Steel Fasteners
I need qualified aerospace fasteners in this alloy. Who actually makes them, and are they on the approved source list?
What it is
Bolts, screws, nuts, rivets, pins and collars made to aerospace or military specification. A distinct manufacturing discipline rather than a mill product: qualification is per part number, and the approved source list is controlled by the airframer or prime.
- Typical dimensions
- Fractional through roughly 1 inch diameter for most airframe fasteners.
- Also known as
- bolts, screws, nuts, rivets, pins, collars, aerospace fasteners
Suppliers
Grouped by what they actually are. A mill and a distributor answer different needs.
Mills and producers 3
Companies that manufacture this form. Mill direct means longer lead times and mill minimums, with full melt traceability.
