Jackscrews for ASME B16.5 and ASME B16.47 Series A flanges.
Bolt dimensions are in metric units. i.e. Bolt dia x Bolt length.
Jacscrews are fully threaded UNC to ASME B1.1 class 2A and dimensions conform to ASME B18.2.1.
Jackscrews holes are normally threaded in the field. Two holes are provided on a flange assembly.
Where threading in field is expensive, the flanges can be purchased with predrilled holes.
