific wheels. The flat seat allows for clamping force distribution over a wider surface, preventing damage to the wheel's metal. Manufactured from high-quality treated steel, this wheel accessory withstands the intense heat cycles generated by performance braking on the track or during spirited driving.
The mounting hole of your wheel must be perfectly perpendicular to the stud. If you install a tapered nut in a flat hole, the contact surface is insufficient, which inevitably leads to loosening. This is a crucial check-point when customizing your car with new wheels.
Absolutely not. For drivetrain balance and safety, each wheel must be secured with identical nuts. Mixing them could create unbalance and abnormal mechanical stress on the wheel hub.
