  • <4>Dimension "L" will be threaded its full lenght when it is "C" dash length or shorter. For nut end lenngth longer than "C" dash length with dimension "L" threaded its full length use "SFT" prefix (Example: SFT101-9SA10A). For nut end length see part number coding.
  • The stud end thread has a special pitch diameter and minor diameter which installs into a MIL-S-8879 class 3B, FED-STD-H28/2 class 3B, or National class 3 tapped hole.
  • Studs are installed in accordance with MS51995.
  • Stud end thread lengths shown are based on installation in 2024-T4 Aluminum and will accommodate tension loads up to the strength of the nut end. If this design criteria is required in parent materials of lower mechanical properties, longer stud end lengths than shown above in column "F" should be specified.
  • <8>2 max incomplete threads.
  • Mating lockring is not included with stud. It must be ordered separately.
