With our extensive inventory of finished standard thread gages and fast deliveries for manufactured specials Swanson Tool Manufacturing can quickly service your needs Using Thread Gages 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 This standard was originally issued in 1969 and revised in 1975 The first revision was based on lSO R 1502 1970 ISO general purpose metric screw threads Gauges This revision has been taken up to harmonize with ISO 1502 1996 The text of ISO Standard has been approved as suitable for publication as Indian Standard without deviations BS standard Basic Dimensions B S 3643 Part I amp amp II – 2007 Gauging Practice B S 919 Part III – 2007 JIS standard Basic Dimensions JIS B 0209 Gauging Practice JIS B 0251 2008 Manufacturing Range Diameter 1 6 mm to 300mm amp Pitches covered are 0 35mm to 8 mm We also offer Special gauges as per the customers drawings amp amp requirements 2022 02 28 nbsp 0183 32 What are the best Bolt Thread Gauge products in 2022 We analyzed hundreds of Bolt Thread Gauge reviews to do the research for you Here are top 19 items Unified Inch standard gages are manufactured per ASME B1 2 M Series Metric thread gages are manufactured per ASME B1 16M Standard thread gages are made to a Class X tolerance Gages may be purchased individually or as assemblies Plug gage assemblies are marked with the thread size class of fit and pitch diameters Pipe Gages per ASME B1 20 1 ASME

Threaded Ring Gauges for NPT Pipe Threads with Calibration Certificate To ensure accuracy of NPT pipe thread measurements these gauges include a certificate of calibration traceable to NIST that states they ve passed a test for accuracy Threaded Ring Gauges for NPT Pipe Threads Measure NPT pipe threads Threads per Inch and Thread Pitch Size Checkers for gauges for testing the product thread The basis for determining the gauge limit is the magnitude of the product tolerance i e the larger the product tolerance the larger the gauge limit regardless of diameter The gauges recommended to be used are as follows For testing internal product threads a double ended screw plug gauge Style E may be used O NUT BOLT g g e 1 Thread plug gauge and thread ring gauge all packed with standard plastic tool box if you need customized boxes pls inform us in advance 2 the tool box packed with Pearl cotton then in carton box if for big heavry product we will packed with wooden box Certificate The customized thread gauge with the factory test data report if you need offical certification pls inform us in Standard Thread Rings Disks of heavy metal with a central threaded hole are made to match a particular OD thread The gage is screwed on the part Standard Pitch Diameter Chart 16 Plug Thread Gages NOMINAL SIZE UNIFIED PITCH DIAMETERS CL 2B CL 3B 0 80 UNF 0519 0542 0536 0002 0002 0 176 30 1 64 UNC 0629 0655 0648 0002 0002 0 176 30 1 72 UNF 0640 0665 0659 0002 0002 0 176 30 2 56 UNC 0744 0772 0765 0002 0002 0 176 30 2 64 UNF 0759 0786 0779 0002 0002 0 176 30
