Notes
Dimensions are in millimeters unless otherwise indicated.
The length of the Stud Bolt does not include the height of the chamfers (points).
The length of the Stud Bolts includes one Spiral Wound Gasket with a 4.5mm thick sealing element, which is compressed to 3mm while tightening the Raised Face flange connection.
ID = Depending on the wall thickness of the pipe, must be specified by the purchaser.

Dimensional Tolerances of Slip On Flanges ASME B16.5
Outside Diameter *
Tolerances not listed in ASME B16.5 2013
≤ 24 = 1.6 mm
> 24 = ± 3.2 mm
Inside Diameter
≤ 10 = ± 0.8 mm
≥ 12 = + 1.6 mm / - 0 mm
Outside Diameter of Hub
≤ 12 = + 2.4 mm / - 1.6 mm
≥ 14 = ± 3.2 mm
Diameter of Counterbore
Same as Inside Diameter
Drilling
Bolt Circle = 1.6 mm
Bolt Hole Spacing = ± 0.8 mm
Eccentricity of Bolt Circle
≤ 2.1/2 = 0.8 mm max
≥ 3 = 1.6 mm max
Thickness
≤ 18 = + 3.2 mm / - 0
≥ 20 = + 4.8 mm / - 0
Length thru Hub
≤ 18 = + 3.2 mm / - 0.8 mm
≥ 20 = + 4.8 mm / - 1.6 mm
Diameter of Contact Face
1.6 mm Raised Face = ± 0.8 mm
6.35 mm Raised Face
Tongue & Groove / Male-Female
± 0.4 mm
Studs are measured parallel to the axis (L) from the first to the thread without the chamfers (points). S = free threads equals 1/3 time bolt dia
Hex bolts are measured from under the head to the end of the bolt
