We no longer have a manufacturing source for the forged bolt component of the NAS573 assemblies; however, we may have an alternate part that would be acceptable. We have manufactured a machined bolt in lieu of a forged bolt. All material callouts, dimensions and finishing processes are the same as NAS573-11 or NAS573-12 with the exception that this is a MACHINED bolt and we have also added the additional step of 100% non-destructive testing.
The MOD NAS573 (using the MACHINED bolt) assemblies are comprised of
- NAS573-7 or NAS573-8 NUT
- NAS573-9, NAS573-9P, NAS573-10, or NAS573-10P HINGE
- AP573-11 or AP573-12 MACHINED BOLT
- MS20392-1C15 PIN
- MS24665-151 COTTER PIN
- 10-32 or ¼-28 ALUMINUM ACORN NUT
