General Purpose Acme Thread Gauges

Are you wondering how to use an acme thread gauge? The process starts by selecting the appropriate product. Customers can choose from acme thread ring gauge options or thread plug gauges. Consider an acme thread ring gauge set to inspect external parts, while checking internal threads with plug gauges. Both provide “GO and NOT GO” capabilities. “GO” thread rings allow external threaded parts to enter and “NOT GO” thread rings don’t. Likewise, “GO” plug gauges enter threaded parts while “NOT GO” plug gauges do not enter.

General purpose acme thread gauges are broken down into three fit classes (2G, 3G and 4G).

ACME Thread Ring Gages: ACME Threads are used for translation motion in machine tools like lead screws where rapid movement is required or in screw jacks, where load to be shared is more. SOWANTGage provides a complete line of standard and special General Purpose ACME GO/NO GO Thread Ring Gages in compliance with ASME B1.5 - 1997. Acme Thread Ring Gages are used to gage an external threaded product. There are three classes of fit for ACME General Purpose thread gages; 2G, 3G and 4G.

       Sowant gage can produce the MOD acme thread ring gages per your thread data or thread prints , usually the delivery time 4 weeks with calibration report. MOD means modified thread, sometime pitch diameter tolerance become smaller than normal. sometime the max diameter become smaller.....


when you need mod thread gages, just send us your drawing or print or your thread data, we can delivery correct thread gages to you in 4 weeks.
