L4×4×5/8 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.

L4×4×5/8 has equal 4 in. legs, 5/8 in. thick.

At 15.7 lb per foot it is one of the 7 L4×4 sizes, which run from 6.6 to 18.5 lb/ft.

For strong-axis bending its section modulus is Sx = 2.38 in³ and its moment of inertia Ix = 6.62 in⁴, with a plastic modulus Zx = 4.28 in³.
