These thread sizes and classes represent bolts and screws, as well, as other It refers to the tightness or looseness of the thread fit, based on the manufacturing tolerances. If you want to name a fit between threaded parts, the designation is, for example: M 6 – 6H/6g. These thread sizes and classes represent bolts and screws, as well, as other The final acceptance of threads after coating should be determined by using 6H GO plug gages for internal threads and 6h GO ring gages for external threads. , D: min. All dimensions in mm unless otherwise stated. It guides the manufacturing of thread plug gages and helps in inspecting the threaded parts to ensure they meet the specified Mechanical Tolerance Chart Data. Threads produced to ASME B1. 5+0. It is used to accomodate plating, finishing and coating to a limited extent and threfore, has fair tolerance For coated threads, the tolerances apply to the parts before coating, unless otherwise stated. 更低的公差 (iso 1) 可使螺钉与螺帽之间在牙侧实现无间隙的精度配合。更高的公差 (iso 3) 可实现具有较大间隙的松配合。如果要为螺母涂覆涂层或更希望实现松配合，则可使用该公差。在公差6h (iso2) 与6g (iso3) 之间以及6g与7g之间，也提 ANSI Screw and Nut Threads Size Chart. The "6g" gauge has a looser tolerance, suitable for Sandvik Coromant The small diameter tolerance of internal thread 6H (based on the pitch) and the calculation of the small diameter value. The tolerance class 6H is the most common one you'll regularly come across. Related size for the tolerance classes 4H, 5H, 6H and 7H for internal threads (nuts) and 4h, 6g and 8g for external threads (bolts) where appropriate for: coarse pitch series within the range 1 mm The following table chart are standard metric internal thread sizes M 50 - M 72 per. I don't think 6HX is a valid specification for a threaded hole; it really refers to the tap used to make a 6H thread when rigid tapping.
