Stud Bolt

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.

C&N is offering stud bolts in carbon, stainless, along with several special alloys. With stud bolt diameters ranging from 1/2” to 4″.

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.
