c
Shape is slender for compression with Fy = 50 ksi.
g
The actual size, combination and orientation of fastener components should be compared with the geometry of the cross section
to ensure compatibility.
h
Flange thickness greater than 2 in. Special requirements may apply per AISC Specification Section A3.1c.
v
Shape does not meet the h /tw limit for shear in AISC Specification Section G2.1(a) with Fy = 50 ksi.

c
Shape is slender for compression with Fy = 50 ksi.
f
Shape exceeds compact limit for flexure with Fy = 50 ksi.
g
The actual size, combination and orientation of fastener components should be compared with the geometry of the cross section
to ensure compatibility.
h
Flange thickness greater than 2 in. Special requirements may apply per AISC Specification Section A3.1c.

c
Shape is slender for compression with Fy = 36 ksi.
f
Shape exceeds compact limit for flexure with Fy = 36 ksi.
g
The actual size, combination and orientation of fastener components should be compared with the geometry of
the cross section to ensure compatibility.
t
Shape has tapered flanges while other M-shapes have parallel flange surfaces.
v
Shape does not meet the h/tw limit for shear in AISC Specification Section G2.1(b)(i) with Fy = 36 ksi.
— Indicates flange is too narrow to establish a workable gage.

Shape is slender for compression with Fy = 36 ksi.
f
Shape exceeds compact limit for flexure with Fy = 36 ksi.
g
The actual size, combination and orientation of fastener components should be compared with the geometry of the
cross section to ensure compatibility.
t
This shape has tapered flanges while all other MT-shapes have parallel flange surfaces.
v
Shape does not meet the h/tw limit for shear in AISC Specification Section G2.1(a) with Fy = 36 ksi.
— Indicates flange is too narrow to establish a workable gage.
