L8×4×5/8 angle

Detailing dimensions and section properties from the AISC Shapes Database, 16th Edition. Values are shown to the nearest 1/16 in. as they appear on a shop drawing.

L8×4×5/8 has a 8 in. long leg and a 4 in. short leg, 5/8 in. thick.

At 24.2 lb per foot it is one of the 7 L8×4 sizes, which run from 17.2 to 37.4 lb/ft.

For strong-axis bending its section modulus is Sx = 9.2 in³ and its moment of inertia Ix = 47 in⁴, with a plastic modulus Zx = 16.1 in³.
