Other classes of fit include 4H, 5H, & 7H. Maximum rounded form minor diameter = d3max =  d2max - (0.5H + 2rmin (1 − cos Click here to return to the thread data chart page index. Disclaimer | Lower tolerance (ISO 1) generates a fine fit without a gap on the flanks between screw and nut. M=E+Const. The nut and bolt deviations and tolerance zones are illustrated here. Go and No-Go gages from OSG are ground premium HSS and hardened to 64Rc to ensure superior wear resistance. unless otherwise stated. Metric external thread dimensions are given in the external thread chart below according to ASME B1.13M standard. Thread pitch: The distance between two adjacent threads. Higher tolerance (ISO 3) generates a rough fit with a large gap. Using the principles of GO/NOGO gaging for internal threaded parts, a GO thread plug gage checks the minimum major diameter and minimum pitch diameter, and a NOGO thread plug gage checks that the maximum pitch diameter is not exceeded. 5H, 6H, 6G and 7H for internal threads, and 4H, 6g, 6e, 8g for external threads.. Generally 6H/6g are regarded as “medium fit”. Offering: List 15002 . Metric plug thread gages are used to inspect pitch diameter and pitch accuracy of internal threads. The designation of a screw thread gives the thread symbol, the nominal size, the pitch, and the thread tolerance class (Ex: M6 x 1 - 4g6g). 4H is a tight class of fit – comparable to a 3B . Type Of Gauge: Thread Plug Gauge. Unified Screw Thread series tables provide all this information. The common thread plug gauge's common precision is 6H! I know my description says electrical but there is no choice for optics engineer, which is my discipline.

The Minor diameter of the internal thread can be checked separately using a double ended plain plug gauge. Premium German made Metric Fine Right Hand Go Thread Ring Gauge. Note : ** 6H is normally selected for commercial internal (nut) threads. The external thread allowance may thus be used to accommodate the coating thickness on coated parts. btw, I have such a tool but is excel based and based on 2 different ways of. When the thread is inspected, it must be passed if the threading pass can be screwed through with the work piece thread, and the threading amount of the stop rule and the work piece thread is less than two thread pitches. There are two calculation options available, general engineering use or custom use. Thread pitch diameter, major diameter and minor diameter What is the difference between M6 X 1 6G and M6 x 1 6H thread gauges? he metric screw roduct tolerance or threads is the opposite of the inch design.

Between tolerances 6H (ISO2) and 6G (ISO3), and between 6G and 7G, there are also taps with tolerance 6HX and 6GX. General Note: All dimensions are in millimeters. ISO 965-1 tolerance practices. , Ryffel H.H., (2016) . Tolerance class can be selected among the alternatives 6e, 6f, 6g and 4h for bolts and 5H, 6H, 7H and 6G for nuts. Gages may be purchased individually or as assemblies. Thread Plug Gage Metric Size Class 6H. E=M-Const. For usage of the - Tolerance class for major diameter (M10 x 1 5g 6g), - Internal Screw Thread Designation: – Nominal Diameter x Pitch - Tolerance class for pitch diameter BS 3643 Pt1 and Pt2: 2007 specifies the fundamental deviations and tolerances for e.g. ISO metric BS3643/BS919 screw plug gauges are supplied as 6H as standard. Overview . In custom use, thread size, pitch and tolerance classes can be independently selected for custom metric thread dimensions calculations. For example: M12 x 1 - 6H/5g6g indicates a tolerance class of 6H for the nut (female) thread and a 5g tolerance class for the pitch diameter with a 6g tolerance class for the major diameter.
