| Thread Terminology |
| |
 |
A. FULL DIAMETER SHANK: Equal to major diameter of thread. Produced by cut thread or by roll thread on extruded blank. Characteristic of machine bolts and cap screws.
B. UNDERSIZED SHANK: Equal approximately to pitch diameter of thread. Produced by roll threading a non-extruded blank. Characteristic of machine screws. |
ROLLED THREAD: Threads are cold formed by squeezing the blank between reciprocating serrated dies. This acts to increase the major diameter of the thread over and above the diameter of unthreaded shank (if any), unless an extruded blank is used.
Classes of thread are distinguished from each other by the amounts of tolerance and allowance specified. External threads or bolts are designated with the suffix "A"; internal or nut threads with "B". |
| C. PITCH: The distance from a point on the screw thread to a corresponding point on the next thread measured parallel to the axis. |
CLASSES 1A and 1B: For work of rough commercial quality where loose fit for spin-on-assembly is desirable. |
| D. PITCH DIAMETER: The simple, effective diameter of screw thread. Approximately half way between the major and minor diameters. |
CLASSES 2A and 2B: The recognized standard for normal production of the great bulk of commercial bolts, nuts and screws. |
| E. MAJOR DIAMETER: The largest diameter of a screw thread. |
CLASSES 3A and 3B: Used where a closed fit between mating parts for high quality work is required. |
| F. MINOR DIAMETER: The smallest diameter of a screw thread. |
CLASS 4: A theoretical rather than practical class, now obsolete. |
LEAD: The distance a screw thread advances axially in one turn.
CUT THREAD: Threads are cut or chased; the unthreaded portion of shank will be equal to major diameter of thread. |
CLASS 5: For a wrench fit. Used principally for studs and their mating tapped holes. A force fit requiring the application of high torque for semi-permanent assembly. | | | |

| Types of Studs |
| |
 |
 |
| Type 1 |
Type 2 |
| Continuous-thread studs are threaded from end to end and are often used for flange bolting with two nuts applied. |
| Type 1 - General purpose. The length of this type is measured from end to end. Threads are UNRC-2A. |
Type 2 - Studs for temperature-pressure piping. These studs are made to the dimensional standard requirements of ANS B16.5 and have a length measurement requirement different from all other studs, i.e., the length is measured from first thread to first thread, exclusive points. Points are flat and chamfered. Threads are UNRC-2A for all sizes 1 in. and under and 8UNR-2A for all sizes over 1 in. |
| Tap-end Studs |
Double-end Studs |
 |
 |
Tap-end studs have a short thread on one end, called the tap end which is threaded to a Class NC5 or Class UNRC-3A fit. This end is for screwing into a tapped hole. The other or nut end is threaded with a Class UNRC-2A fit. Length of the stud is measured overall. The tap end has a chamfered point, but the nut end may have either a chamfered or round point, at the manufacturer's option. Tap-end studs are available in four types, as follows:
Type 1 - Unfinished, have a full diameter but no standard body tolerances.
Type 2 - Finished, having either an undersized body with rolled threads or a full-size body with cut threads, at the manufacturer's option. The body portion will be finished to a maximum Class 2A pitch diameter or maximum basic major diameter of the nut-end thread.
Type 3 - Finished, full-body, having tolerances equal to that on major diameter of Class 2A threads.
Type 4 - Finished close-body, milled or ground to tolerances specified by the user. |
Double-end studs have equal-length threads on each end to accommodate a nut and are threaded to a Class 2A fit. Length of stud is measured overall. Both ends have chamfered points, but round points may be furnished on either or both ends at the manufacturer's option, This style is furnished in the same four types listed for tap-end studs. Double-end studs are used for flange bolting or other applications where torching from both ends is necessary or desirable.
Most steel grades not heat treated or quenched and tempered can be furnished on special order for production quantities. Only the Type 2 continuous thread studs made to specification ASTM A193 grade B7 are stocked in a full range of sizes. | | |
