Kobout – Your Specialist in Imperial Fasteners
What Are UNC and UNF Threads?
UNC (Unified National Coarse) and UNF (Unified National Fine) are thread types defined by the Unified Thread Standard (UTS). Unlike metric threads (such as M6 or M10), these imperial threads are measured in inches.
UNC has a coarse pitch with fewer threads per inch, making it ideal for use in softer materials or where fast assembly is required.
UNF has a fine pitch with more threads per inch, providing a stronger hold in harder materials and greater resistance to vibration.
These thread types are widely used in machine construction, automotive applications, agricultural machinery, and American-built equipment.
