NOTES:UNLESS OTHERWISE SPECIFIED
[1] MATERIAL: 1117 steel per ASTM A108. NOTE: These parts are available in other materials. Refer to page
27.
2. HEAT TREAT: None.
3. FINISH: Cadmium plate per QQ-P-416, TY II,CL3.
[4] 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. Refer to page 55.
5. Inserts are installed and removed per page 28.
6. Insert lengths shown are based on installation in 2024-T4 Aluminum and in such materials will accommo- date
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 should
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.
[7] Mating lockring is not included with insert. It must be ordered separately.
