Gauge, Go/No-Go, 3 1/2", Pace
Part No. 4006
Because they simulate a pipe coupling, Pace GO/NO GO Gauges are an excellent tool to use for quickly determining accuracy of groove depth. After a groove is rolled, the appropriate gauge is matched to it. If the gauge will not fit, the groove is too shallow; if the gauge slides past its No-Go marking, the groove is too deep. Made of steel and hard-chrome plated for durability, these gauges are easy to use and remain permanently accurate. GO/NO-GO 3 1/2"
