Sheet Metal Two Flanges Overlap Clearance Width Design

Flange Width (FM) = EM + RS + C/2 + EMT + SB

Where:

FM = Flange Width (in, mm),
EMT = Edge Margin Tolerance: Typical (.05 in, 1.27 mm),
C = Fastener Head Diameter (in, mm),
RS = Fastener Spacing (in, mm),
SB = Setback Radius on Outside Wall (in, mm),
EM = Flange Edge to Fastener Center (in, mm)
