Dimensions Slip On Flanges & Stud Bolts ASME B16.5

OTHER DIAMETERS

NPS 16 - I.D. 410.5

Notes..

Dimensions are in millimeters unless otherwise indicated.
The length of the Stud Bolt does not include the height of the chamfers (points).

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 top of de bolt
