Frequently asked questions

Can LOKRON supply valve fasteners to a drawing?

Yes. Send the valve drawing, stud length, thread, nut grade, coating and quantity for a drawing-based quotation.

Which stud grade is common for industrial valves?

A193 B7 with A194 2H nuts is common for many pressure and process applications, but temperature, corrosion and code requirements determine the final grade.

Can valve fasteners be individually marked?

Project-specific marking and packing identification can be requested for traceability and assembly control.
