Angle · AISC Shapes Database v15.0 · United States
L3X2X1/4 is a single angle with 76 × 51 mm legs, 6.4 mm thick, weighing 6.1 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
Single angles serve as braces, cleats and connection material. An angle bends about tilted principal axes, so the derived principal values below carry their angle.

Derived section properties
Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For L3X2X1/4 the computed area is 0.20% from published and Ix 0.26%. Where a value is also published, the published one above is the one to quote.
| Property | Value |

| Elastic modulus, Sx | 8,879 mm³ |
| Elastic modulus, Sy | 4,262 mm³ |
| Plastic modulus, Zx | 15,939 mm³ |
| Plastic modulus, Zy | 7,676 mm³ |
| Radius of gyration, rx | 24.3 mm |
| Radius of gyration, ry | 14.6 mm |
| Principal maximum, Imax (derived) | 522,172 mm⁴ |

| Principal axis angle, θp | 23.8° |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
