Type:

This specification covers metric bolts and screws made from a low alloy steel of the type identified under the Unified Numbering System as UNS G87400. The following specification designations and their properties are covered:

MA3376 860 MPa minimum ultimate tensile strength at room temperature

MA3376-1 1000 MPa minimum ultimate tensile strength at room temperature

MA3376-2 860 MPa minimum ultimate tensile strength at room temperature

516 MPa minimum ultimate shear strength at room temperature

MA3376-3 1000 MPa minimum ultimate tensile strength at room temperature

600 MPa minimum ultimate shear strength at room temperature

Application:

Primarily for joining parts where minimum tensile strengths of 860 MPa and 1000 MPa are required. Also, for joining parts where minimum shear strength of 516 MPa and 600 MPa are required.
