What Is an MS21250 Bolt?

The MS21250 series is a high-strength, close-tolerance, shear-head bolt conforming to U.S. military specifications. These bolts are typically used in high-load structural applications across aerospace, defense, and rotorcraft assemblies.

Key Characteristics:

  • Material: Alloy steel or corrosion-resistant stainless steel

  • Thread: UNJF, rolled threads for enhanced fatigue resistance

  • Head Style: Flush shear head (100° countersunk), ideal for aerodynamic surfaces

  • Standards: Superseded by NASM21250, but still commonly referred to by its legacy MS number

  • Documentation: Full traceability, Manufacturer’s Certificate of Conformance (COC), Test Reports, and optional FAIR (First Article Inspection Report)

Applications

  • Fixed-wing military aircraft

  • Helicopters and rotorcraft
