Miscellaneous Beam · AISC Shapes Database v15.0 · United States
M8X6.2 is a miscellaneous light beam 203.2 mm deep with a 57.9 mm wide flange, weighing 9.2 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
M-shapes are light I-sections that fall outside the W series — small beams for light framing.

Derived section properties
Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For M8X6.2 the computed area agrees with the published value to 0.01% and Ix to 0.43%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 71,790 mm³ |
| Elastic modulus, Sy | 5,054 mm³ |
| Plastic modulus, Zx | 84,231 mm³ |
| Plastic modulus, Zy | 8,109 mm³ |
| Radius of gyration, rx | 78.8 mm |
| Radius of gyration, ry | 11.2 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
