L4×3×5/8 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.

L4×3×5/8 has a 4 in. long leg and a 3 in. short leg, 5/8 in. thick.

At 13.6 lb per foot it is the heaviest of the 5 L4×3 sizes, which run from 5.8 to 13.6 lb/ft.

For strong-axis bending its section modulus is Sx = 2.28 in³ and its moment of inertia Ix = 6.01 in⁴, with a plastic modulus Zx = 4.08 in³.
