Stud Bolts, a term used for cut-to-length all thread rod, are used for: bolting together flanges, anchor bolting, as well as general fastening.
Bangdong is a Stud Bolt distributor, offering stud bolts in carbon, stainless, along with several special alloys. With stud bolt diameters ranging from 1/2" to 4", Bangdong can provide the stud bolts required for virturally any project.
Bangdong Supply stocks Grade B7 Stud from 1/2" - 2" diameter in: Plain (black) finish, Teflon Blue, and Cad Plating. Bangdong also stocks B8 and B8M stud bolts from ¼ - 1-1/2". we can also provide larger stud bolts, stud bolts made from different materials (B8, B8M, Alloy 20, Monel, Hastelloy, Inconel, Titanium, etc), as well as different coatings. While many of the larger diameter items can be made available for a next-day delivery, some of the special alloys and coatings may be subject to a longer lead time.

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 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.
Stud bolts can be made from many different grades of material, but the most common materials are listed below. The A193 and A320 pages provide the chemical and mechanical properties of these material grades below.
A193 B7 – This is the most common grade for which stud bolts are produced. B7 is a Chrome-moly, Alloy steel that is made to AISI 4140/4142, and it is quenched and tempered.
A193 B7M – The [M" here stands for Modified (heat treated) B7 material
A193 B16 - Chrome-moly-vanadium, Alloy steel, AISI 4140/4142 quenched and tempered
A320 L7 - AISI 4140/4142 quenched and tempered Alloy steel
A320 L43 - AISI 4340 quenched and tempered Alloy Steel
A193 B6 – Heat treated 410 stainless (410HT)
A193 B8 – Produced to grade AISI 304, carbide solution treated, standardly available in class 1
A193 B8M – Produced to grade AISI 316, carbide solution treated, standardly available in class 1
A193 B8C- Grade 347 stainless material
A193 B8T – Grade 321 stainless material
A320 B8 - Produced to grade AISI 304, carbide solution treated, standardly available in class 1
A320 B8M - Produced to grade AISI 316, carbide solution treated, standardly available in class 1

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.
