L6×4×5/8 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.
L6×4×5/8 has a 6 in. long leg and a 4 in. short leg, 5/8 in. thick.
At 20 lb per foot it is one of the 8 L6×4 sizes, which run from 10.3 to 27.2 lb/ft.
For strong-axis bending its section modulus is Sx = 5.29 in³ and its moment of inertia Ix = 21 in⁴, with a plastic modulus Zx = 9.44 in³.
