Diameter Ratio = OD/1D Diameter Ratio = 2-3 Thickness = 1/2 to 2/3 Nominal Height = (Pull Out and Reassembly Needs) Gusset Height = 2/3 Height Taper = 1"/Side

Diameter Ratio =	Outside Diameter
	Inside Diameter

Critical Constraints

• Diameter Ratio: 2–3
• Thickness: 1/2 to 2/3 Nominal Wall Thickness
• Height: To suit pullout and reassembly requirements
• Gusset Height: 2/3 height
• Taper: 1" per side

Notes:

• Diameter Ratio: Minimum ratio of 2 reduces risk of boss failure due to hoop stress
• Thickness: Excessive thickness promotes sinkmarks
• Height:
  Use short boss if:
  A.) One time assembly
  B.) Low pullout force needed
  
  Use tall boss if:
  A.) Multiple assembly/disassembly required
  B.) Relatively large pullout force needed
  
  Tall boss provides more threads for reassembly engagement and increases pullout strength
  
  
• Gusset Height: Distributes applied stress over a larger area
