B7 Studs Product Summary

B7 studs are cut-to-length all-thread rod, and common applications include: bolting flanges together, anchor bolting, and general fastening.

The specifications for B7 studs are governed by ASTM A193, and the material used for B7 studs is a Chrome-moly alloy steel that is quenched and tempered.

The length for B7 studs can be measured using either: overall length (OAL) or first useable thread to first useable thread (FTF). Industry standard is now OAL, but to calculate FTF measurement from OAL, simply subtract a quarter of an inch.

The thread pitch (threads per inch) for B7 studs with diameters below 1” is governed by coarse fastener thread pitches.   For all diameters 1” and above, B7 studs use 8UN, which means there are 8 threads per inch for these sizes.

Dual certified b7 studs

B7 studs can be provided as “dual certified,” meaning they conform to both A193 B7 and also meet the requirements for A320 L7.
