These specialized fasteners secure wheels to vehicles. Instead of the more common hexagonal or lug configuration, they employ a splined interface. This design features ridges and grooves on both the nut and the wheel stud, ensuring a precise and secure fit. A dedicated socket with matching splines is required for installation and removal.
The unique interface offers several advantages. It provides a larger contact area, distributing torque more evenly and reducing the risk of rounding or stripping. This is particularly beneficial in high-torque applications, such as motorsport or heavy-duty vehicles. Additionally, the design deters theft, as standard tools are ineffective. The emergence of this technology arose from the need for more robust and tamper-resistant wheel fastening systems, improving both safety and performance.
