RE: What are Jack Screws
Each flange shail have a machine bolt mounted in a hole drilled on the flange center line at 90 deg. from the pressure taps, for use as a jack screw. Machine bolt shall be regular with one heavy hex nut.
A slot shall be provided in the flange 0.06 in. wider than the width across flats of the nut. The depth of the slot shall admit the nut so that there is no interference with the joining of the flanges when bolted together without orifice plate.
