Pier Components specializes in manufacturing metric fasteners, parts, components, hardware kits, or assemblies for virtually any finished good. If you manufacture it, we can supply the components. If you want it manufactured, they can provide the entire assembly, packaged and ready for your customer. Metric fasteners are designated with the letter "M" followed by the major (or outside) diameter in millimeters (mm) of external threads, an "x", and the pitch of the threads. Bolts have external threads; nuts have internal threads. Thread pitch is the distance in mm between adjacent thread crests or adjacent thread roots. Threads are divided into coarse types (larger numbers) and fine types (smaller numbers). The "standard" or "preferred" thread is the coarse pitch. Fine pitches are used due to space or wall thickness considerations. Bolts are differentiated from screws in that a bolt is held in place using a nut; screws thread directly into the part being fastened.
