Miscellaneous Beam · AISC Shapes Database v15.0 · United States
M12X10 is a miscellaneous light beam 304.8 mm deep with a 82.6 mm wide flange, weighing 14.9 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 M12X10 the computed area agrees with the published value to 0.01% and Ix to 0.49%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 169,345 mm³ |
| Elastic modulus, Sy | 10,422 mm³ |
| Plastic modulus, Zx | 200,397 mm³ |
| Plastic modulus, Zy | 16,727 mm³ |
| Radius of gyration, rx | 116.5 mm |
| Radius of gyration, ry | 15.0 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
