Bolts and Screws, Steel, Low Alloy Heat Treated, Roll Threaded
AS7452B
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.
Rationale: 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.
