Plug & Ring Gauges

 

Haas offers a full range of Plug & Ring Gauges made from hardened steel, rated at 58-63 HRC. Plug and ring gauges are designed for GO/NO-GO testing of threaded features on machined parts. Ring gauges are meant to check external threaded features while plug gauges are ideal for checking internal threaded features. Both gauges ensure thread quality and pitch diameter are within tolerance. Haas plug & ring gauges are manufactured to ANSI B1.2/DIN ISO 1502 standards. An inspection report is included with each set and/or individual gauge, outlining the true measured dimensions.
