L8×4×7/8 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.
L8×4×7/8 has a 8 in. long leg and a 4 in. short leg, 7/8 in. thick.
At 33.1 lb per foot it is one 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 = 12.5 in³ and its moment of inertia Ix = 62.6 in⁴, with a plastic modulus Zx = 21.7 in³.
