Double Sided GO/NO GO Plug Gauge

Double Sided GO/NO GO Plug Gauge is a precision plug gauge designed with both the GO and NO GO ends integrated on a single handle, allowing operators to quickly verify whether a hole diameter falls within specified tolerance limits. The GO end checks the minimum allowable dimension and should enter the hole smoothly, while the NO GO end verifies the upper tolerance limit and should not enter the hole if the part is correctly machined.
