JBO Thread Plug Gauge (GO) - Metric Fine - Right Hand - 6H - M58 x 4 Shrink Fit Holders straight-shank hand reamer uses HSSThe JBO Thread Plug Gauge (GO) Metric Fine is a precision Go gauge designed to verify metric fine threaded holes. Specifically configured for M58 x 4 with a 6H tolerance and right hand thread, this gauge helps inspectors and machinists confirm that a hole will accept a true fastener and meet required standards. Made from hardened steel, the gauge resists wear and maintains accurate dimensions even in busy workshops. The knurled, cylindrical body
