Every metric bolt is assigned a class number in terms of megapascals (MPa). For standard-size bolts, the thread pitch is either fine or coarse. (Nominal diameter is more of a label than a size. Choose from our selection of metric U-bolts, including over 850 products in a wide range o...
Thread Pitch ChartThread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter. Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts. Coarse thread is benefic...
How to Determine Bolt Thread Size Lastly, threads on both metric and UTS fasteners are also categorized as coarse, fine or extra-fine. UTS thread types are typically labelled UNC (Unified Coarse), UNF (Unified Fine) or (Unified Extra Fine (UNEF). There is no difference in manufacturing qual...
