Not sure what thread you need?
British Standard – The British Standard form is based on a 55° thread angle with its pitch being measured in thread per inch (TPI). The British Standard comes in different standards, including fine pitch series British Standard Fine (BSF) and coarse pitch series British Standard Whitworth (BSW), named after its developer Sir Joseph Whitworth.
Unified Thread Form – This thread system is known today as the unified thread system and is based on a thread angle of 60° with its pitch being measured in thread per inch (TPI). The Unified Thread Form comes in different standards, including fine pitch series Unified National Fine (UNF) and coarse pitch series Unified National Coarse (UNC).
Coarse Vs Fine Thread – The suitability of a coarse or fine thread for a particular application has to be determined on a case-by-case basis. In general, both coarse and fine threads are capable of providing sufficient strength for most applications. Coarse threads are easier to assemble and need less care; hence they are more commonly used. Fine threads will, in general, have higher load carrying capacities and higher resistance to vibration loosening. Fine threads are less tolerant to damage and are easily cross-threaded and therefore require careful assembly. Coarse thread forms are commonly used in applications where cross threading may be in issue since coarse threads are harder to cross thread.
