How To Use A Pin Gauge. 2) the next larger pin does not go in the hole. Heres a quick primer on gage pins and how to use them to measure small holes. calibrate your micrometers. and use them as go/no go gages.
Plug and Pin Gages Information Engineering360 globalspec.com
The size of a hole is defined by the largest pin gage that can be fully inserted and extracted in that hole using only a light finger grip of the sides of that gage. The hole size is smaller than the pin. If you internet search go nogo gage. or similar. youll find plenty of references.

The maximum or “no go” pin should be used for the upper limit. it should not fit under slight pressure. They are used in the manner of a plug.they are generally assembled from standard parts. where the gauge portion is interchangeable with other gauge pieces (obtained from a set of pin type and a body that uses the collet principle to hold the gauges firmly.

It should be able to easily fit into the hole with no force. The general rule of thumb when using a pin gauge is as follows:
This Is Also True For Other Class Pins.
To use this style of gauge. one end is inserted into the part first. and depending. Plug or pin gauges are simple and accurate cylindrical gauges used to check if manufactured holes or thread are within limits. 2) the next larger pin does not go in the hole.
The Maximum Or “No Go” Pin Should Be Used For The Upper Limit. It Should Not Fit Under Slight Pressure.
Working devices are used for dimensional inspection and checked periodically against a master gage. The general rule of thumb when using a pin gauge is as follows: In diameter. and used to set or check micrometer or other od gages.
To Begin With. Let Me Say That A Gauge Pin Should Never Be Forced Into A Machined Hole.
Behalf of checking the diameter plug gauge also use in comparing. setting. calibrating of other gauges. Master gage blocks. master or setting discs. and setting rings are master gages used to calibrate or set working plug or pin gages. What is pin gauge the pin gauge is the pin shape according to fixed size precisely.
1) Pin Gauge Will Tell (When The Pin Goes In The Hole). That The Hole Is Larger Than The Pin.
If is also possible to use the diamond shaped gage illustrated below. As an example. deltronics class x and xx gage pins can fit within a diameter (that has form within the range) to.00002. The largest pin that can be fully inserted and extracted using only light finger grip on the sides of the gauge is what will determine the hole size.
Otherwise. Youll Be Measuring The Rifling Leade And Then The.
They are used in the manner of a plug.they are generally assembled from standard parts. where the gauge portion is interchangeable with other gauge pieces (obtained from a set of pin type and a body that uses the collet principle to hold the gauges firmly. Plug gauge is used for assessment of hole or diameter of an object. 3)you could use the average of the two pins (fit and notfit) for the hole size. but it is not accurate.
