Angle · AISC Shapes Database v15.0 · United States
L8X8X7/8 is a single angle with 203 × 203 mm legs, 22.2 mm thick, weighing 67.4 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 L8X8X7/8 the computed area is 0.51% from published and Ix 0.17%. Where a value is also published, the published one above is the one to quote.
