What does a no go thread gauge check?
In respect to this, how many turns can a no go thread plug gauge?
three complete turns
Subsequently, question is, what is difference between GO gauge and no go gauge? To inspect hole size of a part, the Go gage is inserted into the hole. If the gage can be entered into the hole, then the hole is considered to be above its low limit. Following that, the No Go gauge is used: if it enters the hole, than the hole is too big.
Secondly, what does a thread gauge check?
A solid thread ring gauge is used to check acceptance of a “screw” – i.e. externally threaded part. The GO and NO-GO rings are normally separate pieces. A thread ring gauge is designed to check the correctness of the thread, to include thread depth and pitch diameter (to the given pitch / TPI).
What is 6g tolerance?
The 5g indicates the tolerance class for the pitch diameter and 6g is the tolerance class for the major diameter. A fit between threaded parts is indicated by the nut thread tolerance designation followed by the bolt thread tolerance designation separated by a slash.
