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...

Thefourthnumber is the designation which shows what the tolerances class is. Essentially the “size 1” screws have the most generous tolerance and are used for loose fits, while the “size 3” screws have the tightest fit. The A and B denote whether threads are “external” for a screw...

“internal” for a hole. In this case, a screw thread is an external thread, while a nut or tapped hole is always an internal thread. The important note is that the tolerance classes for holes or nuts should match the corresponding screw class. The takeaway message for this number is ...
