L4×4×7/16 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.

L4×4×7/16 has equal 4 in. legs, 7/16 in. thick.

At 11.3 lb per foot it is one of the 7 L4×4 sizes, which run from 6.6 to 18.5 lb/ft.

For strong-axis bending its section modulus is Sx = 1.73 in³ and its moment of inertia Ix = 4.93 in⁴, with a plastic modulus Zx = 3.1 in³.
