UNF (Unified National Fine) thread is the fine pitch counterpart to UNC. The fine pitch has greater resistance to being loosened by vibration and the smaller lead angle allows for finer tension adjustment. As such, it is often specified in vehicles and aerospace, especially if manufactured in North America. UNF fasteners are sized in imperial units, similar to BSF fasteners, but the two are differentiated by the angle of the thread profile. Hexagon head fasteners are driven with a socket or spanner, which are both very effective torque transfer methods, so they are suitable for applications that require high clamping force. We also offer UNF hexagon full nuts, threaded bar, hex bolts and socket cap screws.
