Summary for qq-n-290 class 1 Discussion
Military specification qq-n-290 class 1 is the focus of Henry’s question about the requirement for a screw under the old federal spec FED-QQN-290, now replaced by AMSQQN290. The only answer in the thread, from A., does not explain the class 1 requirement itself; instead, it directs Henry to obtain the official document by visiting astimage.daps.dla.mil/quicksearch/ and entering the specification number in the document ID box. The response implies that the authoritative source for the requirement is the specification text itself, rather than a summary in the thread. No alternate interpretations or conflicting views are offered, and no technical details about class 1 are provided beyond the document reference and replacement designation.
Please let me know the requirement of Military Specification
FED-QQN-290 (replaced by AMSQQN290)
Class 1 for screw.
Thanks,

A. Hello Henry!
To get a copy of any US military or federal specification, such as QQ-N-290, go to: astimage.daps.dla.mil/quicksearch/ and type the appropriate number in the document ID box.
Good luck!

A. QQ-N-290 is the US Federal Specification for electrodeposited nickel. Class 1 is for corrosion protection but you will need to read the entire specification to understand the requirements.
