Accusize Industrial Tools Minus Pin Gage Sets
Accusize Minus Pin Gage Sets
- Class ZZ
- Each gage is electro-etched with its actual size.
- Tolerance for minus set tolerance: +0.0000" / -0.0002"
- All gages are 2" long, center less lapped.
- Hardness: Each Accusize pin gage is heat treated to a hardness of 60-62 Rockwell C drill rod, providing the pin gages higher durability and quality.
- Finish: each gage has a 10 micro finish or better.
- In strong case.
Briefly introducing pin gage
Pin gages, also known as plug gages, manufactured with a specific size and durable materials, are used to test hole sizes, especially small holes and to verify the diameter of holes and slots. They are used to quickly determine whether hole sizes are within certain tolerance or not. Moreover, they’re used as test bars for geometric deviation measurement.
They're commonly used in combination with go/no-go pin gage handles to produce a "Go-No Go" gage that quickly qualifies a bored hole. Pins are especially useful for gaging the straightness of a relatively deep bore. The Accusize go/no-go pin gage handles can work with our pin gage sets to produce a “Go-No Go” gage. These handles can be purchased separately.
Features:
- Each pin gage set comes with a Certification of Performance.
- Class ZZ Tolerance
Measuring Small Holes with Pin Gauges
- Calipers are unreliable for measuring small holes; therefore, we need pin gages.
- Accusize pin gages range widely from 0.011" to 1.000". You can use them to measure a huge number of small holes.
Cautions when using pin gages:
- Prepare pin gage handles (Go/No Go handles).
- Clean the measurement surface with a benzine or a dry cloth.
- Wear gloves to prevent body temperature influencing the accuracy of the measurement. The temperature difference between your hands and pin gages may lead to an expansion of the pin gage.
- Remove dust and fingerprints. Then, apply anti-rust oil to save the tool life.
- Keep the pin gages in the environment with small humidity changes and temperature variations.
Calibrate Micrometers
- Pin gages are a good deal in common as calibration for micrometers and calipers.
- For example, you can use a 0.300” pin gage to verify the micrometer shooting for 0.300”.
Go/No Go Gage Handle
- You can purchase our Go/No Go pin gage handle separately, so that you can use it with our pin gages to produce Go/No gage.
- It will be ideal to check a workpiece against its allowed tolerance via go/no-go test
- Put the pin gage inside the Go/No Go pin gage handle. If it fits the Go side, it is within tolerance of the hole. If it fits the No-Go side, it is out of tolerance of the hole.
Measuring Groove
Verify the accuracy of a groove width of a work piece after processing by sliding the pin gage through the groove
Measurement between holes
You can use pin gages to measure the distance between holes. The formula is shown in the picture.
Change of packaging
- To meet the challenges of shipping in e-commerce, we’re continuously upgrading the outer packaging of our pin gage set, which were packed in fragile plastic cases and are then redesigned.
- Accusize pin gages are now packed in strong plastic cases and some of them are in reliable and beautiful aluminum cases.
- We keep upgrading the packaging. Some of the pin gage sets come with really solid cases and packaging. In the future, we will make it stronger and stronger.

Been wanting a set of gauge pins for a while. These measure right on, are packaged nice, and you won't find a better price. I've bought quite a bit from Accusize and never been disappointed

These are a necessity to measure hole sizes accurately. Well packaged work great for reloading.

Good set but every pin is out of tolerance.The certificate says less than 0.00002 from 0.010 to 0.250.Every pin is 1/2 thou (0.00005) small.So if you are sizing for slip, glide or press fit, these do not have the precision needed even though they are sold as better than 2 ten-thousandth (200uin aka 2 tenths).

I've bought two of these - one for my work box and another for my home shop. One arrived intact, the other came with a busted handle.The case is generally junk. It opens too easily and will dump the pins out if you don't open it flat. The clasps aren't confidence inspiring.The pins are accurate as can be expected. No complaints on diameter accuracy. I wish they had better etched markings and bevels, but you get what you pay for.

They measure accurately and are decently hard so should hold up fairly well. Only minus is the ends arent ground flat so not good for measuring depths pf holes but otherwise a great value.

I like the great assortment. I always have just the right size. I use these to indicate a barrel for chambering and crowning the barrel.

My original order arrived damaged: the outer shipping box was intact, but the contents had come apart. The replacement order arrived with similar internal damage.

The finish on these are excellent. Checked the diameters and they are spot on. These will see a lot of use in my job.
