THREAD PITCH

Thread pitch refers to the steepness of the angle of thread, which is measured in threads per inch. Thread Pitch Chart shows the unified screwed thread for coarse and fine thread, as well as the thread pitch for stud bolts. Stud Bolt covered under the A193 or A320 ASTM Specifications utilize 8UN for all diameters 1" and above, meaning there are 8 threads per inch for these sizes. All other materials should be specified by the purchaser unless noted in the ASTM spec given.

LENGTH

Length can be measured one of two ways, either overall length (OAL) or first useable thread to first useable thread (FTF). Industry standard and stock is measured OAL. To find FTF measurement from OAL, simply subtract a quarter of an inch.

COATING AND PLATING STUD BOLTS

Stud bolts are most commonly available with a plain finish, which is also referred to as Black. However, there are also numerous applications that call for coating/plating, with the most common Teflon Blue coating. Teflon, or Xylan, coating provides for increased corrosive resistance, which is favorable that require increased corrosion resistance as well as the strength of B7 material.
