Stud Bolts are externally threaded fasteners without a head, used with 2 nuts on either side, to replace a usual bolt and nut assembly. Stud Bolts can be manufactured and supplied in metric and inch sizes with variety of screw threads, including ISO Metric, UNC, UNF, UN and ACME. We produce stud bolts in many different materials including carbon steel, stainless steel, brass and alloys etc. ANSI, ASME, DIN, ISO, BS & IS standards specify many dimensional standards for stud bolts, among which ANSI/ASME B16.5, DIN 976, DIN 2510 are the most common ones. Depending upon their design and threading patterns, there are different types of stud bolts as below.
Continuous Threaded Stud Bolts (Fully Threaded Studs without Chamfered Ends)
Stud Bolts with uniform threads over the length are termed as continuous thread stud bolts. This type usually does not carry a chamfered end.
Tap End Stud Bolts
Stud bolts with unequal length of threads at extreme ends with non-threaded center.
Double End Stud Bolts
Stud bolts with equal thread lengths at either end with non-threaded center.
Double End Stud Bolts with Reduced Shank
Stud bolts with equal thread lengths at either end with center reduced further than the actual diameter of the stud
Flange Stud Bolts (Fully Threaded Studs with Chamfered Ends)
This type stands exclusive for studs bolts used in flange connection with continuous thread over the length and chamfered ends. The theoretical length is measured from its first to last thread unlike regular Continuous Thread Stud Bolts.
Welding Studs
Unlike others, these are welding studs used with nut on one side and welded to the support on the other. They are primarily manufactured as per DIN 525.
