JBO Thread Plug Gauge - Metric Fine Go/No-Go - Left Hand - 6H - M17 x 1 Face Mill Arbors - Through Coolant and achieve repeatable results inThis JBO thread plug gauge is built for checking M17 x 1 metric fine threads in a left hand configuration. It supports machinists, inspectors, and quality teams who need to confirm that internal threads meet the required 6H tolerance before parts are assembled, helping avoid fit issues in precision work. Go No Go Efficiency: The dual ended design lets you verify thread acceptance in seconds, reducing inspection time on every hole. Hardened Steel
