The Wilwood 230-12121 Brake Rotor Hat Bolt Kit provides reliable hardware for securing a brake rotor to its rotor hat. Designed with a 5/16-18 thread and a 0.750-inch length, each bolt is suited for compatible Wilwood brake rotor and hat assemblies that require a Torx button-head fastener. The stainless steel construction offers durable corrosion resistance for dependable service in demanding brake system environments.

The Torx drive helps provide positive engagement during installation and removal, while the button-head profile maintains a clean, low-profile appearance around the rotor assembly.
