L8×4×7/16 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.

L8×4×7/16 has a 8 in. long leg and a 4 in. short leg, 7/16 in. thick.

At 17.2 lb per foot it is the lightest of the 7 L8×4 sizes, which run from 17.2 to 37.4 lb/ft.

For strong-axis bending its section modulus is Sx = 6.59 in³ and its moment of inertia Ix = 34.2 in⁴, with a plastic modulus Zx = 11.6 in³.
