  • The external thread has a special pitch diameter and minor diameter which installs into a MIL-S-8879 Class 3B, MIL-S-7742 Class 3B, or National Class 3 tapped hole.
  • Insert lengths shown are based on installation in 2024-T4 Aluminum and in such materials will accommodate tension loads up to the strength of a mating bolt heat treated to 145,000 PSI UTS. If this design criteria is required in parent materials of lower mechanical properties, longer insert lengths should be specified. Mating bolts have a thread engagement of 1.5 diameters or if insert has a thread lock, the bolt should extend through the insert 2 pitches including chamfer.
