Bolt Science Unified and Metric Thread Forms Information on Screw Threads In November 1948 the Unified thread was agreed upon by the UK, the US and Canada to be used as the single standard for all countries using inch units.
Common Terminology for Thread Rolling Cleveland, OH
Common Terminology for Thread Rolling. THREAD ROLLING IS SUPERIOR. Thread rolling is widely accepted as the fastest and prefered method of economically producing uniform smooth, precise threads of superior physical qualities. This process is also capable of performing non-threading operations such as burnishing, knurling and rolling of helical
Unified Fine (UNF) and Unified Coarse (UNC). American threads consist of two common and easily obtained thread patterns known as U. N.F and U.N.C. U.N.F [national fine] is exactly the same as the old S.A.E [standard american engineers] that existed before threads were unified.

Aug 28, 2017 · The UNS standard contain 3 thread classes 1A, 2A and 3A for external threads, 1B, 2B and 3B for internal threads, the higher the number the smaller the allowance. A 1A thread will always have a Max Major Diameter smaller then the nominal diameter.
Modern screw thread rolling whereby threads are formed completely by chipless cold forging first began in the late 1800s. Heavy thread rolling of Acme, Ball screw and worm thread forms began in the late 1950s. Because of its many advantages, thread rolling is the preferred method of manufacture today.
How to Determine Bolt Thread Size Bolt Threads Strength
UTS thread types are typically labelled UNC (Unified Coarse), UNF (Unified Fine) or (Unified Extra Fine (UNEF). There is no difference in manufacturing quality between coarse, fine and extra-fine thread types, but there are differences in how they are employed. Coarse threads are thicker and more durable than fine-threaded hardware.

Thread Rolling / Profile Rolling Using the process with two (2) Rolling Dies the workpiece is typically placed on a supporting blade. At least one (1) rolling slide has a feed movement to perform the forming process. Simultaneously the dies are rotating synchronously in contact with the workpiece, whereas the profile will be formed out.
