Setting Rings and Setting Master
for internal bore measurement

These sizes of setting rings are specifically used to calibrate ingages, intrimiks, holtest and other inside micrometers. The rings can be used to check and verify either the high or low range of most of these micrometers. The 1" ring, and larger, can also be used to calibrate the ID jaws of calipers.

Each ring will have the actual size stamped on it. This means that when you order a 1" ring, the item you get may be stamped 0.99998 inches. It would be very costly to manufacture rings exactly to the nominal value, and that's why you'll get something very close instead.

 

 

The B&S rings offered below come with a manufacturer's certificate of accuracy and traceability to NIST standards. You can use the rings just as they are, because the manufacturer guarantees their accuracy. However, your quality system may require certification with data. You can have this done at time of purchase or you can have it done at a nearby calibration lab.

The rings "made in India" and those made by Mitutoyo come with a manufacturer's certificate, traceable to International Standards. International Standards are accepted in place of NIST by international agreement. The certificate is dated at the time of manufacture and may be several to many months old at time of purchase. You will have to decide if this is sufficient for your purposes. Otherwise, request the NIST certificate as offered below.

Now you'll simply have to decide which flag to wave.
