milled thread or rolled thread

  • PTP fastener capabilities include thread rolling milling

    Rolled threads are often specified due to their superior tensile shear and fatigue strength. Where competitive processes produce the threads by removing material thread rolling displaces the material using hardened steel dies. Dies typically have a Rockwell of 58-63 and dies are specific to each thread size and thread form.

    Savings of 75 of threading time are common when thread rolling replaces hobbing milling and die head threading. Even greater savings result when rolling replaces thread grinding and single point threading. Also rolled parts are more efficient and run cooler and quieter than cut-thread parts because of their superior surface finish.
