Sheet Metal Two Flanges Overlap Clearance Width Design

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

or

Flange Width (FM) = SB + PT + S / 2 + EM

** Whichever is largest **

Where:

FM = Flange Width (in, mm),
EMT = Edge Margin Tolerance: Typical (.05 in, 1.27 mm),
C = Fastener Head Diameter (in, mm),
SB = Setback Radius on Outside Wall (in, mm),
PT = Tolerance of Part Radius (in, mm),
S = Outside Diameter of Ratchet Socket (in, mm),
EM = Flange Edge to Fastener Center (in, mm)
