Driving 2017 rivets
2017-T3, 2017-T31 and 2024-T4 rivets are used in aluminum structures where more strength than 2117-T4 is needed (AC par. 7-2b).
2017 rivets above 3/16 in diameter must be kept packed in dry ice or refrigerated in the quenched condition until driven, or reheat-treated just before driving, or they are too hard to drive (AC par. 4-57).

Specifications as listed by MIL-HDBK-5J. Federal QQ-A specifications passed to SAE as AMS-QQ-A. Check the current revision.
Questions people actually ask
D rivet or AD rivet?
Use what the drawing or SRM calls for. D is stronger in shear, AD is driven as received. See the rivet alloy calculator.
Limits — when NOT to use this
- Not a source of design allowables. Values are for reference. MMPDS and the SRM govern a repair.
- Not a substitution approval. A different alloy or temper needs approved data.
