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 aviation, especially those 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. Our range of UNF nuts covers most engineering applications. We also offer UNF threaded bar, hex bolts, hex setscrews and socket cap screws.
