Shoulder screws for the New Orleans, Louisiana service area feature three main sections: head, shoulder, and thread. The head has the largest diameter, the shoulder is described by its diameter and length, and the thread has a major diameter slightly smaller than the shoulder diameter. What makes these screws unique is the mechanical components the shoulders can accommodate. Bearings mounted on shoulders create simple cam followers.

    • 416 – stronger than 300 series steels
  • Alloy steel – the original steel used, common in commercial-grade screws
  • Mild steel – less expensive than stainless, good for light-duty applications
  • Brass – natural lubricity makes it good for sliding and rotating applications, good for light-duty
