FASTENER KIT, UNF / 160PCS

KAP013 135.629 pièces détachées

High Performance Fastener kit (UNF). UNF washers, screws and bolts. Different sizes. UNF thread bolts and screws conform to the Unified National Fine (UNF) thread standard, distinguishing themselves by their finer pitch compared to the Unified National Coarse (UNC) threads. This finer pitch translates to a greater number of threads per inch, resulting in a snugger and more precise fit when engaging with a corresponding part. Identified by specifying the nominal diameter followed by the number of threads per inch, UNF threads, such as a 1/4-inch diameter bolt with 28 threads per inch denoted as 1/4-28 UNF, boast a finer pitch than their UNC counterparts. This finer pitch enhances the number of engaged threads, thereby fortifying the connection. UNF thread bolts find widespread use in industries necessitating heightened thread engagement and strength, such as automotive, aerospace, machinery, and precision equipment. Thanks to their increased thread engagement, UNF thread bolts and screws exhibit superior load-bearing capacity compared to UNC thread bolts of equivalent size. Consequently, they are better suited for applications demanding elevated tensile strength and resistance to vibration.
