Which type of plug gauges has go and no go sizes?

Reversible wire plug gages are held in a collet-type handle that forms either a single-end or double-end Go, No Go Gauge Assembly. Reversible wire plug gages are available in a range from . 004″-1.000″, and in a tolerance range from class Z-XXX. Go and No Go Gauges are utilized for checking hole sizes.

What is the difference between go and no go gauges?

The GO is testing the maximum material condition. A NOGO cylindrical plain gauge is intended not to go into/onto the piece being tested. The NOGO is testing the minimum material condition. A Master cylindrical plain gage is intended to be used as a master for setting another tool or gauge to size.

How accurate is a go no go gauge?

The industry standard is referred to as the Ten Percent Rule. This common rule of practice requires that 10% of the product tolerance is divided between the GO and NO GO gauges. This rule results in the possibility that 10% of good product may fail inspection but that no bad product would ever pass inspection.

What is the least metal limit of GO plug gauge?

Example 2: For a shaft: Maximum Metal and Limit of shaft (high limit of shaft) = 37.98 mm “GO” gauge dimension become = 37.98mm Minimum Metal Limit of shaft (low limit of shaft) = 37.96 mm “NOT-GO” gauge dimension become = 37.96mm.

Why are go no go gauges used?

Go – No Go gauges are manual mechanical measuring tools used in production lines to guarantee the machining has taken place and it has been performed correctly. They differ from each other based on the type of surface check being performed; for example geometry and/or dimension.

Do I need a no go gauge?

A no go gauge is useful for checking if something has changed. If the firearm did not close on a no go ,and it does now, you for sure have a problem. In reality if it closes on a no go gauge some investigating needs to be done.

What does no go gauge mean?

A go/no-go gauge refers to an inspection tool used to check a workpiece against its allowed tolerances via a go/no-go test. Its name is derived from two tests: the check involves the workpiece having to pass one test (go) and fail the other (no-go).

What is thread no go Gage?

GO NO GO thread gauge is thread inspection tool for checking thread. the go end should go through the entire thread, the NO GO end should be stopped between the thread of work-pieces. If not like so, then we can judge that the thread of work-pieces are not well enough.

What is go Gage?

Definition of go gage. : a limit gage that will just go in or on the part being tested — compare no-go gage.

What are gauge pins?

Definition of gauge pin. : a pin attached to the tympan of a platen press to hold the sheet and act as a feed guide.
