Lightweight and compact, yet rugged enough for production, the Series GP Johnson Gage Internal Thread Inspection System is commonly used for applications from 1.75”-6.00” (M45 – M155). Equal and simultaneous constant force expansion from a centralized spindle allows oscillation of either Setting Master or product in any direction without altering System accuracy. Careful consideration of design ergonomics and overall gage balance reduces fatigue and eases any inspection operation. In-line indicator location allows easy indicator viewing regardless of gage position in either Bench or Portable application. The GP Series is available in either a fixed or adjustable mode while utilizing the 120 degree tri-rolls for Functional Diameter, Pitch Diameter, Minor Diameter and Major Diameter contact profiles.
