HSS4×4×3/16 square/rectangular HSS tube

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.

HSS4×4×3/16 is a square tube 4 in. by 4 in. with a 3/16 in. nominal wall.

At 9.42 lb per foot it is one of the 6 HSS4×4 sizes, which run from 6.46 to 21.63 lb/ft.

For strong-axis bending its section modulus is Sx = 3.1 in³ and its moment of inertia Ix = 6.21 in⁴, with a plastic modulus Zx = 3.67 in³.
