Angle · AISC Shapes Database v15.0 · United States
L3X2-1/2X1/2 is a single angle with 76 × 64 mm legs, 12.7 mm thick, weighing 12.7 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 L3X2-1/2X1/2 the computed area is better than 0.01% from published and Ix 0.16%. Where a value is also published, the published one above is the one to quote.

| Elastic modulus, Sx | 17,070 mm³ |
| Elastic modulus, Sy | 12,193 mm³ |
| Plastic modulus, Zx | 40,968 mm³ |
