L6×4×9/16 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.

L6×4×9/16 has a 6 in. long leg and a 4 in. short leg, 9/16 in. thick.

At 18.1 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 = 4.81 in³ and its moment of inertia Ix = 19.2 in⁴, with a plastic modulus Zx = 8.59 in³.
