Disc Bolts, Nuts and Washers

AP Racing have changed the Cap headed bolts historically used for mounting discs to bells to a 6-Lobe bolt (pictured opposite) with an improved low friction coating.

  • The change over process is nearing completion and virtually all of our related products are now being delivered with the new 6-Lobe bolt.

     

    The 6-Lobe bolt offers the following advantages over a cap head:-

    - More consistent clamping loads.

    - Lighter.

    - Better corrosion resistance

    - Less prone to damage.

    - Improved airflow.

     

    The Cap Head bolt will continue to be available as a loose part in kits of 100.
