THREADED RODS & STUDS
ASTM A193 B7 Fully Threaded Stud Bolts
B7 fully threaded studs for specified flange and pressure-equipment bolting enquiries.

Product Overview
A fully threaded B7 stud provides a nut connection at both ends for assemblies that call for this bolting grade. The material specification and the finished stud dimensions perform different roles, so both must be stated in procurement documents. Length may be defined overall or between the first full threads, and that convention needs to be explicit.
For an accurate quotation, specify the thread size, nominal length, material requirement and surface finish, together with the intended mating component. Dimensions, inspection requirements and the exact material and finish combination must be agreed before order confirmation.

Size Range / Technical Notes
- Size Range
- Specify diameter, pitch or thread series, stud length convention and end preparation. Exact size and material combinations require confirmation.
- Technical Notes
- B7 is not B7M and is not a stainless grade. A193/A193M does not alone define the complete flange assembly or all stud dimensions. Confirm matched nuts, heat treatment, testing and traceability. No service-temperature or pressure rating is asserted.
