Is anyone familiar with a product design called a hydraulic nut and what is your opinion on replacing the standard A194 nuts with this design. Does the hydraulic nut conform to any standards.

No, not a superbolt a "hydraulic nut". I've had my share of superbolts and each bolt is like tightening a complete flange and then when you get ready to disassemble them, all the little studs that hold it together have to be burn't or sawed off.

hello studbolter, there are no industry standards that govern the use of hydraulic nuts. Hydraulic nuts are being used to replace standard A194 nuts. They come in a variety of materials including 4340, a similar and slightly superior grade of steel to A194. Have a look at www.blackhawknuts.com
