Here’s a comprehensive overview of Thread Ring Gauges based on the search results,including types,specifications,and purchasing options:
1.Types of Thread Ring Gauges
Go/No-Go Gauges:Used to check thread acceptability.The"Go"end must fully thread,while the"No-Go"end must not exceed two threads when screwed by hand .
Metric vs.Imperial:Available in metric(e.g.,M16x2,M3x0.5)and imperial(e.g.,0.375-24UNC-2A)thread standards .
Adjustable vs.Fixed:Adjustable ring gauges(e.g.,Vermont Gage)allow recalibration,while fixed gauges(e.g.,Volkel)are pre-set .
2.Key Specifications
Thread Size&Pitch:Examples include M16x2(2mm pitch)1,M10x1.25 6,and M3x0.5 .
Tolerance Class:Common metric tolerances are 6g/6H;imperial uses 2A/3A or 2B/3B .
Material:Typically tool steel(hardness RC 60-62)or HSS(high-speed steel).
Calibration:Some come pre-calibrated(e.g.,Volkel with IAC thread scanners)1,while others include NIST-traceable certificates .
3.Applications
Quality Control:Ensures threaded parts meet manufacturing standards .
Industrial Use:Common in metalworking,automotive,and aerospace industries .
Compatibility:Used with thread plugs or micrometers for precise pitch diameter measurement .
