it combines a straight shank with a stub-length body for rigidity and accuracy

JBO Thread Ring Gauge (NoGo) - Metric Fine - Left Hand - 6g - M5 x 0.5 End Mill Holders reducing guesswork during assembly andIntroducing the JBO Thread Ring Gauge (NoGo) for metric fine threads. This left hand gauge is calibrated for M5 x 0. 5 external threads in 6g tolerance, helping engineers, machinists, and quality teams quickly confirm whether a parts threads conform to specification. Designed for reliable Go NoGo inspection, it makes it easy to identify non conforming components at a glance. Precise metric fine compatibility (M5 x 0. 5, left hand): Specifically
