  • Automotive brake & clutch systems

  • Hydraulic equipment

  • Fuel & lubrication systems

  • Aerospace and heavy machinery

  • Because they deal with high-pressure applications, even the smallest defect in a Banjo Bolt can result in leakage, pressure failure, or safety risks.


    Why is Manufacturing Banjo Bolts Challenging?

    Unlike standard fasteners, Banjo Bolts require precision engineering. Key challenges include:

    • Complex geometry – hollow bore, radial oil holes, and threading.

    • Tight tolerances – threads must meet metric or UNF standards.

    • Hard materials – typically alloy steel, stainless steel, or similar.

    • Consistency – mass production must maintain zero defects.

    Conventional CNC or manual machining often fails to balance accuracy, speed, and efficiency. That’s why Special Purpose Machines (SPMs) are the preferred choice for Banjo Bolt manufacturing.
