MS21042 self-locking nuts.
Identify the reduced-height, reduced-hex locking-nut family and distinguish it from other military nut references.
// IDENTIFICATION
A distinct locking-nut envelope
The series identifies MS21042 as a reduced-hexagon, reduced-height, ring-base self-locking nut family in non-corrosion-resistant steel, with a 450-degree-F designation. Check the governing issue for detailed material, finish and performance requirements.
// STANDARD STATUS
Document reference
The document status review identifies MS21042 as canceled and superseded by NASM21042. Use the original drawing callout and required revision when requesting a quote; do not infer a full replacement designation from the document name alone.
// RELATED SERIES
Compare locking-nut families
Reduced-height, regular-height and nonmetallic-insert nuts differ in envelope and locking construction. They should not be grouped as equivalent simply because they accept the same screw thread.
