*WARNING* The availability of unified fasteners is very limited. If the item you would like to purchase is out of stock, please contact us before placing a backorder. 

Range of Unified National Coarse (UNC) &  Unified National Fine (UNF) fasteners such as set screws, bolts & nuts. These threads have a higher number of threads per inch, resulting in a tighter and more precise fit when engaged with a mating part.

UNC threads are unified coarse-pitch threads. These are less likely to cross-thread allowing faster assembly and disassembly (Generally used in mass production). Large threads also allow for thicker plating and coatings. 

UNF threads have a finer pitch than UNC threads. This means there are more threads per inch, resulting in a greater number of engaged threads and a stronger connection.
