Bolts and Screws, Steel, Low Alloy Heat Treated, Roll Threaded
This procurement specification covers aircraft quality bolts and screws made from a low alloy steel of the type identified under the Unified Numbering System as UNS G87400, and of a series of room temperature tensile strengths ranging from 125 000 to 185 000 psi.
Revise sampling values for destructive tests to be in accordance with current practice on similar bolt specifications and clarify requirements for cold working fillet radii.
