2L4×4×5/8×3/8 double 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.

2L4×4×5/8×3/8 has equal 4 in. legs, 5/8 in. thick, spaced 3/8 in. back to back.

At 31.4 lb per foot it is one of the 21 2L4×4 sizes, which run from 13.2 to 37 lb/ft.

For strong-axis bending its section modulus is Sx = 4.76 in³ and its moment of inertia Ix = 13.2 in⁴, with a plastic modulus Zx = 8.56 in³.
