Full Threaded Studs

Full threaded stud bolts are also known as threaded rods. They have the threads along the length of their body. Fully threaded body helps it to fix from either end by nuts.

Full thread studs are made by cutting all thread rod to length or roll-threading pitch diameter cut blanks. One important consideration in ordering full useable thread studs is specifying the length. There are two standards. One is measuring the overall length of the part (this is how we typically supply our studs full-form). The other is measuring from the first full-form useable thread on one end to the first full thread on the other. As studs are generally chamfered on both ends, the first-to-first measurement will be 1 to 2 pitches less than the overall. First-to-first measurements are usually specified in high temperature and high pressure applications, particularly where ASTM A193 is specified.
Nickel Systems stocks all thread rod in Hastelloy® C276 (Alloy C276), Carpenter® 20 (Alloy 20), Duplex 2205, 316 Stainless and 18-8 Stainless, which can be cut to length and shipped in short order. We can also supply studs to A193 specs (B8, B8C, B8M, B8R, B8S, B8T), Monel® (Alloy 400, Alloy 500), AL6XN®, Nitronic® (50 and 60) and other non ferrous materials.
