How to find the right Solid Rivets AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Solid Rivets
- Specification and head type
- For aircraft work, use rivets to the MS20470 or AN470 universal-head spec or the MS20426 or AN426 100-degree countersunk spec, as the repair data calls for. Structural repairs must use the rivet the approved data specifies, not a look-alike.
- Alloy code
- AD (2117-T4) is the common field rivet; DD (2024-T4) 'icebox' rivets must be kept refrigerated or re-heat-treated before driving; A (1100) is for non-structural work. Using the wrong alloy gives the wrong strength, or cracks the head while driving.
- Shank length
- Shank protrusion beyond the material should be about 1.5 times the rivet diameter, giving a shop head about 1.5 times the diameter wide and 0.5 times the diameter tall. Correct protrusion produces a properly formed shop head without clinching or splitting.
- Edge distance and pitch
- Keep at least 2 times the rivet diameter from the edge and at least 3 times the diameter between rivets. Closer spacing tears the sheet or weakens the joint.
What to avoid
- Unspecified 'aluminum rivets' for aircraft work, which have no traceable spec or alloy marking.
- DD rivets that have warmed up, since they will crack when driven.
Questions
Can I set solid rivets without a rivet gun?
Small soft rivets can be set with a hand rivet set and hammer or a squeezer, but structural rivets need a rivet gun or squeezer and a bucking bar for consistent shop heads.
