2L6×6×9/16×3/8 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.

2L6×6×9/16×3/8 has equal 6 in. legs, 9/16 in. thick, spaced 3/8 in. back to back.

At 43.8 lb per foot it is one of the 27 2L6×6 sizes, which run from 24.8 to 74.8 lb/ft.

For strong-axis bending its section modulus is Sx = 10.2 in³ and its moment of inertia Ix = 44 in⁴, with a plastic modulus Zx = 18.4 in³.
